A Hybrid Cryptography Procedure to Achieve Security in Communication Network

Abstract

The digital communication technology offers efficient communication with low cost. It
turn into much prevalent communication technique now a days. The internet based
communication is one of the source of digital communication .The significant amount of
data carries in network as well as some of the data is much sensitive and private. The
attackers are tries to break the existing network security and recuperate the sensitive
information. So there is necessity to enrich security during the network based
communication. In our proposed work, using cryptographic technique the security is
enhanced either by enhancing the technique of key generation or modification on the key
policies or by improving the cipher generation process. In our work both kinds of
improvements are made to improve the security of data using cryptographic
techniques. The proposed hybrid cryptographic technique involves goodness of MD5
hash generation algorithm and the DES algorithm. The RSA algorithm is worn to
encrypt the key and to defend it while data is traversed through communication
network.. Then the cipher text and encrypted key is sent securely to the user in Digital
Envelope. According to survey of different cryptographic techniques both the
cryptographic techniques are proficient and sheltered for cipher generation purpose.
