Abstrakt

The appealing feature of quantum key distribution (QKD), from a

cryptographic viewpoint, is the ability to prove the

information-theoretic security (ITS) of the established keys. As a key

establishment primitive, QKD however does not provide a standalone

security service in its own: the secret keys established by QKD are in

general then used by a subsequent cryptographic applications for which

the requirements, the context of use and the security properties can

vary. It is therefore important, in the perspective of integrating QKD

in security infrastructures, to analyze how QKD can be combined with

other cryptographic primitives. The purpose of this survey article,

which is mostly centered on European research results, is to contribute

to such an analysis. We first review and compare the properties of the

existing key establishment techniques, QKD being one of them. We then

study more specifically two generic scenarios related to the practical

use of QKD in cryptographic infrastructures: 1) using QKD as a key

renewal technique for a symmetric cipher over a point-to-point link; 2)

using QKD in a network containing many users with the objective of

offering any-to-any key establishment service. We discuss the

constraints as well as the potential interest of using QKD in these

contexts. We finally give an overview of challenges relative to the

development of QKD technology that also constitute potential avenues for

cryptographic research.
