Multinational companies within the supply chain purchase cheap materials from around the world through ICT technology, and based on this, take an economic system based on scale. This is to establish a leading company structure that increases market share by lowering long-term average cost and securing price competitiveness by producing at a lower price. One of the key roles in this supply chain is information, and if a big data system based on this much information can be linked to import and export customs clearance, it can play a positive role. In the structure of export and import transactions and customs clearance, the cost incurred in administrative aspects is much higher than the cost of transporting and unloading cargo. As these management costs increase, the importance of the supply chain in trade is constantly being demanded, and in the process of supply chain in trade, trade-related fraud is still prevalent in exports, imports, and customs clearance. There are huge losses in import and customs procedures.

At this time, research and development have been conducted to incorporate blockchain into import and export procedures to solve the structural problem. In this regard, Korea Patent Registration No. 10-2251607 (published on May 13, 2021) and Korea Patent Publication have been conducted.

Before explaining the configuration of FIG. 2 below, a simple concept of each block chain for understanding FIG. 2 will be described first. Contents and concepts described below will not be redundantly described while describing FIG. 2 .

<Public Blockchain>

A public blockchain is a blockchain in which nodes can freely participate in the network without approval from an authoritative organization. In order for an organization to conduct business using blockchain, it must consider whether the business satisfies the seven business requirements of effectiveness, efficiency, confidentiality, integrity, availability, conformity, and reliability. However, when an organization conducts business by utilizing a public blockchain, it cannot satisfy business requirements due to the four chronic limitations of a public blockchain. The four limitations of public blockchains are as follows.

First, low transaction throughput and high latency reduce the effectiveness, efficiency and availability of the business. In Ethereum, a public blockchain, 20 transactions are processed per second, and a delay of 10 to 20 seconds occurs per transaction. Compared to 2,000 transactions per second with credit card payments, public blockchains have great limitations in conducting businesses that require rapid payments. Second, the lack of privacy and confidentiality protection reduces business confidentiality and compliance. In a public blockchain, each node stores and processes blocks containing personal identification information and organizational transaction information for block integrity and transparency. This not only violates the requirements for handling personal information specified in the Personal Information Protection Act, but also causes confidential transaction activities of organizations to be disclosed to network participants, which greatly hinders business conduct.

Third, the lack of blockchain governance reduces the effectiveness, efficiency and compliance of business. A public blockchain that is capable of hard fork and difficult to control nodes prevents organizations from conducting business with strong and consistent strategies and policies. Such an environment makes it difficult for organizations to conduct business effectively and efficiently, and also makes it difficult to satisfy the requirements of stakeholders. Fourth, business efficiency deteriorates due to inefficient energy consumption. Public blockchains consume energy such as computing power and power for proof-of-work. Considering that the Bitcoin network consumes 14.96 Twh of power and $747 million per year in proof-of-work, excessive energy consumption and unfriendly factors lead to inefficient business. Due to the limitations of these public blockchains, organizations must select a blockchain that can satisfy all business requirements to conduct business.

The greatest significance of blockchain technology is that transactions between individuals are possible without an intermediary that guarantees trust in a network environment where mutual trust is unreliable. In this environment, in order to guarantee trust that transactions between individuals are not forged or tampered with, public blockchains have critical limitations in terms of efficiency, confidentiality, and availability essential for business execution. However, the actual environment in which organizations do business and transact is not as extreme as the trustless network premised by public blockchains. This is because an organization conducts business by transacting and collaborating with entities that are generally considered trustworthy. In other words, the fundamental cause of limitations in using public blockchains for business comes from the extreme premise of trustlessness, and if the premise is converted into a trustworthy environment, existing limitations can be resolved.

<Consortium Blockchain>

The basic premise of a consortium blockchain is a trustworthy environment among network members. In a consortium blockchain, members who trust each other make decisions through consensus and cooperate to operate the network in a decentralized way. In addition, the consortium consists only of trustworthy and accountable organizations that meet the network objectives. Because it is a trusted environment composed of members with approved and clear subjects, consortium blockchains allow businesses to be conducted effectively and efficiently without being bound by the fundamental limitations inherent in public blockchains. The consortium blockchain can comply with business requirements for reliability, efficiency, availability, integrity, and confidentiality due to its trustworthy environment. Organizations can use efficient consensus algorithms to maximize transaction processing speed and conduct business that requires immediate settlement. In addition, since there is no need to use a consensus algorithm that requires excessive energy consumption, blocks can be verified efficiently while maintaining integrity. Since transaction details are disclosed only to authorized stakeholders, it can solve the problem of privacy or confidentiality being compromised.

