摘要:

基于量子纠缠交换的原理,提出了一种基于量子纠缠的盲签名方案。制备后的 EPR 纠缠粒子通过EPR纠缠交换,变化为全新的纠缠态。对新量子态的测量可以作为签名者和测量者的签名、测量依据,实现了量子通信、盲签及验证。不同于基于数学求解困难性的经典盲签名,本方案保证了消息对签名者的匿名性和方案的无条件安全性。

Abstract:

Based on the principle of quantum entanglement swapping, a blind signature scheme based on quantum entanglement was proposed.Through being entangled and exchanged, particles prepared before could transform into entangled state. The measurements of new entangled particles complete signature and verification and realize the quantum communication, blind signature and verification. Different from the classical blind signatures which based on the mathematics difficulty, the scheme could guarantee not only the anonymity but also the unconditionally security.

Key words: quantum information, quantum signature, blind signature, entangled quantum
