零知识系统证明转移的量子协议

Quantum protocols for transference of proof of zero-knowledge systems

Jose Claudio do Nascimento, Rubens Viana Ramos

摘要:

零知识证明系统是一个重要的协议,可以作为构造其他更复杂密码协议的基本模块。零知识系统的一个内在特征是假设验证者不可能向第三方表明他与证明者进行了交互。然而,已经表明,使用量子关联可以成功地攻击不可能转移证明。在这项工作中,我们提出了两个新的协议的证明转移,是第一个基于隐形传态和第二个不使用纠缠态。

英文摘要:

Zero-knowledge proof system is an important protocol that can be used as a basic block for construction of other more complex cryptographic protocols. An intrinsic characteristic of a zero-knowledge systems is the assumption that is impossible for the verifier to show to a third part that he has interacted with the prover. However, it has been shown that using quantum correlations the impossibility of transferring proofs can be successfully attacked. In this work we show two new protocols for proof transference, being the first one based on teleportation and the second one without using entangled states.
