Equipment identifier construction method and device based on PoW algorithm and computer readable storage medium

Abstract

The invention discloses an equipment identifier construction method and device based on a PoW algorithm and a computer readable storage medium. The method comprises the steps that S10, constructing PeerInfo, generating an asymmetrically encrypted key pair, wherein the asymmetrically encrypted key pair comprises a public key (Public Key) and a private key (Private Key); S20, calculating an invariable part in the PeerInfo according to an information digest algorithm to obtain a PeerID; S30, after receiving a request of the incoming node device to join the P2P network, verifying the node device requesting to join the P2P network according to the PeerID of the node device requesting to join the P2P network; S40, after the node equipment requesting to join the P2P network passes the verification, adding the node equipment passing the verification into the P2P network; and step S50, enabling the device already joining the P2P network to continuously execute the PoW process locally. The PeerID can be constructed without a central server, and the problem of masquerading can be solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a PoW algorithm-based device identification construction method, device and computer-readable storage medium. Background technique [0002] Identity authentication can also be called identity verification or authentication, which refers to the process of confirming the identity of the operator in the computer and computer network system, so as to determine whether the user has access and use rights to certain resources, and then make the computer and network system The access policy can be implemented reliably and effectively, preventing attackers from posing as legitimate users to gain access to resources, and ensuring the security of the system and data. [0003] Usually, the integrity of data depends on trust in the system center or third-party entities, such as the master node of the system, the central database, the person in charge of the system, the administrator...

AI Technical Summary

Problems solved by technology

In this data protection method based on public key infrastructure, its highly centralized certificate authority will cause the following problems: First, when problems arise during the communication process, the certificate authority cannot make corresponding countermeasures , the two sides of the communication will not be able to solve this problem, leading to the end of the problem; second, once the certificate authority is attacked, the network system will be greatly damaged; third, it is vulnerable to distributed denial of service (Distributed Denial of Service) Service, DDoS) attack
