Distributed network node authentication method based on chip

Abstract

The technical scheme of the invention discloses a distributed network node authentication method based on an encryption chip. The method comprises the following steps: a first node and a second node respectively generate a public and private key pair and a random number; the first node and the second node exchange random numbers and public key information with each other; the first node receives the second random number, processes the second random number by using the first private key and the second public key to obtain a first encrypted signature and transmits the first encrypted signature to the second node; the first node receives the second encrypted signature by using the first private key and the second public key to decrypt and obtain verification information; and if the verification results of the first node and the second node are consistent, the encrypted hardware number of the current node is bound with the current node to complete node verification. According to the distributed network node authentication method and system based on the chip provided by the invention, a hardware random number and information encryption combined method is adopted, so that the security ofidentity authentication information between different nodes in a distributed network is greatly improved.

Description

technical field [0001] The invention relates to the technical field of distributed network node security authentication, in particular to a chip-based distributed network node authentication method. Background technique [0002] Distributed technology is a technology that combines distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies, and is widely used in various industries such as finance and e-commerce. In the distributed network system, in the process of chaining and querying data blocks, it is often necessary to transfer some data in the distributed network system, such as chaining information, query requests, etc. Since the blockchain is a decentralized distributed database, it does not rely on any centralized server, but consists of tens of thousands of "small servers" and "nodes". The more and more nodes are distributed, the more decentralized the distributed network will be, and the safer an...

Problems solved by technology

However, most of the random numbers in the distributed network are simulated by computer software programs, one cannot achieve true randomness, and the other is easy to be cracked

In the symmetric key authentication method, the symmetric key is uniformly issued by the authentication management center, and there are many participating links, which can easily lead to the key information being cracked.
