Description

[0002] Double-secured block-chain certification system and its method [

The present invention relates to a dual security block chain electronic transaction authentication system and a method thereof, and more particularly, it is possible to deal with only a smart node through which a client key is activated, and the generated block is verified double through a megabyte To a double security block chain electronic transaction authentication system capable of improving the security and improving the unreasonableness concentrated only on a specific node, and a method thereof.

Since the development of bit coin, an application based on the first block chain in 2009, the block chain has been applied to various fields such as cloud storage service, block-chain computing service as well as electronic money system such as bit coin.

Bitcoin is electronic money that is issued, stored, and distributed on a distributed network rather than a centralized organization such as the government or bank. Bitcoin has been issued for the first time in 2009 and maintains the value of money without centralized institutions until now, and it is rapidly increasing in terms of number of users and transaction size.

The background behind this bitcoin's monetary value is the block chain technology. Block chaining is a technology that maintains security and integrity in a decentralized network environment without a centralized server. Based on these strengths, it became possible to share various computing data, and it began to apply to other systems besides electronic money.

For example, in a cloud storage system using a block chain, a storage provider issues its own coin to use disk space of another computer and maintain reliability through partition verification.

As another example, Etherium is a platform that can register and execute applications that perform smart contracts for electronic money. Bitcoin simply provides electronic money transfer, while Etherium provides contractual transaction functionality.

However, the block chain has an inefficient operating structure that is wasting computing resources. Specifically, in the case of bit coin, it takes the maximum time to verify the integrity of the transaction transaction, and each participating node must store a book of about 150GByte capacity. Also, to approve a transaction, all Full Nodes must validate the transaction through the books and approve the transaction based on the verification result.

That is, all the nodes participating in the block chain must independently store the same books and perform all verification operations by the same consensus algorithm. For these reasons, the block chain is less resource efficient in terms of the overall network.

As mentioned, block chains are the core technology used for decentralized money management in bit coin. The block chain maintains the integrity of transactions by making it impossible for any user to forge or forge data in a way that distributes the books on a block chain network without a central management authority.

In order to maintain the integrity of a block chain, all participating nodes participating in the block chain network store transaction records (books) and inspect newly created transaction transactions through the stored records.

For example, when a participant node manipulates a transaction to perform a double payment, the pre-payment request is acknowledged and the post-payment request is not adopted because it is different from the book held by each of the other nodes individually. And only one payment is recognized. However, if the double payment is to be carried out in different areas at the same time, it is impossible to distinguish between the pre-payment request and the post-payment request due to the characteristic of generating a block for each node, so that two payment requests are included in different blocks Lt; / RTI > At this time, it seems like normal progress, but after a while, it is broadcast on the block-chain network, and two different blocks are encountered. Each node receives a block included in the block chain with the highest block height One block is left unrecognized on the block chain network. In this way, double payment is verified. As noted above, the approval of the transaction is denied by submitting a consensus on the request for post-settlement of double-payment requests with time differences. Therefore, data manipulation does not occur unless more than 51% of all nodes agree to be false.

However, block chaining is very inefficient in terms of computing resources usage. As mentioned earlier, all nodes participating in a block-chain network perform the same verification to verify a transaction.

This problem can be especially noticeable in the case of the ether, which must perform complex algorithms for transaction verification. For example, when performing a loan contract on an Ethernet network, a verification algorithm should be performed to verify and approve the contractor's transaction history and credit status. In this case, the conventional block chain aggregation method that performs the verification algorithm at all nodes is very inefficient and needs to be improved.

Specifically, in the case of the proof of work (POW), problems are likely to occur because there are many parts closely related to the hash such as distribution of coins and block generation. That is, if an individual or organization / organization connected to the system has more than 51% of the total hash power, it can attack with malicious intent. That is, when a coin employing a proof of work forms an initial block chain, the number of participating nodes and the risk of being attacked when the total hash power is low are increased. Also, if the total hash rate drops below a certain level as the minors move the hash power elsewhere due to the change in compensation per block and the price drop, the risk of being attacked increases.

