Radio frequency identification system safety certification and key agreement method

Abstract

The invention discloses a radio frequency identification system safety certification and key agreement method. According to the radio frequency identification system safety certification and key agreement method, transmission of public values of the two communication parties is simplified, the public values are transmitted through a certification server, influences on the safety performance are avoided, and therefore even through the server is broken into, it is certain that following certification can not be passed. In the certification process, three-round communication and seven-step operation are required to be executed to generate a session key, and compared with same-class methods, the radio frequency identification system safety certification and key agreement method has the advantage that efficiency is greatly improved. The radio frequency identification system safety certification and key agreement method has the advantages of being safe, low in storage cost and communication cost, novel, easy to implement and the like. By means of the radio frequency identification system safety certification and key agreement method, server leakage attack, midwayer attack, off-line guessing attack and not-detectable on-line guessing attack can be effectively defended, meanwhile, a bidirectional certification session key with high safety performance and forward safety performance are provided, and the radio frequency identification system safety certification and key agreement method is quite suitable for RFID application systems which must provide privacy protection.

Description

technical field [0001] The invention belongs to the technical field of information security, in particular to a security authentication and key negotiation method based on a radio frequency identification system. Background technique [0002] Radio Frequency Identification (RFID) is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. The RFID system generally consists of three parts: RFID tags, RFID readers and background servers. The tags and readers communicate in a non-contact manner. The emergence of RFID technology has solved the problem of automatic data identification, processing information more quickly and accurately, reducing manual intervention, avoiding tedious manual input and other processes, thereby reducing production costs, and radio frequency identific...

AI Technical Summary

Problems solved by technology

The emergence of RFID technology has solved the problem of automatic data identification, processing information more quickly and accurately, reducing manual intervention, avoiding tedious manual input and other processes, thereby reducing production costs, and radio frequency identification has been widely used in China. In the supply chain of foreign companies, it is used in various industries. However, due to the existence of information security problems, RFID applications have not yet been popularized in the most important key tasks.
