The Role of Quantum Cryptography under Distributed Protocols for Secured Communication in Ad Hoc Networks

Most of the cryptographic methods employed so far has been using symmetric and asymmetric cryptography, and had involved cryptographic keys extensively. Usually it is observed that many of the cryptographic algorithms are infeasible as the key distribution system is feeble. As an emerging approach Ad Hoc networks is subjected to Quantum cryptography concept or quantum key distribution in distributed environment and has drawn a good attention as an appropriate solution to the Key Distribution issue. QKD extends unconditional secured inter-communication by means of quantum mechanics. The paper focuses on quantum theory as a substitute to conventional key distribution protocols and a comprehensive narration is offered illustrating implementations of quantum key distribution protocols. This paper depicts quantum key distribution protocols (QKDP) to preserve safety in large and Ad hoc networks, guiding towards novel direction. It is aimed to narrate the efficiency of communication in terms of effort, security, suitability and confidentiality by the use of QKDPs
