Comparison of Cryptographic Techniques: Classical, Quantum and Neural

Now days, the necessity of highly secured and reliable network is tremendously increased in the wireless communication network. There are various routing attacks occurs in wireless communication network there for secure routing is one of the most challenging research area in a mobile ad-hoc network-MANETs. Several methods are available for providing safety of the MANET, still various attacks are there which reduces network performance. Hence a strong cryptography technique is required to secure communication in MANET. An efficient cryptographic method is required, which will not only generate and maintain key also distribute it safely to the nodes which are not malicious. The method proposed here detects the nodes which are malicious and keeps them away from communication in the network so that packet delivery rate is increased by reducing delay in the network. The reliable communication in MANET is achieved by applying strong cryptography methods. In this paper comparison of classical, quantum and neural cryptography are given.