In addition to the five business requirements described above, consortium blockchains can achieve organizational goals with effectiveness and compliance. In the consortium blockchain, members can decentralize and cooperate to carry out governance so that the organization's blockchain utilization strategy and policy are aligned with the organization's goals and value is delivered to stakeholders. Governance that directs and supervises compliance with external requirements, evaluates strategies and policies, and effectively operates the network can be most appropriate in a consortium blockchain operated through consensus and voting among members in a trustworthy environment.

IT governance refers to the leadership, organizational structure, and processes that enable IT to maintain and extend the organization's strategy and objectives as part of corporate governance carried out under the responsibility of the board and management. The international standard ISO/IEC 38500:2015 defines IT governance as an activity in which the current and future use of IT is directed and controlled by top management. Top management evaluates current and future IT use, directs through strategies and policies to ensure that IT use achieves business objectives, and monitors policy compliance and performance against strategy. Accordingly, the service according to an embodiment of the present invention, in the case of public data or data that can be shared by anyone, is distributed and stored in a public blockchain, but is stored in a light node rather than a full node so that the speed does not slow down. Data that should not be hijacked, including personal information and biometric information, is stored in the full node of the private chain, and the initial generation key generated by authentication should be kept by the user. By having the consortium blockchain, which is a trusted institution, recover and reset, each information is dualized into full node and light node, and each blockchain is also converged according to its use, but selectively used to provide fast and reliable services.

Referring to FIG. 2 , the setting unit 310 may set data input from at least one node constituting a blockchain to be distributed and stored. At least one node may include a seller terminal 400, a buyer terminal 100, a logistics company terminal 500, and the Korea Customs Service server 600. At this time, the blockchain may be a consortium blockchain. In addition, the blockchain may be a private blockchain or a structure in which the two are converged. That is, real-time data or various transaction data is recorded in the consortium blockchain, and the seller terminal 400, the buyer terminal 100, the logistics company terminal 500, and the Korea Customs Service server 600 participate as nodes in the private blockchain. can be In addition, the blockchain may be a cloud-based blockchain (Blockchain as a Service).

The upload unit 320 may receive and upload at least one product registered from the seller terminal 400 . The seller terminal 400 may register at least one type of product and receive order details. At this time, if the seller of the seller terminal 400 is a domestic person, data can be shared with the buyer of the buyer terminal 400, which is an overseas importer, through a blockchain network for real-time domestic sales details of domestic products.

The delivery unit 330 may transmit product information and payment information to the logistics company terminal 500 and the Korea Customs Service server 600 when at least one type of product is ordered from the purchaser terminal 100 . The purchaser terminal 100 may order and pay for at least one type of product. The logistics company terminal 500 may start a logistics process based on buyer information and product information input by the seller terminal 400 .

At this time, since the type, shape, volume, weight, etc. of the cargo is different, and the waiting time, loading and unloading difficulty, cargo turnover rate, and the size of the volume are different, basic data may be input from the shipper and the borrower, and the borrower and the shipper may be matched or recommended. . Of course, in the case of a shipper, the delivery of cargo of similar size, type, shape, etc. is consigned, or the borrower is also mostly small, so there is a high possibility that only one cargo vehicle exists, so the initially entered data can be used for later recommendations as default . In addition, the fundamental reason for the distortion of freight rates is the structure of the freight transportation market. Information asymmetry, which virtually monopolizes information, can be resolved.

The tracking unit 340 may transmit transport information to the seller terminal 400 and the buyer terminal 100 when transport information is uploaded from the logistics company terminal 500 . At this time, the seller of the seller terminal 400 becomes the shipper (summarizer), the logistics company of the logistics company terminal 500 becomes the borrower (loser), and a transportation contract is established according to the contract for the third party (beneficiary = buyer). . Here, in the case of matching the shipper and the borrower, the accumulated contract items are analyzed and the parties to the contract are matched based on the transaction propensity, and the results of big data, artificial intelligence, and modeling can be used. For example, by analyzing the relationship between the positive and negative ratios for each contract, the type of contract with the most positive and negative tendencies, the type of contract, and the basic data of both parties, it is possible to know which party to match in the future. . For example, Naive Bayes can be used to extract Korean words, frequencies, and statistics for determining positive and negative propensity, and a decision tree is extracted from Naive Bayes. It can be used to intuitively classify data by word, and can extract the distance between classified data groups using K-nearest neighbor, and Apriori as an association rule analysis, decision tree and Based on KNN, it is possible to analyze the relationship between key keywords.

