基于量子纠缠和对称密码的混合认证协议

A Hybrid Authentication Protocol Using Quantum Entanglement and Symmetric Cryptography

D. R. Kuhn

摘要:

本文提出了一种混合密码协议,使用量子和经典的资源,在网络中的认证和授权。一个或多个可信服务器将纠缠光子流分发给寻求通信的各个资源。假设每个资源与可信服务器共享先前分发的密钥,并且资源可以使用经典信道和量子信道与服务器通信。资源之间不共享密钥,因此网络的密钥分配问题从O(n^2)减少到O(n)。该协议的优点是避免了经典协议中对时间戳的要求,保证了可信服务器不知道认证密钥,能够抵抗多光子分裂攻击,并且可以与BB84或其他量子密钥分发协议一起使用。

英文摘要:

This paper presents a hybrid cryptographic protocol, using quantum and classical resources, for authentication and authorization in a network. One or more trusted servers distribute streams of entangled photons to individual resources that seek to communicate. It is assumed that each resource shares a previously distributed secret key with the trusted server, and that resources can communicate with the server using both classical and quantum channels. Resources do not share secret keys with each other, so that the key distribution problem for the network is reduced from O(n^2) to O(n). Some advantages of the protocol are that it avoids the requirement for timestamps used in classical protocols, guarantees that the trusted server cannot know the authentication key, can provide resistance to multiple photon splitting attacks and can be used with BB84 or other quantum key distribution protocols.
