Anti-quantum computing RFID authentication method and system based on asymmetric key pool and secondary remainder

Abstract

The invention relates to an anti-quantum computing RFID authentication method and system based on an asymmetric key pool and secondary remainder. The participants comprise an authentication party anda request party which interact in an RFID mode. Each participant is configured with a key fob; wherein an identity label, a true random number, a public key and a secret key pointer address of the requester are stored in a secret key card of the requester; wherein the key pointer address is used for extracting a corresponding asymmetric key unit from the asymmetric key pool, and by adopting the method, the storage cost in a key card of a requester can be reduced, and the safety in an authentication interaction process of the requester and the requester can be improved.

Description

technical field [0001] This application relates to the technical field of designing secure communication, in particular to an anti-quantum computing RFID authentication method and system based on an asymmetric key pool and quadratic remainder. Background technique [0002] Radio Frequency Identification (RFID) is the abbreviation of Radio Frequency Identification. RFID radio frequency identification technology is an earlier technology. In the 1950s, the theory of RFID radio frequency identification technology was developed. In the 1970s, some earlier RFID applications appeared, and RFID gradually entered the commercial stage. Since the 1980s, with the increasing attention to the standardization of RFID technology, RFID products have been more and more widely used. The principle is to conduct non-contact data communication between the reader and the tag to achieve the purpose of identifying the target. The application of RFID is very extensive. At present, typical applicat...

Problems solved by technology

[0005] 1. The existing identity authentication scheme 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, and is not suitable for applications with a very small storage capacity. RFID device

Moreover, the security degree of the symmetric key algorithm for identification is not high enough: on the one hand, using the same symmetric key multiple times may lead to insufficient security of the key or even being cracked; on the other hand, any party with the symmetric key can make