Naive Bayes is used to classify documents and record the number of times for specific words, and is a method of selecting an item with a high probability between two classification items as part of Bayesian theorem. Bayes' rule uses p(c|x)=p(x|c)p(c)/p(x) to classify data with conditional probability. When we define x as the input data and c as the classification item for data classification, we can know p(c|x) with p(x|c) known. At this time, when Bayes rule is applied, p(ci|x,y)=p(x,y|ci)p(ci)/p(x,y), and two rules, p(c1|x ,y) and p(c2|x,y), the probability of belonging to category c1 based on the data identified as x,y can be obtained. Bayes' rule can be used to compute the unknown from known data.

A decision tree is used to classify a data set, and has a form in which a recursive classification process is repeated until the data set is classified from the first parent node. Among the methods for determining data division, a quantitative method is applied, information gain is calculated, and attributes of each node are checked to proceed with division. At this time, the formula L=log2p(xi) is used to calculate the probability that a classification item is selected. Here, p(xi) is the probability that the classification item of xi is selected, and the information measurement method for information gain is the entropy of H=-Σ(xi)log2p(xi) (i is from 0 to n) Use a calculation formula. Calculate the entropy H using the probability (xi) of the classified data item L and add them all together. Finally, by comparing changes before and after comparison, the index of the best attribute is returned, and by repeating the previous process, data can be classified for the attribute with the highest information gain (entropy).

K-Nearest Neighbor is the most well-known algorithm in the pattern recognition field. For data classification, all existing data (classified data items are required) and new data are compared, and the distance to the top k most similar data is measured. a way to classify. A method of measuring the distance may use Euclidean distance. The distance can be calculated with attribute values between two data groups. In order to obtain the distance of each attribute value, integer-type numerical values are used as attribute values, and data can be normalized for this purpose. Normalization is user-definable, such as 0 to 1 or 1 to 1. Normalization is performed using the smallest and largest values in the set, and the maximum and minimum values used in the normalization process can be used to predict distances for unclassified types by determining close distances.

Apriori is an algorithm that finds rules that can most appropriately explain the major relationships observed in data variables such as association rules, preferences, and information filtering. It can be used to find important relationships between data with high multidimensional or complex relationships. In the Apriori algorithm, relationships are expressed in two forms: frequent item sets or association rules. The frequent item set is a collection of items that occur frequently together, and the association rule suggests that there is strength in the relationship between items. In a specific data set, the relationship to the item set can be determined using the above two methods. Support is a type of clustering in which the ratio and reliability of a data set that includes specific data in a data group are defined by an association rule to group highly correlated data, and can be used to find data that is highly likely to satisfy the purpose simultaneously. Of course, it will be obvious that in addition to the above-described method, it is also possible to derive propensity from each contractual relationship with various algorithms and model big data based on cases.

The monitoring unit 350 may transmit the export/import status and customs clearance status to the seller terminal 400 and the buyer terminal 100 when the customs service server 600 shares the status. The Korea Customs Service server 600 may receive payment information of the purchaser terminal 100 and share the import/export status and customs clearance status.

The automation unit 360 uses smart contracts to perform transaction processes including order, payment, settlement, delivery processing, import and export declaration and customs clearance procedures for assets contained in the blockchain according to the achievement of predetermined conditions. Contracts can be automatically executed. A smart contract is a software code implemented on a blockchain platform that guarantees that contracts are automatically executed for assets contained in the blockchain according to the fulfillment of pre-determined conditions. In other words, smart contracts are automated self-enforced agreements, which combine the two processes of contract establishment and execution into one through blockchain technology. The technical concept of a smart contract is a kind of program that automatically executes according to an event instructing the transfer of assets to the ledger while the transaction records are distributed and stored, distributed and shared, and the replicated ledger is operated and stored. -driven program).

