A Probabilistic Quantum Key Transfer Protocol

Abhishek Parakh

Abstract: We propose a protocol to transfer a one-time-pad (in a probabilistic manner) from Alice to Bob, over a public channel. The proposed protocol is unique because Bob merely acts as the receiver of the pad (secret key), i.e. Bob does not need to send any message back to Alice unless he detects eavesdropping. Such a secure transfer of one-time-pad, over public channel, is not possible in classical cryptography and in quantum cryptography all previous protocols require Bob to send almost as many messages back to Alice as she does to Bob, to establish a key.
