Abstract

Information-theoretical security secret key agreement protocol has become hot in recent years.QKD could also be included into it.If people thoroughly understand it,they can know more about QKD from a higher level.It also reveals the security and limitations of the way using classical key distribution.This paper summarizes the all points in the information-theoretical security secret key agreement protocol(ITSSKP).

Overview of Quantum Key Distribution Network Key-Delivery Specifications

Miralem Mehić, Stefan Raß, Emir Dervisevic +3 more

Quantum Key Distribution (QKD), a secret key agreement primitive, makes possible long-awaited real-world Information-Theoretical Security (ITS). In the last twenty years, the development of QKD-based networks that deliver ITS keys to distant parties has been a focus of the academic and industry sectors. Several key-delivery specifications have been developed for the practical delivery of keys to end applications. In this paper, we discuss key-delivery specifications with a focus on security and authentication.

The security of practical quantum key distribution

Valerio Scarani, Helle Bechmann-Pasquinucci, Nicolas J. Cerf +3 more

Quantum key distribution (QKD) is the first quantum information task to reach the level of mature technology, already fit for commercialization. It aims at the creation of a secret key between authorized partners connected by a quantum channel and a classical authenticated channel. The security of the key can in principle be guaranteed without putting any restriction on an eavesdropper's power. This article provides a concise up-to-date review of QKD, biased toward the practical side. Essential theoretical tools that have been developed to assess the security of the main experimental platforms are presented (discrete-variable, continuous-variable, and distributed-phase-reference protocols).

Semi-Quantum Key Distribution with Limited Measurement Capabilities

Walter O. Krawec, Eric P. Geiss

A semi-quantum key distribution (SQKD) protocol allows a quantum user and a limited "classical" user to establish a shared secret key secure against an all-powerful adversary. In this work, we present a new SQKD protocol where the quantum user is also limited in her measurement capabilities. We describe the protocol, perform an information theoretic analysis of its security, and show its noise tolerance is as high as "fully quantum" QKD protocols.

From Classical to Semi-Quantum Secure Communication

Allison Gagliano, Walter O. Krawec, Hasan Iqbal

In this work we introduce a novel QKD protocol capable of smoothly transitioning, via a user-tuneable parameter, from classical to semi-quantum in order to help understand the effect of quantum communication resources on secure key distribution. We perform an information theoretic security analysis of this protocol to determine what level of "quantumness" is sufficient to achieve security, and we discover some rather interesting properties of this protocol along the way.

Some Aspects of Quantum Cryptography and Network Security

Jaydip Sen, Chowdhury, Piyali Roy, Indranil Sengupta

Quantum mechanics is the current best description of the world as we know it. Experiments have shown that quantum predictions are accurate up ten places of decimal. In quantum cryptography much work has been devoted to the study of Quantum Key Distribution (QKD). The purpose of QKD is to securely distribute secret keys between the users in a network. As a result, several quantum cryptographic protocols have been implemented and tested after the advent of quantum computing. In this paper, we have given a brief overview of QKD, and some practical networks that integrate QKD in the current Internet security architecture. We have also discussed some aspects of quantum network security with particular attention to Byzantine Agreement Protocol.
