摘　　要：RFID的普遍应用引起了安全问题,在众多的RFID安全解决方案中重加密技术具有很多优点。该文描述重加密的优势,介绍重加密在RFID安全应用中的发展现状,提出了重加密在RFID中的应用模型和安全要求,指出重加密存在的弱点,对重加密间隔内的跟踪问题给出了解决对策,探讨了抗置换攻击问题。The prevailing of RFID arouses the security concern. Re-encryption is an approach with many advantages among approaches for RFID security. This paper describes the advantage of re-encryption and introduces the development of the application of re-encryption in RF[D security. It promotes an application model for re-encryption in RFID security and security requirement, and points out that re-encryption has its short points. As to the tracking problem between re-encryption, it promotes the solution, and discusses the solution for the swapping attack in re-encryption system.
