摘要
由于物联网感知前端射频识别系统的工作环境是完全开放的,因此应答器和读写器之间的通信是在完全没有保护的情况下进行的。这就使得物联网用户的信息安全和个人隐私面对着各种各样的威胁。使用高级加密算法的应答器和读写器双向认证协议由于硬件实现成本高而限制了它在物联网中的应用范围。该文通过在应答器和读写器的双向认证过程中引入数据隐藏算法来确保信息传输过程中的安全性,并对其应用的可行性进行分析。
Due to the fully open working environment of Radio frequency identification system ,the communication between tag and reader is exposed to all kinds of threats. Further, IOT user’s information and their personal privacy are dangerous. Because of the high cost of hardware implementation, using advanced encryption algorithm to carry out two-way authentication among readers and tags limits its application in the IOT. In this paper, we introduce data hiding algorithm to ensure the security of infor-mation transmission among readers and tags through the whole tow-way authentication process. Finally, the feasibility of the scheme was analyzed.
