Anti-quantum computing asymmetric key management method and system based on asymmetric key pool and implicit certificate

Abstract

The invention relates to an anti-quantum computing asymmetric key management method and a system based on an asymmetric key pool and an implicit certificate. According to the method and the system, the secret key management method based on the implicit certificate is improved, and the asymmetric secret key pool is used for ensuring that the acquisition and updating of the asymmetric secret key canonly be obtained by the client with the asymmetric secret key pool and cannot be obtained by any other people. Because the asymmetric secret keys are not disclosed, and the secret keys cannot be obtained in the disclosed user information, the asymmetric secret key using mode has the characteristic of quantum computing resistance.

Description

technical field [0001] The present application relates to the technical field of secure communication, in particular to a quantum computing-resistant asymmetric key management method and system based on an asymmetric key pool and an implicit certificate. Background technique [0002] The rapid development of the Internet has brought great convenience to people's life and work. People can send and receive e-mails, make phone calls, do online shopping, and bank transfers while sitting at home. At the same time, network information security has gradually become a potentially huge problem. Generally speaking, network information faces the following security risks: network information theft, information tampering, attackers forging information, malicious damage, etc. [0003] Among them, identity authentication is one of the means to protect people's network information. Identity authentication, also known as "identity verification" or "identity identification", refers to the p...

Problems solved by technology

[0011] 1. The existing key management scheme based on the symmetric key pool, the symmetric key pool is used between the server and the client, and its capacity is huge, which puts pressure on the key storage of the server;

[0012] 2. Existing key management schemes based on symmetric key pools. Due to the huge capacity of symmetric key pool keys, the server has to encrypt and store the keys in ordinary storage media such as hard disks, and cannot store the keys in the server’s encryption. inside the key fob;

[0013] 3. The existing scheme of key management based on symmetric key pool, due to the huge capacity of symmetric key pool key, causes troubles for online key update
