摘　　要：物联网环境下无线射频(RFID)标签具有明显的群组特性,对单标签所有权转移方案扩展设计出高安全、低成本的群组标签所有权转移方案是一个新的挑战。为此,设计一种基于组签名的RFID群组标签所有权转移方案,以轻量级低运算量为原则,利用自组合交叉位运算,生成完整组签名标识,授权认证通过后实现新旧所有权的安全转移。在提出通用可组合安全模型下,定义群组标签转移理想函数,证明得到所需安全目标,并对比相关方案,其结果表明,该方案满足标签低成本标准,具有更高的认证、转移效率。In the environment of Internet of things,radio frequency identification(RFID)tags have obvious group characteristics.It is a new challenge to expand the single tag ownership transfer scheme and design a high security and low cost group tag ownership transfer scheme.To meet the challenge,a group signature based RFID group tag ownership transfer scheme was designed.Based on the principle of lightweight and low computational complexity,the self-assembly crossover bit operation was used to generate a complete group signature identification.After the authentication was passed,the old and new ownership were transferred safely.Under the UC(universally composable)security model,a group tag transfer ideal function was defined,and the desired security objectives were proved.Compared with the related schemes,it shows that the proposed scheme meets the low cost standard of tags,and has higher authentication and transfer efficiency.
