In order to solve the security and identifying dead circulation problems in RFID systems which exist tags identification,a RFID group authentication protocol with anti-collision（GIA）is proposed in this paper.In the identification process,GIA protocol uses pseudonyms for identified anti-collision,which prevents the disclosure of tag sensitive information.During the authentication process,GIA protocol only uses a pseudo-random number generator to achieve mutual authentication between the reader and the tag and to solve the security issues such as the man in the middle attack,forward security,replay attack and cloning attack,etc.as well as meeting the requirements of low-cost tags.The provable security model is used to prove that GIA has met the security goals.Compared with currently existing relevant research,GIA has better performance in storage overhead,computation load and communication overhead. 无线射频识别 群认证 防冲突 RFID（radio frequency identification） group authentication anti-collision 10.14188/j.1671-8836.2014.05.013 TP391.44 国家自然科学基金资助项目（61272033） 2014-05-01 2021-04-01 5 60
