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 an anti-quantum computing public key pool updating method and system based on an alliance chain. Nodes of the alliance chain comprise a user client and an alliance chain server, the user client and the alliance chain server are configured with key cards, private keys and public key pools are stored in the key cards, each public key pool comprises public key pool units of which the number is the same as that of the nodes of the alliance chain, and a public key corresponding to each node is stored in each public key pool unit. In the process that the user transmits the public key and the signature information to other members, the public key in the public key pool is used as the offset to encrypt the public key and the signature information, and the quantum computer cannot crack the private key through the public key and the signature information.

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...
