Aspects of Quantum Cryptography and Applications

Shravan Kumar Sehgal, Rashmi Gupta

the area of Quantum Cryptography is a new and upcoming field in terms of security of data. Unlike the normal Cryptography techniques this technique is faster and also can handle large amount of data as it works on qubits and on the principle of Heisenberg Uncertainty. Quantum cryptography deals with the security applications mainly used in Quantum Computers now a days. Furthermore, a security evaluation is given and any kind of attack that would present in any event a slip up speed of 46.875%. The paper represents various algorithm that are used in quantum cryptography along with its comparison with the existing classical cryptography algorithms. It also includes the shortcomings of the present algorithms and the future aspect of quantum cryptography.

In internet and network applications the most challenging aspects is the security. The importance and the value of exchanged data over internet is increasing due to growth in internet and network applications. Cryptography converts the information from normal form to unreadable form, in the computer security. The one encryption algorithm is identified and differentiated from another by two main characteristics that are speed and the efficiency and have the ability to secure the protected data against attacks. Fundamental laws of the quantum physics are applied by Quantum Cryptography to guarantee the secure communication between the legitimate users, namely Alice and Bob. Quantum mechanics is used by Quantum Key Distribution to guarantee the secure communication. This paper provides the comparative analysis on Classical and Quantum Cryptography using various cryptographic algorithms to identify the best algorithm in classical or quantum cryptography.

Data that is transient over an unsecured wireless network is always susceptible to being intercepted by anyone within the range of the wireless signal.Hence providing secure communication to keep the user's information and devices safe when connected wirelessly has become one of the major concerns.Quantum cryptography provides a solution towards absolute communication security over the network by encoding information as polarized photons, which can be sent through the air.This paper explores on the aspect of application of quantum cryptography in wireless networks.In this paper we present a methodology for integrating quantum cryptography and security of IEEE 802.11 wireless networks in terms of distribution of the encryption keys.