When the first hash rate is low, a special mining machine equipped with an ASIC (on-demand semiconductor) is introduced in the CPU or GPU mining, and the hash power distributed to a large number of minors is gradually concentrated in a small number of organizations. It is against the original intent of decentralization.

In addition, the mining end time must maintain the hash power even at the time of mining so that the coin transmission and the security problem can be solved. Therefore, there is a problem that the transaction fee should be set higher.

Likewise, in the case of POS (Proof of Stake), since it is a method of receiving compensation corresponding to the share (coin) held, the more the stake, the more compensation will be received and the welfare of the rich can be deepened.

In addition, DPOS (Delegated Proof of Stake) has attempted to reduce the block generation time by improving the existing equity proofing method, but there are many parts that need to be verified in the security element, so it is difficult to use it realistically .

In the case of the combined model (POW and POS), it means a complex method of mining a certain amount of work proof method, then converting it into equity method, and allocating coins according to the amount of stock, but it has both disadvantages of both methods .

In the case of the Proof of Interest (POI), the compensation varies depending on the number of opponents and the number of trading partners, which are proportional to the amount of coin holdings. And the compensation is changed according to the coin. Compared to the existing system, the system has paid a great deal of attention to the compensation system. However, it is likely that compensation items are concentrated on the system contribution, which is favorable for maintaining the system but may induce loyalty competition. This method is not practically efficient, Do not.

Therefore, there is a need for a new consensus algorithm that can enhance security and improve the irrationality concentrated on specific users, efficiently utilize resources, and save time and money.

Korean Patent Laid-Open Publication No. 10-2018-0014534 (Title: Block Chain-based Transaction Verification System and Method, Published on: 2018.02.09)

Hereinafter, preferred embodiments of the present invention in which the above-mentioned problems to be solved can be specifically realized will be described with reference to the accompanying drawings. In describing the embodiments, the same names and the same symbols are used for the same configurations, and additional description thereof will be omitted in the following.

First, the concept of each component will be described as follows.

Proof of Key (POK) is a kind of consensus algorithm. A standard that can be a Smart Node which will be described later, which participates in forming a block chain (authentication and verification), is a qualification to a client that has activated a network while holding a key. It is a new way of giving. By focusing on complementing the shortcomings of the Proof of Concept (POW) and POS (Positive Proof) method, it is possible to eliminate unnecessary investment and unnecessary energy wasted by the proof of work method, Improved irrationality has been developed with emphasis on enhancing security while ensuring fair rewards for participants.

The client key is installed in a portable memory device (for example, USB 3.0 ROM Drive Type (Speed up to 150 MB / s)) and is connected to the super node in the ROM of the portable memory device, (Copy Prevention Algorithm using nonces counter (CPA)), which is a copy prevention algorithm using an algorithm and a nonce counter, which are required to participate in an agreement in generation.

The client key is given a hash value obtained by encrypting unique information corresponding to the individual code in the manufacturing step, and the value is inserted into the chip in the manufacturing process of the specially designed chip. The chip is designed so that it can not be re-input after manufacturing.

When the client first activates the client key by connecting to the network, Platform Management of the R2X Platform installed in the client key is activated. In the client key, the unique hash value is sent to the platform management, We will wait for the procedure to become a node.

The platform management sends a unique hash value received from the client key to each of the super nodes to be described later and requires a verification and authentication procedure.

Each super node receives a hash value unique to the client key received from the platform management and a unique hash value input from when the ALU X platform was created through a block chain Digest Transmission Protocol (BDTP) Confirm the correspondence with the unique hash value stored in the block (Megablock). If they match, they will go through the process of negotiating with the super nodes that have the megablock, and when the approval is over 80%, the client key can act as a smart node.

At this time, among the super nodes located in the vicinity of the client key, smart nodes are arranged as super nodes. This arrangement has the effect of speeding up the overall processing while keeping some of the supernodes from becoming large and balancing.

If the client disconnects the client key to the network and becomes inactive and then reactivates, the previous procedure will be retried. This method is a criterion for checking the degree of activation maintenance in the network for the next node compensation.

