量子安全的经典知识

Classical Knowledge for Quantum Security

Ellie D'Hondt, Mehrnoosh Sadrzadeh

摘要:

本文提出了一种分析量子密码协议安全性的判定方法,将经典的知识代数重写系统与量子分布式计算的操作语义相结合。作为一个测试案例,我们使用我们的程序的原因最近开发的量子秘密共享协议,使用图形状态的安全属性。我们根据经典和量子信道的安全假设分析了三种不同的场景,并发现了对手存在时的攻击路径。导致这种和类似类型攻击的认识论分析纯粹是基于我们的经典知识观。

英文摘要:

We propose a decision procedure for analysing security of quantum cryptographic protocols, combining a classical algebraic rewrite system for knowledge with an operational semantics for quantum distributed computing. As a test case, we use our procedure to reason about security properties of a recently developed quantum secret sharing protocol that uses graph states. We analyze three different scenarios based on the safety assumptions of the classical and quantum channels and discover the path of an attack in the presence of an adversary. The epistemic analysis that leads to this and similar types of attacks is purely based on our classical notion of knowledge.
