Anti-quantum computing RFID authentication method and system based on symmetric key pool and online and offline signatures

Abstract

The invention relates to an anti-quantum computing RFID authentication method and system based on a symmetric key pool and online and offline signatures. The parties comprise an authentication party and a request party which interact with each other in an RFID mode, wherein each party is configured with a key fob; algorithm parameters are stored in the key fob; an identity label and a public key of the request party, a private key corresponding to the public key, a temporary public key, a temporary private key corresponding to the temporary public key and a symmetric key unit are stored in a key fob of the request party; a symmetric key pair is stored in the symmetric key unit, and the symmetric key pair comprises a first symmetric key, a second symmetric key and a key pointer address; andthe key pointer address is used for extracting a related symmetric key unit from a symmetric key pool. By adopting the anti-quantum computing RFID authentication method, the storage cost in the key fob of the request party can be reduced, and the security in the authentication interaction process of the request party and the request party can be improved.

Description

technical field [0001] The present application relates to the technical field of secure communication, in particular to a quantum computing-resistant RFID authentication method and system based on a symmetric key pool and online and offline signatures. 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...

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 Signature, making the signature's anti-repudiation ability insufficient

[0006] 2. The existing identity authentication scheme based on the asymmetric key pool, because the asymmetric key cannot be used publicly, it must be encrypted to resist quantum computing, so the entire identity authentication process needs to use encryption algorithms for asymmetric keys or Signature for encryption protection

Therefore, this method increases the amount of calculation for RFID devices, which may slow down the identification process; for battery-powered RFID, it will accelerate the consumption of power
