摘　　要：基于RSA衍生的判定性DependentRSA问题的困难性假设,提出一个安全高效的身份鉴别方案。在标准模型下,可证明该身份鉴别协议在主动并行攻击下能抵抗冒充攻击和中间人攻击。由于交互简单自然、低存储量、低计算量和好的安全性能,该身份鉴别协议更适合用于广泛应用的智能卡。Based on the hardness assumption of the decisional relevant RSA （ DDRSA for short, which derived from RSA problem）, presented a secure and efficient identification protocol. Proved the proposed identification protocol secure against impersonation and man-in-the-middle attack under both active and concurrent attacks in standard model. Due to its simplicity and naturalness, low-memory, low-computation loads, and better security, the proposed scheme is well suitable for using in smart cards.