If a hacker simply attempts to infiltrate a smart node, it will not be possible because there is no client key.

As the smart node has been secured from the entitlement stage, it is possible to prevent the intrusion of hackers.

When the client holds the client key and is authenticated, the client key can become a smart node in the network activated state.

At the time of the transaction order including the desired option at the transaction request by the client using the smart wallet described later, the smart node goes through the verification step and enters the approved operation mode appropriate for the option before the approval operation is started. Here, the option is performed by separating the transaction request options such as the delay approval (the approval is delayed for the time set by the user and the approval is approved) and the reservation approval (the approval is made when the user sets the time).

The role of the smart node is determined as needed among the Mining Node / API Node / Seed Node / Database Index Node / Storage Node.

The smart node can establish P2P (PEER TO PEER) type storage contracts. These contracts are distributed and stored in a super node (full node) and the validity of the contract is maintained through periodic verification.

A super node is a full node and has a full block chain (a whole block from a first block (Genesisblock) to a last block (latest block)), and a block chain digest transmission protocol (BDTP), and is connected to a number of smart nodes. It is also connected to a Smart Wallet via a Smart Contract Virtual Machine (SCVM).

The super node coordinates the block chain and the megablock and maintains stable state in response to the external and external variables. It is a structure that is organically connected with the smart node and can not participate in authentication and verification between the smart nodes. For authentication and verification, all the smart nodes connected to each super node participate. For agreements derived more than 51% of the total super nodes, the entire super nodes are created and added to the block chain.

Block Chain Digest Transmission Protocol (BDTP) is a protocol that enables conversion of block chains generated by agreement between super nodes into mega blocks. It has a variable-type Digest function and is connected to the supernode

A device with a block chain digest transfer protocol has been developed to eliminate the existing serial processing structure in the connection structure with the super node and the megablock and to provide a multi data bus logic capable of dramatically increasing the processing speed in accordance with the addition of a thread (MDL, Multi-Databus Logic) technology. This structure provides a basis for reducing the burden of dual security and blocks while preventing additional processing from interfering with the overall system flow.

A Quest Gate is a gateway that connects a super node and a mega block, and is a component belonging to the block chain digest transmission protocol. Block chain digest transmission protocol.

The megablocks are generated by the block chain digest transport protocol (BDTP). Blocks that store modified information values for each block are converted by the block chain digest transmission protocol and have a specific role assigned by the super node. When a second verification is required for security reasons, the block-chain-digest-transmission-protocol uses the code of the corresponding code requiring verification on the megablock and the block-chain. Block, to perform correspondence check, etc., and sends the result to the super node. If the verification fails according to the result value, the super node discards the mega block of the corresponding super node, and the corresponding super node copies the completed mega block by the other super nodes. In order to defend a mega-block from malicious access, it is possible to construct a mega-block through the block-chain digest transmission protocol after deriving an agreement of super nodes involved in the mega-block.

The Smart Wallet includes a client identification service (RNS, R2X Name Service) function to provide a new and convenient environment for the client, so that it can be used easily by the client. Smart Wallet allows you to easily access and understand transaction details and balances, and you can trade options the way you want by choosing options when you request a transaction. In addition, the ability to interact with other smart wallets (wallets) owned by the client allows users to view all their assets at a glance without having to check each smart wallet.

Smart Wallet with this function basically works in conjunction with Smart Contract System through Smart Contract Virtual Machine.

- Supplementing the transaction procedure

This feature is not an option as a basic feature, but it adds functionality to the Wallet interactions with the functionality that many of the Wallet users have been waiting for. For the transaction request, there is an additional procedure for completing the transaction on Wallet and deciding whether to accept, reject or return the token.

(Select Button has Accept and Decline)

- Safety transaction function (escrow payment method)

It is a transaction protection function, which is a convenient and safe transaction method for transactions such as purchase of goods. Specifically, when a third party escrow service provider intervenes in the transaction between the wallets, and the buyer (or the transaction requester) determines whether to register the delivery information by clicking the button in the wallet, When the escrow service provider that has transmitted the contents to the service provider and clicks the approve service icon of the escrow service in the wallet to complete the transaction, the smart contract virtual machine is displayed in the wallet of the buyer and the seller and the escrow service provider The three requested information (buyer, seller, escrow service provider, third party transaction) is sent to the supernode, and the transaction is completed through verification and agreement. Finally, the supernode adds the block to the block chain.

