Anti-quantum-computing key negotiation method based on asymmetric key pools

Abstract

The invention relates to an anti-quantum-computing key negotiation method based on asymmetric key pools. The method includes a group. The group includes a plurality of use ends. The key pools are stored in quantum key cards configured for all the use ends, and include private key pools of the current parties and public key pools of the other members of the group. Equal negotiation keys are obtained through interaction of parameters of all the parties and the key pools of the current parties, and then key negotiation of every two terminals is realized. The quantum key card are independent hardware isolation equipment, greatly reduces possibility of stealing the keys by malicious software or malicious operations, and also cannot be obtained and cracked by quantum computers; and in the group,an asymmetric key exchange manner is adopted to realize key negotiation between objects, key sharing of two communication parties is realized, other objects cannot get corresponding shared keys, andcommunication security of the two communication parties in the group is guaranteed.

Description

technical field [0001] The invention relates to a public key cryptosystem and an asymmetric key pool technology, and specifically relates to the key exchange algorithm. The present invention is to realize the key exchange technology between communication parties in a group. 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] At present, the key technology to ensure the security of network information is cryptography. In the field of cryptography today, there are mai...

Problems solved by technology

[0007] However, with the development of quantum computers, the classical asymmetric key encryption algorithm will no longer be safe. Regardless of encryption and decryption or key exchange methods, quantum computers can obtain private keys through public key calculations. Therefore, the commonly used asymmetric keys will be Become Vulnerable in the Quantum Era
