基于智能卡芯片指纹的身份认证方案设计

Design of User Authentication Scheme Based on Smart Card's Chip Signature

身份认证在网络安全中有非常着重要的作用。最近,Das等人提出了一种基于智能卡和动态ID的身份认证方案。在分析其方案漏洞的基础上,引入芯片指纹和随机数,提出了一种改进方案,能有效地抵抗伪装攻击、芯片复制攻击、拒绝服务攻击、重传攻击、口令猜测攻击,在对系统安全度要求较高的环境中有着良好的应用前景。

User authentication has very important applications in network security. Recently, Das et al. proposed a user authentication scheme based on smartcard and dynamic ID. We propose an improved scheme by introducing chip signature and random numbers after analyzing the loopholes of the original scheme. Our scheme can effectively withstand masquerade attack, chip-reproducing attack, DoS attack, replay attack and guessing attack.Our scheme has a promising prospect in environment where demands high system security.
