摘要: 在物联网环境下,嵌有无线射频识别标签的商品在交易过程中标签隐私信息可能会遭到泄露。针对该问题,基于可信第三方对称密钥更新管理策略,采用字合成运算方法对所要传输的信息进行加密,利用不同的随机数保持各消息的新鲜性,提出一种超轻量级群组射频识别标签所有权转移协议。仿真结果表明,与小组转移协议、无线射频识别和安全小组转移协议相比,该协议不仅满足所有权转移协议的安全性需求,而且因采用位运算进行加密,使得成本减少,有效降低了计算量,节约了计算时间。

Abstract: In the Internet of Things(IOT) environment, the label privacy information of the goods embedded with Radio Frequency Identification(RFID) tag may be leaked in the process of trading. Aiming at this problem,an ultra-lightweight group RFID tag ownership transfer protocol is proposed based on the Trusted Third Party(TTP) symmetric key update management strategy,in which the word synthesis method is used to encrypt the information to be transmitted and the freshness of each message is maintained by different random numbers.Simulation results show that compared with the group transfer protocol,radio frequency identification and security group transfer protocol,the proposed protocol not only satisfies the security requirements of ownership transfer protocols,but also uses the bit operation to encrypt,which reduces the cost and computation amount and saves the calculation time.

Key words: Internet of Things(IOT), group, ownership transfer, Trusted Third Party(TTP), replay attack
