摘要
提出了一种新的基于混沌的量子身份认证方案,该方案将混沌系统对初值条件和参数的极度敏感性及混沌序列的良好伪随机性与量子密码的绝对安全性结合在一起,能够有效地抵抗多次身份认证中由于有限精度导致的混沌特性退化而造成对混沌系统初值和参数的攻击。在方案的实现过程中,利用量子隐形传态原理,解决了多次身份认证中出现的混沌迭代异步问题,实现了每一次身份认证中双方的同步,从而实现了"一次一密"的量子身份认证。整个身份认证过程实现简单,具有动态性和可证明的安全性。
A new quantum identity authentication scheme is proposed based on chaos. The scheme combines the extreme sensitivity to initial conditions and parameters of chaotic system and good pseudo-randomness of chaotic sequence with absolute security of quantum cryptography. It can resist the attack on initial values and parameters of chaotic system which is based on finite precision. In order to solve the chaotic iterative asynchronous problem, principle of quantum teleportation was used in the program implementation process. The scheme realizes the ＂ one-time pad ＂ authentication. The whole authentication process is simple in implementation with mobility and provable security.
