摘要:

基于目前资源消耗最少的RFID 公钥认证方案cryptoGPS 协议,提出了一种低成本双向认证协议,采用有效的密钥管理方法、改进的快速Rabin 加密算法、低汉明重量(LHW)模值以及轻量级流密码算法Grain V1,并设计使用新型低资源乘法器完成标签的大数模乘,在节省资源的同时克服了cryptoGPS 密钥管理不灵活和认证单向性的缺点。安全性分析和基于Design Complier平台Smic 0.25 μm工艺的仿真结果表明,该方案有足够的安全性且标签只需4 530个门即可完成双向认证,适用于资源受限的RFID系统。

Abstract:

Based on the PKC-based RFID authentication protocol cryptoGPS which costs the least resource currently,a low-cost mutual authentication protocol which has a flexible key-management and can realize a mutual authentication was proposed.It adopted a new key-management scheme,an optimized fast Rabin encryption algorithm,low Hamming weight modulus and a lightweight stream cipher algorithm Grain V1,moreover,a new low-cost multiplier was designed to achieve the modulus multiplication on large numbers.The security analysis and simulation experiments carried out on Design Complier with Smic 0.25 μm technique show that this scheme is secure enough and in which the tag just needs 4 530 gates,it is suitable for RFID system.

Key words: RFID, public key cryptography, cryptoGPS, mutual authentication protocol
