【摘要】：针对射频识别(RFID)系统自身在认证和通信过程中存在的安全隐患问题,提出了一种低成本、高效、安全的RFID节点间身份认证与数据加密方案。该方案采用改进的椭圆曲线Diffie-Hellman(ECDH)算法与高级加密标准(AES)相结合的方式实现密钥分发、身份认证、通信加密功能,同时采用动态密钥算法增强了通信过程中的安全性。此外,该方案在不破坏安全强度的情况下缩减了运算规模,减少了系统资源开销。验证表明,该方案资源开销低,能够抵抗重放、假冒、中间人、拒绝服务等攻击,在对安全性能及低成本有一定要求的物联网领域具有一定的实用意义。
[Abstract]:A low cost and high efficiency radio frequency identification (RFID) system is proposed to solve the security problems in the process of authentication and communication. Secure authentication and data encryption scheme between RFID nodes. The improved Elliptic Curve Diffie-Hellman ECDH algorithm and the Advanced encryption Standard (AES) are used in this scheme. Key distribution is realized in a combined way. Identity authentication, communication encryption, dynamic key algorithm is used to enhance the security in the communication process. In addition, the scheme reduces the operation scale without breaking the security intensity. The system resource overhead is reduced. The verification shows that the scheme has low resource overhead and can resist replay, counterfeiting, middleman, denial of service and so on. It has certain practical significance in the field of Internet of things which has certain requirements for security performance and low cost.
