New Encryption Standard and Particular Case of Blowfish Algorithm

Encryption algorithm plays a crucial role in information security which guarantees the recent growing internet and network applications. They are used to secure the data in wireless networks against malicious attacks but securing data also consumes resources such as C.P.U time, Memory, battery power, encryption time etc. Blowfish, a new secret-key block cipher, is proposed. It is a Feistel network, iterating a simple encryption function 16 times. The block size is 64 bits, and the key can be any length up to 448 bits. Looking at the current situation, our ambition is to tighten up the security factor that minimizes the effect of Cryptanalysis being done on Blowfish algorithm. Our new paradigm is having substantial amount of effort and an improvable aspect on security over the network. Although there is a complex initialization phase required before any encryption can take place, the actual encryption of data is very efficient on large microprocessors. This paper discusses the requirements for a standard encryption algorithm. Experimental results show that Blowfish encryption algorithm may be more suitable for wireless networks with secure data transmission. With reduced bits in plain text and key our aim is to make it useful for systems having minimum configuration.