On the other hand, smart contracts are legally required to ① have two or more parties, ② relate to the transfer of assets from one party to the other, ③ the implementation is automatic, and once the contract is initiated, is a contractual concept that does not require human intervention. In this respect, a smart contract as a contract law element is a kind of algorithmic contract.

However, smart contracts are distinguished from algorithmic contracts in that they can form a decentralized autonomous organization (DAO). Smart contracts are executed automatically without human intervention, so they do not value the trust of the parties. Therefore, it is a kind of so-called conditional nature in which the problem of non-fulfillment of the contract, which is the biggest weakness of the contract, is not dependent on the credit of the other party but is determined by the fulfillment of programmed conditions. Therefore, in smart contracts, interpreting, judging, and evaluating the fulfillment of conditions becomes a legally important issue, and the setting of conditions does not exclude that each party sets them or sets them by agreement as described above.

Transactions in smart contracts are made in the order of ① programming code writing, ② code signing, ③ blockchain storage, and ④ transaction execution. The program code and the result executed here are included in the transaction and stored in the form of a database in a block connected by a chain, so that all participants share the transaction information, and the transaction details and contract details are distributed on the Distributed Ledger without addition or change. ) are stored independently of each other. Here, participants sign contracts and sign electronic signatures by linking the wallet address created by the public key encryption method with the blockchain. A smart contract transaction is a computer protocol designed to make it easy and convenient to execute or prove the execution of a contract on a network. Although these transactions can be traced, they have irreversibility that cannot be reversed or changed. At this time, functions including Turing-Completeness, Value-Awareness, Blockchain-Awareness, and the concept of State may be provided.

When an event is generated in the seller terminal 400, the buyer terminal 100, the logistics company terminal 500, and the Korea Customs Service server 600, the transaction management unit 370 generates a transaction unique ID (TX HASH) for each subject. , record the sender and receiver of the transaction, and classify the transaction by type into a preset classifier (TX TYPE) and store it for viewing. At this time, the transaction management unit 370 may prevent illegal transactions by detecting double-spending. At this time, double payment means making two or more transactions with one electronic money, and corresponds to an illegal transaction. Currently, blockchain adopts a method of recognizing a chain with more blocks connected as a valid transaction when a branch occurs in a chain in which blocks are connected. Since the possibility exists, illegal transactions cannot be completely prevented by the length of the chain alone.

Therefore, in one embodiment of the present invention, a method of detecting double spending and a method of notifying other nodes after detection may be further used. To this end, the automation service providing server 300 performs transaction backtracking. The transaction has a unique TXID, and the transaction is connected to the double payment detection algorithm input and output of the blockchain, so it can be referenced using the TXID. . All transactions can be found in blocks because the connection from IN to OUT can be continuously followed using the TXID of the transaction. At this time, if an attack is attempted to include the double-spending transaction in the blockchain, a random node will have the existing blockchain and the branched blockchain created by the attacker. At the point of divergence, it is usually not immediately obvious which one is normal.

When the blockchain that the node has first is called Active and the branched blockchain is called Forked, there is a possibility of double-spending only when multiple forks occur in the blockchain. run the algorithm To determine whether there is a double spend, the first step is to check whether the blockchain forks. This is because for double spending to occur, there must be a fork. When two transactions being compared have the same OUT TXID of the previous transaction and different IN TXIDs of the current transaction, this corresponds to a double spend. Since one output was referenced as two inputs, more than one transaction was performed with one cryptocurrency. In this case, a warning message can be propagated to notify other nodes of the occurrence of double payment.

When the data management unit 380 stores data transmission and reception between the seller terminal 400, the buyer terminal 100, the logistics company terminal 500, and the Korea Customs Service server 600 in the blockchain, the data for which the preset speed must be guaranteed is In the Light Node, data that needs to be kept confidential can be set to be stored in the Full Blockchain Node. That is, the data management unit 380 stores data that requires a short access time or speed in the light node, and data that needs to be kept confidential even if the speed is slow, such as other personal information or authentication information, is stored in the full node (Full Blockchain Node ) is stored in

At this time, the light node is a node that participates in the blockchain and performs transactions, and performs a function of verifying individual transactions by requesting transaction data from the full node. It does not have the original source of all block information like a full node, but only a kind of summary, that is, the important data in the block header. For smartphones, Android mobile Bitcoin wallets are used as light nodes, as not many phones have 100GB storage space yet. For reference, the Bitcoin wallet on the desktop computer is used as a full node. Since the light node does not have all block information, it cannot verify whether the transaction is normal when it receives any new transaction information. Conversely, in the case of a full node, since it has all the data, it can be verified by querying local block information. Therefore, light nodes use Simple Payment Verify (SPV) to verify transactions for individual transactions. SPV is a method of requesting block information from a full node to verify a transaction in a light node and confirming whether the transaction is a verified transaction through the Merkle Tree.

