摘要: 物联网中RFID技术的应用非常广泛,但是RFID系统的安全性却存在着很大隐患。在RFID系统中标签与读写器间的通信信道是最易受到攻击,传输数据的完整性与保密性得不到保障,因而需要加强RFID系统通信的安全机制。考虑到RFID系统的硬件条件与成本限制,需要建立一个适合RFID系统的安全认证协议,来解决在RFID系统中信息传输所遇到的安全问题。PRESENT算法是轻量级的分组加密算法,将PRESENT结合到RFID系统的安全认证协议中,形成了新的RFID安全认证协议PRSA(PRESENT based RFID security authentication)。此协议可以增强RFID系统的安全性而又不会占用过多的硬件资源,从而能够适用于低成本的RFID系统的通信安全。

Abstract: Although RFID technologies in the Internet of Things are widely applied. The security of the RFID system has very big challenges. The communication channel between the tag and the reader of the RFID system was most vulnerable, so the integrity and the confidentiality of data transmission could not be guaranteed. Therefore, A protocol to strengthen the security of RFID system communication need to be consider. Taking into account the RFID system hardware conditions and cost constraints, to establish a suitable RFID system security authentication protocol so as to solve the problems encountered in the information transmission. The PRESENT algorithm was a lightweight block cipher, so the PRESENT algorithm was combined with the security authentication protocol in RFID system, and form a new RFID security authentication protocol PRSA (Present based RFID security authentication). PRSA protocol can not only enhance the RFID system security, but also occupy very few hardware resources. Thus PRSA protocol can adapt to the security of communication in the low-cost RFID system.
