New directions in quantum cryptography

Akash Shrivastava, Manvendra Pratap Singh

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.

Quantum cryptography has attracted a lot of attention in recent years, due to its particular characteristic of perfect security in information transmission.The most successful and important application-quantum key distribution,which has been applied firstly in quantum cryptography,was introduced by taking BB84 protocol as an example.The current state of research and future directions in this new field of science was briefly presented.

-The main goal of this paper is combining the curve security methods with quantum cryptography concepts in order to increase the capability of quantum cryptography methods that used for key distribution and increase the randomness for quantum cryptography protocols. This paper produced a new approach depend on the generate curve and descript this curve by using quantum cryptography concepts, the curve description will be sent to the other party to agree about the key depending on the suggested protocol that produced in this paper. Curve security involves the process of protecting the shape of the curve from reproduced and as a result, protecting the whole document from being regenerated by any counterfeiting person. On the other hand, the strength of quantum cryptography is based on the quantum behavior of the photons when it is measured in a different basis; it is resulted in a random value and information destruction. The combination of the two cryptography direction guaranteed that the resulted key have the required randomness. The key is tested using the different randomness tests, which prove the high randomness of the keys that are resulted with this approach.
