Abstract: 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 RFID 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.
