摘　　要：射频识别技术(Radio Frequency Identification,RFID)作为物联网中标识物品的关键技术,其因低成本、易携带等优势而得到了广泛的应用。基于云存储的RFID技术相较于传统RFID技术更具有应用市场,但其安全隐私问题也更为严重。另外,现有的很多群组标签认证协议不仅不符合轻量级要求,还具有密钥失同步的问题。文中提出一种基于云的轻量级RFID群组标签认证协议。该协议基于Hash函数而设计,它不仅解决了上述安全隐患,还能在群组认证过程中筛除无效标签和假冒标签。最后,利用BAN逻辑对该协议进行了分析。安全目标分析表明,该协议可以抗多重DOS攻击以及其他基本攻击,并满足前向安全性。As a key technology for indentifying objects in the Internet of Things(IoT),radio frequency identification(RFID)technology has been widely used because of its advantages,such as low cost and easy to carry.The RFID system based on cloud storage technology has a more widely application market comparing with the traditional RFID system,but its security and privacy issues are more serious.At the same time,many existing group authentication protocols don’t meet the lightweight requirements,and have the lost synchronization problem in key updating process.This paper proposed a cloud-based lightweight RFID tag group authentication protocol.This protocol is based on the Hash function,which not only resolves these issues above,but also filters out the invalid and fake labels.Finally,this paper conducted the formal analysis of the proposed protocol by using BAN logic.The security target analysis shows that the proposed protocol can resist the multi-DOS attack and other common attacks,and possesses the forward security.
