QKD量子信道认证

QKD Quantum Channel Authentication

J. T. Kosloski

摘要:

提出了几种简单而安全的协议,通过耦合光子发送者的共享秘密的知识和QBER Bob观察到的各种QKD方案的量子信道的认证。它表明,爱丽丝可以加密的QKD协议所需的信息的某些部分,使用的序列,其安全性是基于计算的复杂性,而不会损害所有的序列的熵。然后表明,在对量子和经典信道进行中间人攻击后,序列中仍然有足够的熵,Bob可以通过监视QBER来检测Eve的存在。最后,它表明,所提出的原则可以实现认证的量子信道与任何类型的QKD方案,他们也可以用于爱丽丝认证鲍勃。

英文摘要:

Several simple yet secure protocols to authenticate the quantum channel of various QKD schemes, by coupling the photon sender's knowledge of a shared secret and the QBER Bob observes, are presented. It is shown that Alice can encrypt certain portions of the information needed for the QKD protocols, using a sequence whose security is based on computational-complexity, without compromising all of the sequence's entropy. It is then shown that after a Man-in-the-Middle attack on the quantum and classical channels, there is still enough entropy left in the sequence for Bob to detect the presence of Eve by monitoring the QBER. Finally, it is shown that the principles presented can be implemented to authenticate the quantum channel associated with any type of QKD scheme, and they can also be used for Alice to authenticate Bob.
