轻型的RFID安全认证协议LAP

RFID标签存在着处理能力弱、存储空间小和电源供给有限等局限性，传统的公钥算法或散列函数等复杂运算不能满足实际应用的需求。针对现有轻量级RFID认证协议的不足，设计了基于广义逆矩阵的RFID安全认证协议LAP。该协议采用了硬件复杂度较低的CRC校验及计算量较小的矩阵运算。通过安全隐私和性能分析，LAP协议适用于低成本、存储与计算受限的RFID标签。

Lightweight authentication protocol for RFID

Radio frequency identification (RFID) is a technique using radio frequency to object identification and access to relevant data in the open system enviroment with the limits of process, storage, power and so on. The traditional tag authentication protocols taking complicated algorithms into account can't meet the demand. In view of the existing secu-rity and privacy problems of RFID , a lightweight authentication protocol for RFID named LAP was proposed. LAP is based on the generalized inverse matrix and only uses CRC checksum, some matrix and simple logic operations to satisfy the principles of balancing security, privacy and cost. The comparisons of security, privacy and performance with other authentication protocols show that LAP is feasible for RFID tags with requirements of low cost and resource-constrained.
