非交互量子统计与完美零知识

Non-Interactive Quantum Statistical and Perfect Zero-Knowledge

Hirotada Kobayashi

摘要:

本文介绍了非交互式完美和统计零知识证明系统的量子模拟。与经典的情形类似,我们证明了对于非交互量子完美和统计零知识的非平凡协议,共享随机性或纠缠是必要的。它还表明,共享EPR对先验,类语言具有单侧有界错误的非交互式量子完美零知识证明系统有一个自然的完全问题。这种证明系统的非平凡性是基于本文证明的事实,即图的非自同构问题,这是不知道在BQP,可以减少到我们的完全问题。我们的结果可能是第一个非平凡的量子零知识证明安全,即使对不诚实的量子验证者,因为我们的协议是非交互式的,因此零知识属性不依赖于协议中的验证者是否诚实。我们的完整问题的一个限制版本导出了BQP的一个自然完整问题。

英文摘要:

This paper introduces quantum analogues of non-interactive perfect and statistical zero-knowledge proof systems. Similar to the classical cases, it is shown that sharing randomness or entanglement is necessary for non-trivial protocols of non-interactive quantum perfect and statistical zero-knowledge. It is also shown that, with sharing EPR pairs a priori, the class of languages having one-sided bounded error non-interactive quantum perfect zero-knowledge proof systems has a natural complete problem. Non-triviality of such a proof system is based on the fact proved in this paper that the Graph Non-Automorphism problem, which is not known in BQP, can be reduced to our complete problem. Our results may be the first non-trivial quantum zero-knowledge proofs secure even against dishonest quantum verifiers, since our protocols are non-interactive, and thus the zero-knowledge property does not depend on whether the verifier in the protocol is honest or not. A restricted version of our complete problem derives a natural complete problem for BQP.
