Abstract content <br> &nbsp; (Max 300 words)

Quantum Key Distribution (QKD) is an encryption scheme which uses two concepts of quantum mechanics, namely No-cloning Theorem and Uncertainty Principle, to allow a secure exchange of a cryptographic key between two communicating parties; Alice (sender) and Bob (receiver) in such a way that the presence of an eavesdropper (Eve) could be detected.

In this paper, we report our work on the implementation of the B92 QKD protocol on id3100 Clavis2 `plug-and-play' cryptosystem. Traditionally, this cryptosystem only supports two four-state QKD protocols, namely BB84 and SARG04 protocols. However, we show in this work that it is possible to implement a two-state protocol (B92) in such a system, by changing the number of encoded state. Additionally, we provide a security analysis of our approach, in order to ascertain its feasibility.