Blockchain does not store and manage transaction records in a centralized server, but individual servers participating in transactions gather to maintain and manage the network. These individual servers, that is, participants, are called nodes. Since there is no central manager, the role of the node distributing the block is important, and a new block is created only when there is an agreement of more than half of the participating nodes. The nodes store the blockchain in their computers, and even if some nodes are hacked and the existing contents are distorted, the data remains in the majority of nodes, so the data can be continuously preserved. If it has all the transaction information of the blockchain network, it is called a Full Blockchain Node, and if it has only the Merkle Tree, it is called a Light Node.

Therefore, all nodes in the blockchain are divided into full nodes and light nodes. A full node stores all transaction information on the network and manages users' wallets. Light nodes store user wallets but rely on full nodes for network access. A node is a component of a network, and it can be understood that a full node maintains the blockchain, and a light node grants access for participants. Taking the analogy of a vault and a watchman as an example, a full node is a military-level reinforced watchman, and a light node can be seen as a channel for depositing and withdrawing money using a vault. Among full nodes and light nodes, it is the full node that contributes the most to the blockchain network. Ultimately, this is because light nodes and individual nodes participate in the network by reading the blockchain stored in the node.

The advantage of a full node is that, for example, complete security of Bitcoin transmissions is possible. Since the transmission data is sent from its own node, no one knows where the transmission originated. Light nodes are not completely secure because the transmission data goes through the central server. However, not being completely secure does not mean that the risk of Bitcoin hacking increases. Information that can be exposed means that information about which address was sent from which IP can be left on the server. In contrast, full nodes do not know which address is sent from which IP. This is because when a random node forwards a coin transfer to another PC, the PC that receives the random broadcast does not know whether the transfer was sent by me or something else. In addition, full nodes allow easy input and output of private keys. This is a method that can be easily used in full node Bitcoin Core. When creating a paper wallet, you need to extract a private key, but extracting and entering the private key is simpler than other light node wallets.

Conversely, the advantage of a light node is that it is easy to use. Instead of using its own block, the central server checks how much my balance is. Therefore, it takes very little time from installation to use and is easy to use. In the case of a full node, block data reaches 140GB, so it may take 2 to 7 days to receive all of these blocks. Also, light nodes are easy to recover. Since the address is managed using the seed method, wallet recovery is easy. If you write down 12/18/24 English words well, even if your wallet is lost, you can use these words to recover your wallet. Conversely, full nodes must be somewhat proficient in using PC commands to be able to use them stably without losing their wallets.

It can be stored in at least one Full Blockchain Node constituting the blockchain, and the initial creation key can be transmitted to each individual entity constituting the system. At this time, the personal authentication data and personal information data are stored in a personal electronic wallet format and can be viewed with an initial generated key value. Here, cryptocurrency electronic wallets can be divided into hot wallets and cold wallets. A hot wallet is a cryptocurrency electronic wallet that is always connected to the network and is always online. The cold wallet is connected to the network only when the cryptocurrency wallet is used and normally exists offline. It refers to a cryptocurrency hardware wallet that enhances security by preventing network hacking by storing cryptocurrency offline. Hot wallets can be accessed with a smartphone app or PC, and cold wallets are offline, not connected to the Internet, such as hardware such as USB or paper printed with private keys. Cold wallets are safe, but they are burdensome to store and carry. . To use cold wallet more safely, you should follow the following principles. It includes principles such as generating a private key in a secure offline environment, creating a backup of the private key and storing the backup key in another location, and encrypting the wallet to prevent theft of actual cryptocurrency when the hardware wallet is stolen.

