基于开环状态的标签所有权转移改进协议

An Improved Protocol for Tag Ownership Transfer Based on Open-loop State

电子标签生命周期中,电子标签的拥有者常发生变更,为确保变更前后拥有者存放在电子标签内部隐私信息的安全性,设计了一种所有权转移协议。协议适用于开环状态下的RFID系统中;为保障发送消息的安全性,采用二次剩余定理加密,同时为尽可能降低通信整体计算量,结合创新型的置换交叉合成运算对部分信息加密。协议与近年其他此类型协议做安全和性能对比,协议具备拥有者所需求的安全标准,以及具备现有低成本电子标签计算的要求特征。

During the life-cycle of the electronic tag,the owner of the electronic tag often changes.In order to ensure the security of the owner’s private information stored in the electronic tag before and after the change,a protocol for ownership transfer is designed.The protocol is adequate for the RFID system in the open-loop state.For the security of sending message,the quadratic residual theorem is used for encryption.Meanwhile,in order to reduce the total amount of communication computation as much as possible,the innovative permutation cross synthesis operation is used to encrypt part of the information.Compared with other protocols of the same kind on security and performance in recent years,the protocol has the security standard required by the owner and the characteristics of the existing low-cost computing for electronic tag.
