A security enhancement approach in quantum cryptography

Security in quantum cryptography algorithms is one of the main research directions in the field of quantum cryptography. This paper proposes a new algorithm which provides two phase security to the quantum cryptography System. In the proposed Algorithm the presence of the eavesdropper will not affect the security of the system as the secret key bits are modified at both Sender and Receiver end based on the concept of prime factor. Hence provide a more effective method which will make quantum cryptography more efficient and robust.
