Anti-quantum computing access control method and system based on disposable asymmetric key pair and movable identity recognition device

Abstract

The invention relates to an anti-quantum computing access control method and system based on a disposable asymmetric secret key pair and a movable identity recognition device. A secret key card used in the method is independent hardware isolation equipment. The public key, the private key and other related parameters are all stored in the data security area in the key card, so that the possibilityof stealing the key by malicious software or malicious operation is greatly reduced, and the key cannot be acquired and cracked by the quantum computer. Since the transmission of public and private keys and algorithm parameters is not involved in the classical network, the risk that the asymmetric key is cracked is very low.

Description

technical field [0001] The present application relates to the technical field of secure communication, in particular to a quantum computing-resistant access control method and system based on a one-time asymmetric key pair and a movable identification device. 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, identity authentication is one of the means to protect people's network information. Identity authentication is also known as "identity verificati...

If lost, it may cause ID information leakage

If the ID is recorded at multiple access control identification devices, ID tracking can be realized, which is a serious information leakage in some application scenarios;

[0011] 2. Issue a symmetric key to the mobile identification device, because the symmetric key cannot be used for reliable digital signatures, so it is not good for identification;

[0012] 3. Issue an asymmetric key pair to the mobile identification device, and use the private key to perform digital signatures. This method cannot resist quantum computing because the public key needs to be disclosed when verifying the digital signature;

[0013] 4. Issuing the private key of the asymmetric key to the mobile identification device and storing the public key in the server can resist quantum computing. identification, so the random number of the ID or public key pointer must be disclosed, resulting in leakage of user information