Negative Confirm (Negative Confirm), which is used to protect the seller when the buyer who receives the goods does not decide whether to register the delivery information due to other reasons, And so on) and customized services that support various transaction types are possible.

- Deferred trading function

It is a function that allows the client to hold a transaction for a specified amount of time and proceed with the transaction. This option includes detailed functions such as specifying one or batching all transactions. This delayed trading option is a very useful option because it allows a certain amount of time to be spent even if an unwanted transaction request occurs due to a client error or hacking.

- Reservation transaction function

When a client makes a reservation for a transaction request reservation, it is a function to advance the transaction.

The client identification name service has the same function as the DNS (Domain Name Service) that enables the IP address to be represented in number format from the Internet in the Internet environment. It is designed to make it easy to access each smart wallet in the smart wallet. It is designed to give quick and easy access to individual transactions or other transactions by giving each smart wallet an identifier of a certain rule.

Hereinafter, preferred embodiments will be described with reference to the drawings.

1 to 5, a super node is connected to one or more smart nodes. When the smart node is activated as described above, the activated smart nodes are connected to the super node and authentication and verification operations for various transactions are performed.

A super node can be a node that has a program that can be managed like an administrator server, and such a super node has a full block chain. Such a full block chain is formed as a new full block chain by adding a new block chain by a consensus of the super nodes at a predetermined time, and each new superblock chain is held by each of the super nodes again.

As described above, the smart node is connected to the client platform management, in which the portable memory device on which the client key is mounted, sends a unique hash value assigned at the time the client key is manufactured after the client key is recognized to the super node, Is compared with a unique hash value stored in the megabyte at the time of client key creation to determine whether or not they match. This procedure ensures that all supernodes connected to the megablock participate in the consensus process and, if more than 80% agree, In other words, to activate the new smart node, it is necessary to agree on the super nodes, and the consensus is to compare the unique hash values stored in the megablock, so that it is not a method of finding out the result by substituting a large number of values, It can go fast. In addition, an agreement of more than 80% should be compared with a unique hash value in the megablock for the authentication of the new smart node. Since the super node having one mega block by the hierarchical structure may be small, Level.

In this way, the client node can authenticate and activate the smart node. After deriving the sum of smart nodes connected to the super node at various time intervals of various transaction activities, the super node generates the first block.

This primary block is connected to the full-block chain of the super node to form a new full-block chain. This new full-block chain is authenticated and verified by agreement between super nodes. In one embodiment, the agreement between the super nodes can be made at 51% or more.

The thus formed full block chain is converted into a code of a smaller size by the block chain digest transmission protocol. That is, it is converted into a specific code through a digest function, and the specific codes thus converted form a megablock. The megablock is likewise associated with the super nodes and authenticated and verified by agreement of the super nodes. In the formation of a mega block, each mega block is given a specific role, for example, a specific coin, a specific transaction, or certain content (eg, certificates, insurance content, bank balance, The development data of the company, etc.). Depending on the specific role, a stack layer is defined and stored in the megablock.

The megablock can also be formed as a megablock chain like other block chains. If necessary, a new mega block is added by the consensus of the super nodes connected to the corresponding mega block to form a mega block chain.

The validity of the full block chain can be verified by agreement between the super nodes holding each full block chain. If the secondary security is required, the validity of the full block chain can be further verified through the megablock associated with each super node have. In other words, in the case of important data, it can be further verified by a megablock outside the full block chain.

In the case of the primary block generated by the agreement of the smart node, the size of the primary block can be changed according to the amount of transactions. That is, if the size of the primary block is to be increased due to a large volume of transactions, the size of the block may be adjusted according to the size of the primary block. In the case of the size of the block, the size of the primary block may not be increased infinitely.

