摘　　要：在分析现有无线射频识别(RFID)通信协议在应用中存在的安全及隐私问题的基础上,结合公钥加密算法和对称密钥加密算法,提出了在RFID标签芯片计算资源受限的情况下解决这些问题的一个轻量安全通信协议,并给出了基于逻辑分析的形式化证明.该协议能够解决RFID系统中存在的信息泄露、重放攻击、位置追踪、假冒攻击、去同步化、前向安全等安全问题,具有很好的安全性和私密性,且具有较好的实现效率和实现成本,适合实际RFID系统的使用.Based on the analysis of the features and issues pertinent to the current radio frequency identification(RFID) communication protocols,a lightweight security communication protocol(LSCP) was proposed combining public key encryption and symmetric cryptosystem.The formal proof of correctness of new protocol was given based on logic.The proposed protocol can be used to prevent many security problems including information leakage,replay attack,location tracing,spoofing attack and forward security etc.It has good security and privacy.Moreover,the performance and cost of the protocol had also been analyzed,results show that the protocol is suitable for practical use in RFID system.
