Abstract:In practical applications, the ownership problem of multiple tags is often encountered in one call. Most of the existing ownership transfer protocols are applicable only to the transfer of single label ownership. In order to solve the problem, a multi label transfer protocol is designed. The proposed protocol can reduce the number of communication entities in the system without relying on trusted third parties. The protocol encrypts the transmission message based on the Chinese Remainder Theorem and word Cro operation to ensure the safety and reliability of communication messages. In the process of one call, the protocol can transfer the ownership of multiple labels simultaneously. Based on the logic formalization of BAN, the mathematical proof process is given, and the security and performance of the protocol are analyzed. It shows that the protocol has the security and low computation needed for the transfer of ownership.