At this time, in order to manage the software key (initially generated key), multi-factor authentication, that is, a method of using a private key and additional authentication technology, should be considered, and multi-signature, that is, n A method of protecting network users with a structure in which authentication is possible only when there are m (m<=n) signatures among the private keys may be used. At this time, the initially generated key may perform multi-factor authentication, and this method may be a hint described later. At this time, in order to collect personal information, the data management unit 380 may collect and store information that only the individual can identify without indicating the individual, such as a photo, in the light node. In this case, you can use a bot. Here, the bot may be a web macro bot, but is not limited thereto. A macro program is software that automatically programs and handles simple/repetitive tasks. Simple tasks using a computer are performed automatically and repeatedly by inputting tasks such as keyboard and mouse input values and input sequences, which are normally performed manually, in advance. is used to increase the efficiency of Automating simple/repetitive tasks using macro programs is necessary for efficient business processing, and macro programs can be configured in such a way as to automate permitted commands.

Meanwhile, the electronic wallet format can support ERC (Ethereum Requests for Comment)-20 Token. ERC is a standard protocol for tokens issued on the Ethereum blockchain network. Within the Ethereum network, various DApps (Decentralized Applications) exist, and each of these DApps issues different Ethereum-based tokens. ERC is like a technical standard that developers agreed to abide by while developing DApp tokens. It is a kind of guideline that must be followed when issuing tokens. The advantage of ERC-20 is that it can include Ethereum's Smart Contract. By adding specific contract conditions to token transactions, it is possible to utilize a more stable and versatile blockchain. This electronic wallet may include a keystore that stores a private key that serves to open the wallet.

The data management unit 380 may store and share the initially generated key in at least one full node constituting a consortium blockchain. At this time, the consortium blockchain subject evaluates proposals and plans for blockchain management activities through PDCA (Plan, Do, Check, ACT) performed by managers to meet the requirements of external stakeholders, directs strategies and policies, and , and monitor performance and conformance. In other words, if consortium blockchain management is a manager's activity for planning, executing, reviewing, and improving blockchain utilization, consortium blockchain governance establishes strategies and policies for blockchain utilization to suggest the direction the consortium should go. is to do In addition, it is to evaluate and monitor the performance of blockchain management, and to build trust in the consortium's use of blockchain through communication and assurance with external stakeholders.

A consortium blockchain is operated by two entities: the Governor and the Members. The governor is an entity that makes key decisions through decentralized governance of the consortium blockchain, and performs six functions of consortium blockchain governance. Members perform seven functions: development, operation, security, protection of personally identifiable information and confidentiality, node management, ledger management and transaction management of the blockchain system as the actual operation and management body of the consortium blockchain. In addition, members cooperate to operate the consortium through consensus and report to the governor the suitability of proposals and plans for blockchain utilization and performance. Accordingly, the governor directs strategies and policies to members and controls the consortium's use of the blockchain. Each member owns a private key (initially generated key) and a public key, and through the corresponding keys, is identified as an operator of the blockchain network and has the right to create and verify blocks. General users who are not subjects of the consortium blockchain cannot directly transmit transactions to the network, but can conduct business or use services through the service system of members.

When a general user sends a transaction to a service system of a specific member, the service system uses the member's private key to transmit the transaction to the consortium network. In this way, general users cannot act directly as subjects of the consortium blockchain, but they can transact and conduct business through members. The consortium block chain according to an embodiment of the present invention is a block chain managed by military or public institutions, and is defined as a block chain that manages to store and restore personal information and authentication information of each individual. Table 1 below shows the relationships, roles, and responsibilities among consortium blockchain governance entities.

The data management unit 380 may perform recovery or reset of the initial creation key using personal authentication data in the consortium block chain when each subject in the system loses the initial creation key. In this case, the personal authentication data may include biometric data including any one or a combination of at least one of iris, face, fingerprint, vein, and voice. Also, the initial generation key may be a hash value based on a hash function, and since the public key-private key structure and hash function are the same as those in known technology, they will not be described in detail. It can be based on a hash value, but it can also use a pseudorandom number generator. An ideal random number required in information security is an unpredictable, independent, and non-reproducing number, such as a number obtained by tossing a coin. Since cryptographic algorithms or protocols of cryptosystems are designed after assuming that random numbers are ideal random numbers, it is essential to use a random number generator capable of generating safe random numbers. Random number generators include a Pseudo Random Number Generator (PRNG, Deterministic Random Bit Generator; DRBG) that generates random numbers from an initial seed value through a deterministic algorithm, and a random number that is difficult to predict from physical phenomena. It is classified as a True Random Number Generator (TRNG).

