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

Abstract

This application relates to an anti-quantum computing RFID authentication method and system based on an asymmetric key pool and quadratic remainder. The participating parties include the authentication party and the requesting party that interact through RFID, and each of the participating parties is configured with Key card, the key card of the requesting party stores its own identity, true random number, public key and key pointer address, and the key pointer address is used to extract the corresponding key from the asymmetric key pool The asymmetric key unit adopts the method, which can reduce the storage cost in the key card of the requesting party, and improve the security in the authentication interaction process between the two parties.

Description

Technical field [0001] The present application relates to the field of design security communication, and in particular, to a non-symmetric key pool and a secondary remaining anti-quantum computational RFID authentication method and system. Background technique [0002] RF recognition (RFID) is an abbreviation for Radio Frequency Identification. RFID RFIT is an earlier technology. In the 1950s, the theory of RFID RF identification technology was developed. In the 1970s, some earlier RFID applications occurred, and RFID gradually entered the business stage. Since the 1980s, with the renewal of RFID technology, RFID products are increasingly widely adopted. The principle is a non-touchd data communication between the reader and the tag to achieve the purpose of identifying the target. RFID is very extensive, currently typical application with animal wafers, automotive wafers, access control, parking control, production line automation, material management.

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
