Quantum key Distribution with a Hand-Held Sender Unit

Quantum key distribution with authentication

The security of the previous quantum key distribution (QKD) protocols, which is guaranteed by the nature of physics law, is based on the legitimate users. However, impersonation of the legitimate communicators by eavesdroppers, in practice, will be inevitable. In fact, the previous QKD protocols is un secure without authentication in practical communication. In this paper, we proposed an improv...

Quantum key distribution with trusted quantum relay

A trusted quantum relay is introduced to enable quantum key distribution links to form the basic legs in a quantum key distribution network. The idea is based on the well-known intercept/resend eavesdropping. The same scheme can be used to make quantum key distribution between several parties. No entanglement is required.

Quantum Key Distribution

Quantum Authenticated Key Distribution

Quantum key distribution algorithms use a quantum communication channel with quantum information and a classical communication channel for binary information. The classical channel, in all algorithms to date, was required to be authenticated. Moreover, Lomonaco [8] claimed that authentication is not possible using only quantum means. This paper reverses this claim. We design an algorithm for qu...

Quantum Key Distribution - QKD

This paper provides an overview of quantum key distribution targeted towards the computer science community. A brief description of the relevant principles from quantum mechanics is provided before surveying the most prominent quantum key distribution protocols present in the literature. In particular this paper describes the BB84 protocol and its many variants as well as Eckert's approach thro...
