Quantum Communication Server Secure Communication Method and System Based on Asymmetric Key Pool and Implicit Certificate

Abstract

This application relates to a quantum communication server-side secure communication method and system based on an asymmetric key pool and an implicit certificate. This patent uses an implicit certificate to implicitly verify the public key’s security for the implicit certificate-based secure communication method. Reliability is proved, and asymmetric keys and digital signatures are used to prove the user's identity. Both the sender and the sender of the confidential communication can clearly identify the other party's identity, and no one else can interfere or counterfeit the confidential communication. Since none of the asymmetric keys are disclosed, and the keys cannot be obtained from public user information, the asymmetric key usage method in this paper has the characteristics of anti-quantum computing.

Description

technical field [0001] The present application relates to the technical field of secure communication, in particular to a quantum communication server-side secure communication 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 sit at home to send and receive e-mails, make phone calls, conduct online shopping, bank transfers and other activities through the Internet. At the same time, network information security has gradually become a potential huge problem. Generally speaking, network information faces the following security risks: network information is stolen, information is tampered with, attackers fake information, malicious damage, etc. [0003] Among them, confidential communication is one of the means to protect people's network information. It is generally realized by cryptographic encryption. Before en...

Problems solved by technology

[0010] 1. The existing scheme for secure communication based on a symmetric key pool uses a symmetric key pool between the server and the client, which has a huge capacity and puts pressure on the key storage of the server;

[0011] 2. Existing schemes for secure communication 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 on the server. card;

[0012] 3. The existing scheme of secure communication based on the symmetric key pool, due to the huge key capacity of the symmetric key pool, causes troubles to the online update of the key
