摘 要: 提出了一个基于可控隐形传态的量子代理多重签名方案。选择四粒子团簇态作为量子信道,利用可控量子隐形传态的物理特性来实现代理、签名及验证,方案还采用了量子密钥分配和一次一密算法。不同于基于计算复杂性的经典代理多重签名方案,本方案的安全性不受攻击者计算资源的影响,即具有无条件安全性。 A quantum proxy multi-signature scheme is presented based on controlled teleportation. We choose four-particle-cluster state as the quantum channel, use the physical characteristics of controlled quantum teleportation to implement delegation, signature and verification, and adopt quantum key distribution and one-time pad in our scheme. Different from the classical proxy multi-signature schemes based on computing complexity, its security is not influenced by the computational resource of attackers, that is, it has unconditional security.
