Quantum Key Distribution: A Safer Alternate To Asymmetric Key Exchange Policies

Quantum Key Distribution in the Classical Authenticated Key Exchange Framework

Key establishment is a crucial primitive for building secure channels in a multi-party setting. Without quantum mechanics, key establishment can only be done under the assumption that some computational problem is hard. Since digital communication can be easily eavesdropped and recorded, it is important to consider the secrecy of information anticipating future algorithmic and computational dis...

Asymmetric Key Distribution

Currently, in Threshold Public Key Systems key shares are generated uniformly and distributed in the same manner to every participant. We propose a new scheme, Asymmetric Key Distribution (AKD), in which one share server is provided with a larger, unequal chunk of the original secret key. Asymmetric Key Distribution is a unique scheme for generating and distributing unequal shares via a Trusted...

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...
