基于一次一密的量子身份识别方案

Quantum identification based on one-time pad

给出一个基于Holevo定理的量子单向函数,并根据它构造了一个基于对称密码体制的量子身份识别方案.该方案通过一次性的随机数隐藏了双方共享的密钥,且验证算法不依赖于所使用的随机数,从而保护了密钥,使该方案的安全性不局限于敌手的计算能力.

We propose a quantum identification scheme. The scheme uses one-time random strings to hide the key shared by both sides, and the verification algorithm is independent of the random strings. So it protects the key. The scheme is secure even if the adversary has unlimited resource of computation.
