A Theoretical Model of Multi-user QKD Network as the Extension of E91 Protocol

Vikas Jha, Pankaj Srivastava

Abstract


A theoretical model is represented by us towards the scope of developing a Quantum key distribution network. There is always a requirement of secured and confidential information processing so that the authentic and legitimate information one can get each time. Hence the quest for obtaining a perfect cypher continues. Considering the recent development in cryptography it was found that quantum mechanics exhibiting more solidarity when applied to cryptography and that generated a new dimension of secured information processing known as Quantum Cryptography. We propose a theoretical model of a network that will be used for quantum key distribution among n X n users of the network as the extension of two-party E91 protocol for multiple users simultaneously. Applying the concept of parallel Hadamard transform with optical fiber channels gives us the platform of WDM multiplexing and de-multiplexing through the network.
