RFID communication security mechanism established based on dynamic randomization DRNTRU public key encryption system

Abstract

The invention discloses an RFID communication safety mechanism which is established by a public key encrypting system on the base of dynamic randomization DRNTRU (Dynamic, Randomized Number Theory Research Unit). The RFID communication safety mechanism which is established by a public key encrypting system based on the dynamic randomization DRNTRU can not only effectively solve the safety problemof the RFID system. The method is novel, simple and easy to realize, does not need to fully search secret keys and TID (tag identifier) of, does not need secret key synchronization, only needs single-direction authentication and is suitable for the RFID system having limited resource and requiring high-speed responding.

Description

technical field [0001] The invention belongs to the technical field of communication, and is particularly suitable for the identification technology of radio frequency tags. Background technique [0002] With the widespread application of RFID (Radio Frequency Identification), the security issues of RFID systems are becoming more and more prominent. The main security issues in RFID systems include confidentiality, traffic analysis and traceability, and personal privacy leakage. These issues have been seriously It hinders the further development of RFID and becomes one of the key problems to be solved urgently in the development of RFID system. Therefore, it has also attracted the attention and investment of many network security scholars in the industry, and various solutions and strategies have been proposed, such as using hash functions, symmetric keys, etc. The system requires the server to exhaustively search for tags in the back-end database. The identification code TI...

Problems solved by technology

Therefore, it has also attracted the attention and investment of many network security scholars in the industry, and various solutions and strategies have been proposed, such as using hash functions, symmetric keys, etc. The system requires the server to exhaustively search for tags in the back-end database. The identification code TID and key of the tag, some systems need the key synchronization between the server and the tag, and the algorithm to maintain the key synchronization between the server and the tag is extremely complicated and difficult to implement, so it will consume a lot of resources of the system, such as execution time and Storage space, not suitable for RFID systems that require high-speed response and only have limited resources

So far, the industry has still failed to propose a safe, efficient, practical, and low-cost solution suitable for RFID system communication security issues
