摘要
针对无线射频识别(RFID)中阅读器与标签之间的无线通信安全问题,基于椭圆曲线密码算法,提出一种RFID双向认证协议。描述新协议过程,给出安全性分析,该方案不仅提供了RFID系统中阅读器与标签的双向认证,而且满足防范重放攻击、窃听攻击、中间人攻击等安全要求,并利用BAN逻辑证明新协议的安全性。安全性分析结果表明,该协议基于椭圆曲线离散对数困难问题,与现有公钥密码体制相比,安全强度高、密钥长度短、存储量小,且具有较高的通信效率。
Aiming at wireless communication security problem of Radio Frequency Identification（RFID） the based on Elliptic Curve Cryptography （ECC） algorithm,this paper proposes a RFID mutual authentication protocol.It describes in detail the process of the new protocol and gives the safety analysis,the proposed protocol not only provides two-way authentication RFID reader and tag system,and meets the protecting against replay attacks,eavesdropping attacks,middle attacks and other security requirements.The security new protocol is proved by BAN logic.Security analysis result shows that the security of ECC is based on the difficulty of Elliptic Curve Discrete Logarithm Problem （ECDLP）,comparing with other asymmetric cryptography,ECC has stronger security,shorter key length,smaller storage capacity and it has high communication efficiency.
