Abstract:

The ownership of the tag often changes during the use of the tag. In order to ensure the security of the privacy information of related communication entities, a lower cost tag ownership transfer protocol is proposed. In order to ensure the security of the private information of the communicating entities, the proposed protocol uses the cycle function and the quadratic residual theorem to encrypt the information. The private shared key synchronization update mechanism between the tag’s new owner and the tag is used to ensure the forward and backward security of the transfer protocol. A comparative analysis of the security between the proposed protocol and other such related protocols, as well as performance comparison analysis, highlights the high security and low cost of the proposed protocol.
