NFC SECURITY AUTHENTICATION ALGORITHM BASED ON CHINESE REMAINDER THEOREM
Aiming at the security problems in the application of near-field communication technology,this paper presents an algorithm based on Chinese remainder theorem(CRT).The algorithm used CRT to encrypt the transmitted information.CRT was based on the decomposition problem of large prime numbers in mathematics,which made it impossible for the attacker to crack.Random numbers were mixed into all information encryption processes to ensure the freshness of the message.When updating the information,the algorithm used pseudo-random function calculation,because of the unidirectionality of the pseudo-random function,it was impossible for the attacker to analyze useful privacy information.The security analysis between different algorithms shows that this algorithm can resist replay attacks,asynchronous attacks and other attacks.The performance and simulation experiments show that this algorithm has lower computational complexity and time complexity than other algorithms.
