【摘要】：RFID(无线射频识别)技术以无线通信的方式广泛运用于生活生产的各个领域,如门禁设备、支付设备等,但阅读器和标签之间无线开放的通信环境使得RFID设备面临更多的恶意攻击和安全威胁。低成本标签只具有非常有限的计算能力和存储空间,一般的分组密码和hash函数等都不能用于低成本标签中。为了解决低成本标签的安全性问题,采用比特位运算密码原语,提出一种新的超轻量级RFID认证协议——SIUAP。SIUAP协议在SIMON类算法的超轻量级轮函数F(x)和非线性函数MIXBITS运算的基础上,使用3种简单的比特位运算:比特AND运算、异或运算和循环移位运算,大大降低了计算复杂度。通过GNY逻辑对协议进行形式化的分析,证明了SIUAP协议能够实现阅读器和标签双向合法身份的认证,同时对SIUAP进行安全性分析。与现有的超轻量级认证协议相比,SIUAP协议具有较小的计算开销,能够满足RFID系统低成本、高安全性的需求。
[Abstract]:RFID (Radio Frequency Identification) technology is widely used in various fields of life and production by means of wireless communication, such as access control equipment, payment equipment and so on. However, the wireless open communication environment between readers and tags makes RFID devices face more malicious attacks and security threats. Low-cost tags only have very limited computing power and storage space, and general block ciphers and hash functions can not be used in low-cost tags. In order to solve the security problem of low cost tags, the bit operation cipher primitive is adopted. In this paper, a new ultra-lightweight RFID authentication protocol, SIUAP.SIUAP protocol, is proposed. Based on the ultra-lightweight wheel function F (x) and nonlinear function MIXBITS operation of SIMON class algorithm, three simple bit operations are used: bit AND operation. XOR operation and cyclic shift operation greatly reduce the computational complexity. Through the formal analysis of the protocol by GNY logic, it is proved that the SIUAP protocol can realize the authentication of the two-way legal identity of reader and tag, and the security of SIUAP is analyzed at the same time. Compared with the existing ultra-lightweight authentication protocol, SIUAP protocol has less computing overhead and can meet the requirements of low cost and high security of RFID system.
