A Novel Quantum Cryptography Protocol

Quantum key distribution is a sub topic under quantum cryptography where two parties distribute a shared random bit string known only to them and which can be used as a key to encrypt and decrypt messages. This paper proposes a novel method of QKD to distribute the secret key. The basic concept of QKD remains the same but the process by which the key is exchanged between the two parties is different and is much more secure than the existing QKD protocols. The proposed method exploits the concept of hamming weight.
