Description

System and Method for Packet Bypass Transmission by Blockchain Network and Distributed Node }

The present invention relates to a transmission system and method for bypassing packets using nodes participating in a blockchain network.

Blockchain is a database technology using distributed nodes, and has the characteristic of inter-node communication. Blockchain is a distributed node, designed to respond immediately to tampering attacks on data. Blockchain uses a consensus algorithm to enable distributed consensus among nodes that cannot be trusted with each other in a global network. In order to add a block, that is, information to the block chain, the node that creates the block (hereafter the miner) must verify the validity of the block to be added. Although the verification method differs depending on the consensus algorithm, it has in common that it uses computational power fundamentally. Several miners use their own computational power to verify and create one block, but in the end, the meaningful computational power is the computational power of the miner who created the block registered in the block chain. The computational power of the remaining miners is ultimately wasted.

Many users use a VPN (Virtual Private Network) service for stronger security and free information access. A VPN is a virtual private network that uses a tunneling protocol to communicate and protect information. However, users' personal information may be exposed on the VPN service provider's server, and there is no data available to general users about what is happening on the server. That is, the user uses the service based on trust in the service provider.

As in the case of 'Hola VPN' selling users' personal information without permission, depending on the service provider, the user's personal information is protected or exposed to a dangerous situation.

Tor Browser is a technology that triples bypassing packets through a virtual circuit connection between a user and a distributed node. The distributed node used to run the Tor browser has a low participation rate because it is operated through voluntary participation and is therefore very slow. Internet speeds slowed by triple detour of packets are exacerbated by a small number of distributed nodes.

The packet detour method by the block chain network and the host according to the embodiment of the present invention is characterized by the packet detour by the computing power of the distributed node operating the block chain and the virtual line connection.

This information is generated and propagated by relay nodes, and all miners have this information. If a specific CHD is not used for a certain period of time, it is automatically destroyed.

Packet bypass starts with a user's connection request. The relay node reads the user's connection request and helps connect with the host. The process of connecting a user to a host is called a network connection. Internet access becomes possible as soon as the user's network connection is completed. The user bypasses the packet with a direct connection to the host rather than a direct connection to the web server. At this time, the user and the host prevent packet information from escaping to the outside through the virtual line connection.

Hereinafter, a packet bypass transmission system and method by a blockchain network and distributed nodes according to some embodiments of the present invention will be described.

1 is a diagram showing the configuration of a packet bypass transmission system by a blockchain network and distributed nodes according to an embodiment of the present invention. The packet bypass transmission system shown in FIG. 1 is according to an embodiment, and its components are not limited to the embodiment shown in FIG. 1 , and some components may be added, changed, or deleted as necessary.

As shown in FIG. 1 , the packet bypass transmission system of the present invention includes a distribution node 200 and a relay node 300 .

The distributed node 200 prevents eavesdropping and eavesdropping on transmission/reception-related actions between the user terminal 100 and the server 400 by bypassing the packet through a virtual line connection with the user terminal 100 . At this time, the distributed node 200 forms a blockchain network. And the server 400 may include a web server such as an online shopping mall.

Meanwhile, the distributed node 200 may include a host system unit 210 , a minor system unit 220 , and a voter system unit 230 .

The host system unit 210 includes a plurality of hosts 211, 212, and 213 that process packet detour (hereinafter referred to as 'hosting') by a user's request in a block chain network.

In this case, the host system unit 210 includes a function that enables a virtual line connection using asymmetric key encryption between a user and a host in a block chain network and payment of a host reward. In addition, the host system unit 210 operates in a block chain network, bypasses the user's packet through a virtual line connection by asymmetric key encryption with the user, and enables the compensation payment by the minor system unit 220 . includes

The minor system unit 220 includes a plurality of miners 221, 222, and 223 that process information such as block generation, hosting verification, and host reward payment in a block chain network.

At this time, the minor system unit 220 operates in the block chain network, generates blocks, verifies and broadcasts transactions, and processes information from the host system unit 210 . And the miners are elected by the voter system unit 230 and the like, and are given the right to generate blocks for a certain period of time.

The voter system unit 230 is composed of a plurality of voters 231, 232, and 233 who periodically elect miners and hosts in the blockchain network.

At this time, the voter system unit 230 holds a certain amount of stake or more operating in the block chain network, and performs the host election of the minor system unit 220 and the host system unit 210 through a specific algorithm.

In addition, the relay node 300 allocates a host that processes packet detour (hosting) by a user request in the block chain network, and processes host information storage and the like.

At this time, the relay node 300 operates in the block chain network to store and broadcast the election result of the voter system unit 230 , and a user request for a smooth connection between the user terminal 100 and the host system unit 210 . to process

The operation of the packet bypass transmission system by the blockchain network and the distributed node according to the present invention configured as described above will be described in detail with reference to the accompanying drawings. The same reference numerals as in FIG. 1 refer to the same members performing the same functions.

