【摘要】 低成本无线射频识别系统的应用受制于其成本及安全问题。低成本无线射频识别标签只具备极有限的计算能力,传统的加密方法如分组加密、哈希函数已超出了低成本RFID标签的运算能力。因此,提出了只使用简单的位运算和模运算等的超轻量认证协议。综述了近年来在低成本RFID超轻量认证协议方面的研究成果及发展动态。更多还原

【Abstract】 Low-cost Radio Frequency Identification(RFID) systems are nowadays mainly limited by security concerns and by their cost.Low-cost RFID tags are devices with very limited computational capability,traditional cryptography such as block ciphers or hash functions are well beyond the computational capabilities of low-cost RFID tags.For this reason,ultra-lightweight authentication protocols,involve only simple bitwise and modular arithmetic operations,are proposed.Recent results and trends on Low-cost RFID ultra-lightweight authentication protocols are surveyed.更多还原
