Communication method between blockchain nodes

Short answer question

Describe the typical architecture of a blockchain alliance network. A blockchain alliance network usually consists of service nodes and consensus nodes. Service nodes are responsible for processing specific business and sending business data to consensus nodes. Consensus nodes are responsible for verifying and confirming the data sent by service nodes.

In a blockchain alliance network, why do we need to pay attention to data security between service nodes? Because the business data stored by service nodes may contain user privacy information. If there is a lack of effective security mechanism, unauthorized service nodes may steal sensitive data stored by other service nodes, resulting in user privacy leakage.

What problems does the existing TLS protocol have in terms of communication security between blockchain nodes? The TLS protocol can only verify the authenticity of the node identity, and cannot restrict the establishment of connections between nodes that have passed authentication but have no service relationship. In other words, even if both nodes have valid certificates, if there is no pre-defined service relationship between them, the TLS protocol cannot prevent them from establishing a communication connection, which lays a hidden danger for data leakage.

How does the method proposed in this patent solve the shortcomings of the existing TLS protocol? Based on the TLS protocol, this patent method introduces the concept of "mapping relationship" between nodes. A communication connection is allowed to be established only when there is a pre-defined mapping relationship between the two nodes requesting to establish a connection. This mechanism effectively prevents data exchange between unauthorized nodes and improves data security.

What is the "mapping relationship" between nodes? The "mapping relationship" between nodes refers to a service relationship between nodes participating in the same service. For example, if two service nodes participate in the same business process, there is a mapping relationship between them. There is also a mapping relationship between the consensus node and the service node that verifies it.

How does the method proposed in this patent verify the "mapping relationship" between nodes? In the process of establishing a connection, the nodes exchange certificates containing their own identity information. The certificate contains one or more identifiers, such as a node identifier, a network identifier, a service identifier, or a group identifier. The nodes can determine whether there is a mapping relationship between each other by checking the identifiers in the other party's certificate.

In addition to the node identifier, what other information can be included in the certificate? In addition to the node identifier, the certificate can also contain a network identifier, a service identifier, or a group identifier. This information can help nodes more accurately determine whether there is a mapping relationship between each other.

How does the method proposed in this patent achieve two-way verification? When a node receives a connection request from another node, it sends a verification request to the other party. The connection will only be established when the other node also confirms that there is a mapping relationship between them.

What are the advantages of the method proposed in this patent over the existing technology? This patented method effectively prevents data exchange between unauthorized nodes by limiting the communication connection between nodes, thereby improving data security, especially the security of user privacy data.

What types of blockchain networks are suitable for the method proposed in this patent? The method proposed in this patent is particularly suitable for blockchain alliance networks, and can effectively improve the security of communication between nodes in alliance networks.

Glossary

Term Definition Blockchain A distributed ledger technology used to record and verify transactions. Node Participants in a blockchain network can be service nodes or consensus nodes. Service nodes are nodes responsible for processing specific businesses, such as servers of banks, enterprises and other institutions. Consensus nodes are nodes responsible for verifying and confirming consensus on transaction data sent by service nodes. Mapping relationship A service relationship between nodes participating in the same service. For example, if two service nodes participate in the same business process, there is a mapping relationship between them. Certificate A digital certificate issued by a trusted authority to prove the authenticity of the node identity. Identifier A string or number used to uniquely identify a node, network, service, or group. Two-way authentication The process of mutual authentication between the two parties in communication can effectively improve the security of communication. TLS protocol A network security protocol used to provide a secure communication channel between two computers.
