Overview of Quantum Key Distribution Network Key-Delivery Specifications

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.