On the other hand, a portable memory device containing a client key may include a hardware wallet (a ruler) capable of storing a smart wallet, which allows transactions between clients and is given a client identification name, You can find it quickly.

Referring to FIG. 6, a double security block chain electronic transaction authentication method will be described. In the client key creation step, a unique hash value stored in a megabyte is given. As described above, unique information corresponding to each client code is received. This unique hash value is generated by the platform management and stored at the time of generation of the megablock of each super node.

In the client key recognition step, the hash value inherent in the client key stored in the portable memory device is recognized by the super node through the platform management, and is sent to the super node by the AltoX platform management program described above .

In the client key verification step, as described above, the unique hash value stored in the megablock and the unique hash value sent to the platform management from the client key are compared with the values sent from the platform management to the super node, % Or more.

In the smart node activation step, when the client key is verified, the smart node is activated on the network so that the smart node can act as a smart node.

The activated smart node can perform various transaction activities, participate in the first block generation step, derive more than 51% consensus through authentication and verification, and the super node generates a new first block.

In the full block chain formation step, the sum of the smart nodes is derived, and the first block generated by the super node is added to form a new full block chain by the consensus of the super nodes.

In the megablock formation step, the previously formed full block chain is converted into a megablock to be assigned a specific role by converting it by a block chain digest transmission protocol.

Hereinafter, the Smart Wallet function, the smart block, the mega block chain formation step, and the full block chain verification step are the same as those described above, and thus will not be described.

Such double security block chain electronic transaction authentication system and method have the following functions and advantages.

The super node, smart node, block chain digest transmission protocol, and megablock have a structure in which they interact with each other and are decentralized, so that the system can be infinitely expanded. For example, it is possible to construct several mega blocks according to the agreement of super nodes if necessary. These megablocks can be assigned respective roles and functions, and megablocks can be formed separately according to roles and functions. In other words, various types of transactions can be divided and stored by type, but security can be maintained.

By using smart blocks, the volume of future transactions will increase in large quantities, which can eliminate the controversy arising from the block size expansion problem. Of course, the unconditional increase in size is not good, it is good to accept large transactions, but it can get heavy. That is, the size can be expanded or reduced according to the transaction amount, and resources can be efficiently used.

This system is composed of a key verification method (client key holding method) that belongs to a new concept consensus algorithm which is not related to authentication, verification operation, block generation method of super node, and role distribution method for each client's transaction request And the smart node participates in negotiation between the smart nodes), and the information of the formed block chain is transmitted by the block chain digest transmission protocol in the form of the megablock to the second digest trans Form.

In this way, it is possible to add the process of confirming the correspondence between the existing block chain and the variable megablock, so that the dual security system can be applied, thereby minimizing the loss of the user and maximizing the blocking efficiency from the malicious approach .

In addition, this system is a new attempt that deviates from the existing framework, which relies entirely on the first-generated block chain. As the block size increases, the amount of information accumulated and the amount of accumulated information increases, And the burden concentrated on the block chain in the block chain digest transmission protocol can be reduced by the processing method such as distribution and sharing, resulting in a benefit that the block chain is relatively lightened .

The work proof method was to substitute the size of the decision right of the consensus of each node in a way that directly proportional to the hash power for each node out of the condition of general consensus participation trapped in some existing formal framework. (Mining Machine Purchasing Cost) and Maintenance Cost (Power Usage Cost, Maintenance Cost, etc.) are included in the system. However, in the key verification system of the present system, the occurrence factor of the cost is minimized, It is a very environmentally friendly way.

In addition, since the method of receiving the compensation corresponding to the equity (Coin / Stake) in the equity stipulation method is that there is a disadvantage that the more the stake, the more the compensation for the rich and the poor can be deepened. On the other hand, And the system contributes to the system according to the time and frequency of participating in the network active state. Thus, it is a fair compensation system compared to the existing system.

As described above, the present invention is not limited to the above-described specific preferred embodiments, and various changes and modifications may be made by those skilled in the art without departing from the scope of the present invention as claimed in the claims. And such variations are within the scope of the present invention.