2 is a flowchart illustrating a process in which a user connects with a host in a packet bypass transmission system by a blockchain network and distributed nodes.

As shown in FIG. 2 , the user transmits a network connection request signal to the relay node 300 together with information such as the country belonging to the host to which the user wishes to connect and his/her public key ( S101 ).

Then, the relay node 300 selects a suitable host by analyzing the host information stored in the host system unit 210 based on the transmitted network connection request signal ( S102 ). Then, the relay node 300 transmits the IP address of the selected host to the user (S103).

In addition, the relay node 300 generates CHD (Client and Host Data), which is data that bundles the public key information of the user and the host (S104), and broadcasts the generated CHD to the blockchain network (S105).

The user executes ARP (Address Resolution Protocol) in the block chain network using the IP address of the host received from the relay node 300 through the user terminal 100 to receive information including the MAC address of the host (S106) .

Then, the user connects the user terminal 100 with the host by unicasting to the block chain network using the received information including the MAC address of the host (S107).

3 is a flowchart illustrating a process in which a user communicates with a packet detour server through a host in a packet detour transmission system by a blockchain network and distributed nodes.

As illustrated in FIG. 3 , the user transmits a request signal to the host system unit 210 to attempt a virtual line connection ( S201 ). In this case, the host available to the user is determined, which is contained in the CHD information of the relay node 300 .

Then, when the virtual line connection is established (S202), the user transfers the user's public key for encrypted communication between the user and the host to the host system unit 210 to request an exchange (S203).

The host system unit 210 verifies that it is the same node by comparing the user's public key delivered from the user with the CHD information broadcast by the relay node (S204).

As a result of the verification (S204), if it is confirmed that the user is not the correct user (S205), the information transmitted from the user is discarded (S206).

And, when the verification result 204, when it is confirmed as the correct user (S205), the virtual line connection is accepted and the public key of the host is delivered to the user terminal 100, thereby indicating to the user that the virtual line connection between the host and the user has been completed. Contact (S207). In this case, the completion of the virtual line connection means that the network connection of the user terminal 100 is completed. And the completion of the network connection means that the Internet access of the user terminal 100 is allowed.

The user uses the user terminal 100 to encrypt a packet to be transmitted to the (web) server 400 with the public key of the host, and transmits the encrypted packet to the host system 210 (S208).

Then, the host system unit 210 decrypts the encrypted packet received from the user terminal 100 with the private key of the host to directly connect with the (web) server 400 (S209). At this time, the address information of the packet contains the host's own address, and the packet input from the server 400 is returned to the host itself.

Accordingly, the host encrypts the packet input from the server 400 again with the user's public key and transmits it to the user terminal 100 (S210).

The user decrypts the packet delivered from the host with his/her private key and reads it (S220).

As such, in the user's (web) server 400 connection, the detour proceeds through the host, which is the intermediate node 400 . Transmission and reception between the host and the user is always done through a virtual circuit connection.

4 is a flowchart illustrating a process of generating a coinbase TX (Transaction) for verification of a host's operation and payment of a reward in a packet bypass transmission system by a blockchain network and distributed nodes.

As shown in FIG. 4 , the user terminal 100 and the host generate a key array by binding their own public key and a counterpart public key at the same time as transmitting and receiving an encryption packet. A user's key arrangement and a host's key arrangement are generated (S301).

Then, the generated user's key arrangement and the host's key arrangement are broadcast to the block chain network (S302). In this case, the user terminal 100 and the host compare their public keys and time stamps in one transmission/reception process, and rearrange the key arrangement according to time to form them.

The minor system unit 220 and the relay node 300 verify the broadcast contents of the user's key arrangement and the host's key arrangement (S303). In this case, the verification of the key arrangement may be verified as whether the minor system unit 220 and the relay node 300 possess the same key arrangement by comparing the time stamp with the public key information. This is done through the average value of the timestamps of the two key arrays and the public key of the host.

On the other hand, the minor system unit 220 and the relay node 300 compare key arrays when receiving the key array before Coinbase TX generation, and include in Coinbase TX when receiving the key array after Coinbase TX generation. It is possible to determine whether or not to hold the host by comparing the average value of the timestamp with the wallet address of the host.

As a result of the verification (S303), if the minor system unit 220 and the relay node 300 have the same key arrangement, the input key arrangement is discarded and a transaction is not generated (S304).

And, if the verification result (S303) and the minor system unit 220 and the relay node 300 do not have the same key arrangement, the time stamps are compared and the two key arrangements are rearranged in chronological order (S305).

Then, the public key used for the key arrangement and the CHD information broadcast by the relay node 300 are compared to check whether they are the same node (S306).

And if it is confirmed that the node is not the same as the result of the check (S306), the key arrangement is destroyed and a transaction is not generated (S304).

