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.

摘要：

标签在使用过程中，标签的所有权归属者经常会发生变化。为了确保相关通信实体隐私信息的安全性，提出一种成本较低的标签所有权转移协议。为保障通信实体各方隐私信息的安全，所提出的协议采用循转函数及二次剩余定理对信息进行加密；采用标签新所有者与标签之间共享密钥二次同步更新机制，来保证所有权转移协议的前后向安全性。给出所提协议与其他此类相关协议之间的安全性比较分析，以及性能比较分析，突出所提协议的安全性高、成本低特性。
