带有TTP权重的多所有者标签所有权转换协议研究

RFID Tag Ownership Transfer Protocol of Multi-owner with Different Weights and TTP

针对多所有者RFID标签所有权转换问题,提出了一种带有TTP权重的多所有者标签所有权转换协议。所有权的变化不仅是由标签的所有者发生变化引起,同时不同的所有者所占有权重发生变化也会导致所有权的变化。由于可信第三方参与所有权的转换,使得原所有者可完全地将对标签的所有权转交给新所有者,该协议具备原所有者无关性。使用GNY逻辑对该协议进行了安全性分析,并进行了仿真实验。结果表明:该协议能抵抗转换过程中的多种攻击,同时标签耗时较低。

With regard to the multi-owner RFID tags ownership transfer,a multi-owner RFID tags ownership transfer protocol based on TTP weights was put forward.Not only will the change in the owner of the tag result in the change in ownership,but the change in the weights of different owners will result in the change in ownership.Because there is a trusted third party involved in the conversion of ownership,the original owner completely transfers the tag's ownership to the new owner,that is to say,the protocol original owner shall be irrelevant.Security analysis is conducted with GNY logic,and simulation experiments are carried out on the protocol.The result shows that it can resist all kinds of attacks in the process of conversion;meanwhile,the tags take less time.