In addition, if it is confirmed as the same node as the result of the check (S306), the minor system unit 220 generates a Coinbase TX (Transaction) based on the content of the checked key arrangement, and stores it in a block (S308). At this time, the minor system unit 220 and the relay node 300 identify the transaction as the average value of the timestamp information of the two key arrays, and pay the reward using the wallet address matching the host's public key. . The wallet address must be the host's wallet address, and the reward is paid with the created Coinbase TX (Transaction).

When the coinbase TX generation is completed, the minor system unit 220 and the relay node 300 register the transaction in the block inclusion queue and simultaneously broadcast the transaction to the block chain network (S309).

5 is a flowchart illustrating a process of validating Coinbase TX in a packet bypass transmission system by a blockchain network and distributed nodes, and receiving qualifications for transactions to be included in blocks.

As shown in FIG. 5 , the minor system unit 220 and the relay node 300 receive broadcast transaction information (Coinbase TX) (S401).

Then, it is determined whether the broadcast received transaction (Coinbase TX) is retained (S402).

As a result of the determination (S402), if the received transaction (Coinbase TX) is not held, that is, if it is a new transaction, the transaction (Coinbase TX) is added to the block inclusion queue (S403), and the number of transaction propagation starts counting (S404).

Meanwhile, as a result of the determination (S402), if the received transaction is a transaction already held, the number of transaction propagation is increased (S405).

Next, it is compared whether the number of transaction propagation is equal to or greater than a predetermined value (S406). At this time, if the same transaction is continuously transmitted and the number of propagation exceeds a certain value, it is entitled to be included in the block.

Accordingly, when the number of propagation times as a result of the comparison (S406) is equal to or greater than a predetermined value, the transaction information (Coinbase TX) is included in the block by the minor system unit 220 having block generation authority (S407).

In this way, when a transaction of the same information is broadcast more than a certain number of times, the transaction is judged to be valid and entitled to be included in the block chain.

As described above, the present invention has been described with reference to the illustrated drawings, but the present invention is not limited by the embodiments and drawings disclosed in the present specification. It is obvious that variations can be made. In addition, although the effects according to the configuration of the present invention are not explicitly described and described while describing the embodiments of the present invention, it is natural that the effects predictable by the configuration should also be recognized.

destroying the key arrangement of the user terminal and the key arrangement of the plurality of hosts if the minor system unit and the relay node do not have the same key arrangement as a result of the verification;
as a result of the verification, if the minor system unit and the relay node have the same key arrangement, comparing timestamps and rearranging the key arrangement of the user terminal and the key arrangement of the plurality of hosts in chronological order;
comparing the public key used for the key arrangement of the user terminal and the key arrangement of the plurality of hosts with the CHD broadcast by the relay node, and confirming whether the node is the same;
destroying the key arrangement of the user terminal and the key arrangement of the plurality of hosts when it is confirmed that the node is not the same node as a result of the check;
generating a Coinbase TX (Transaction) through the minor system unit based on the contents of the key arrangement of the user terminal and the key arrangement of the plurality of hosts if the same node is identified as a result of the check, and storing in a block; and
and registering a transaction in a block inclusion queue through the minor system unit and the relay node, and broadcasting the transaction to the block chain network.
13. The method of claim 12,
In the step of generating the key arrangement of the user terminal and the key arrangement of the plurality of hosts, the user terminal and the plurality of hosts compare their public keys and time stamps in one transmission/reception process in time. A packet bypass transmission method that rearranges the key array to match.
13. The method of claim 12,
The step of verifying the key arrangement of the user terminal and the key arrangement of the plurality of hosts includes:
Comprising the step of verifying whether the same key array is retained by comparing the timestamp and public key information,
The key arrangement of the user terminal and the key arrangement of the plurality of hosts include a time stamp average value of the key arrangement and a public key of the plurality of hosts.
15. The method of claim 14,
The step of verifying the key arrangement of the user terminal and the key arrangement of the plurality of hosts includes:
Comparing the key arrays when receiving the key array before Coinbase TX generation; and
and comparing the average timestamp value with the wallet address of the host included in the Coinbase TX when receiving the key array after the Coinbase TX is generated.
13. The method of claim 12,
The step of creating the Coinbase TX (Transaction) and storing it in a block is
identifying a transaction with an average value of timestamp information included in the key arrangement of the user terminal and the key arrangement of the plurality of hosts; and
and paying a reward using a wallet address matching the host public key of the identified transaction.
13. The method of claim 12,
The step (C) is
judging whether or not the coinbase TX broadcast through broadcasting to the minor system unit and the relay node is possessed;
as a result of the determination, if the Coinbase TX is not possessed, adding the Coinbase TX to a block inclusion queue and starting to count the number of times of transaction propagation;
As a result of the determination, if the Coinbase TX is already in possession, increasing the number of transaction propagation; and
When the number of transaction propagation is greater than or equal to a certain amount, the method further comprising the step of including Coinbase TX in the block by the minor system unit.
