Problems solved by technology

However, the data processing capacity of the public key pool authority is limited. In extreme cases, network problems may occur and the communication function of the public key pool authority may be lost. In addition, when the attacker obtains the real network location of the public key pool authority, Can launch denial of service attacks
Therefore, the centralized design of the public key pool authority is the weakness that leads to systemic risks in the entire system

Abstract

The invention discloses a method and system for updating an anti-quantum computing public key pool based on a consortium chain. The nodes of the consortium chain include a user client and a consortium chain server, and both the user client and the consortium chain server are equipped with a key card , the private key and the public key pool are stored in the key card, the public key pool contains the same number of public key pool units as the number of nodes in the alliance chain, and each public key pool unit stores a public key corresponding to the node. In the process of the user passing the public key and signature information to other members, the invention uses the public key in the public key pool as an offset to encrypt the public key and signature information, and the quantum computer cannot decrypt the public key and signature information. out the private key.

Description

technical field [0001] This application relates to the field of consortium chains, in particular to a method and system for updating a quantum-resistant public key pool based on consortium chains. Background technique [0002] The wide application of the Internet enables people who do not know each other far away in every corner of the world to quickly exchange information and share information resources. In the process of exchanging, people don't always hope that the information they send will be known by everyone. Due to various considerations, the person who sends the message only hopes that the information sent by him will be known by the people related to it. For this reason, people use passwords to encrypt the information they send, and only people with the same password can decrypt the information. In addition, in an era when the world is connected in such an extensive network world through the Internet, for the purpose of global e-commerce and electronic trade, peop...