Since the output random number of the PRNG is determined by the seed, which is the input, it is common to use the output random number of the TRNG as the seed. On the other hand, in the TRNG, a digitization process is performed to convert noise sources, which are analog data, into digital data to use as an input, and a random number is output after selectively performing a post-processing process to reduce the bias of the digitized data. Since the output of an ideal random number depends on the unpredictability of a noise source, which is an input of a random number generator, it is important to identify the characteristics of a noise source used as an entropy source. Therefore, safety analysis of the post-processing process to reduce the bias of the noise source of physical characteristics must be considered in order to output an ideal random number.

At this time, the quantum random number generator of the quantum random number algorithm is a TRNG that generates random numbers using the unpredictability of quantum information. This guarantees unpredictability, unbiasedness, and irrelevance between numbers, and unlike a PRNG, a seed value cannot be tracked with an encryption pattern. At this time, the quantum random number generator is a method of generating a random number by measuring the polarization of the photon, the path of the photon, the arrival time of the photon, and the shot noise in a vacuum state. , and assigns 0 or 1 according to the location of the observed measuring device. In the case of a quantum random number generator that measures the arrival time of photons, the observation period is divided into several sections, and a bit obtained by logarithmizing the ratio of the period to the section is generated for each observation. Since the shot noise in the vacuum state is an arbitrary state having a Gaussian distribution, a random number may be generated using this interval.

In addition, ARIA, AES block ciphers, and Whirlpool hash functions may be used. At this time, ARIA (Academy, Research Institute, Agency) is a symmetric key block cipher that encrypts/decrypts 128-bit plaintext/ciphertext to create 128-bit ciphertext/decrypted text. Three key lengths of 128/192/256 bits are supported, and 12/14/16 round conversions are performed according to the key length. Round transformation consists of operations of round key addition, substitution layer, and diffusion layer. Different permutation layers are used for the conversion function of odd and even rounds, and the diffusion layer is replaced by round key addition in the conversion function of the final round. Since ARIA has an ISPN (Involution Substitution-Permutation Network) structure, the encryption and decryption processes are the same, and only the round key is different. The key scheduler consists of a key initialization process and a round key generation process. In the key initialization process, four 128-bit initialization key values are generated from the master key using the three-round Feistel structure, and these initialization key values are used in the round key generation process. Depending on the key length, round conversion is performed 12/14/16 times and key addition is performed twice in the final round, so a total of 13/15/17 round keys are generated.

AES (Advanced Encryption Standard) algorithm is a symmetric key block cipher that encrypts/decrypts 128-bit plaintext/ciphertext to create 128-bit ciphertext/decryption text. Three key lengths of 28/192/256 bits are supported, and 10/12/14 round conversions are performed according to the key length. The encryption round conversion consists of SubByte, ShiftRow, MixColumn, and AddRoundKey operations after initial round key addition (AddRoundKey), and MixColumn operation is omitted in the last round. For decryption, InvSubByte, InvShiftRow, and InvMixColumn, which are inverse transformations of functions used for encryption, are used.

Whirlpool is a lightweight hash function adopted in the ISO/IEC 10118-3 standard, and converts a message of arbitrary length into a 512-bit message digest. A block cipher with a non-Feistel SPN structure similar to AES is used as a compression function, and message padding pre-processing is required to make the input message an odd multiple of 256 bits. The round conversion consisting of SubBytes, ShiftColumn, MixRows, and KeyAdd operations is repeated 9 times after the initial key addition, and the final round conversion consists of SubBytes, ShiftColumn, and KeyAdd operations. The round conversion result value of each data block, the input data of the block, and the encryption key of the previous block are XORed and used as the encryption key of the next data block. This operation is repeated for all data blocks to generate a message digest. can Of course, it will be apparent that various methods other than the above-described encryption method are available.

This can be based on the block chain platform of port integration by improving the efficiency of ports in terms of import and export by containers, and in the case of the Korea Customs Service, in the information system related to customs clearance, it has a sharing system with shopping malls, including express delivery companies, and provides immediate Systematization can prevent false declarations and import declaration systems, and when blockchain is introduced, customs clearance with such speed is possible. Based on this, the Korea Customs Service can pursue innovation in personal customs clearance services.
