【Abstract】 In view of the security vulnerabilities such as backward privacy disclosure, violence cracking and so on in the existing RFID tag ownership transfer applications, an improved RFID label ownership transfer protocol satisfying backward and non-traceability is designed. Under the lightweight standard, it used the quadratic residue algorithm as the protection barrier between the new and the old owners, and made the new protocol meet a variety of security, such as non-traceability, and so on. A complete GNY logic security framework was established to prove the rationality and completeness of the protocol. Through the security analysis, it is proved that the improved protocol satisfies the security. The performance analysis shows that the improved protocol is applicable to the low cost of passive tags.更多还原
