Simulated Analysis and Enhancement of Blowfish Algorithm
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2015, Vol 17, Issue 6
Abstract
Abstract: This paper represents or analyzes the security of system based on Blowfish. Blowfish mainly focuses on the encrypt and decrypt techniques and algorithms apply for cryptanalysis. It describe the algorithms for encryption as well as decryption algorithms and also give the sufficient description of key generation, key expansion, function and working principle of Blowfish cipher with proper explanations. Taking the current era, Most of the famous systems which offer security for a network or web or to a data are vulnerability to attacks and they are broken at some point of time by effective cryptanalysis methods, irrespective of its complex algorithmic design. In the general, today’s cryptography world is bounded to an interpretive of following any one or multiencryption scheme and that too for a single iteration on a single file only. This is evident in the maximum of the encryption-decryption cases. It also describes the comparisons between older blowfish and enhances blowfish. Italso shows enhance Blowfish algorithm for encryption and decryption of data. It is also give the proper simulated analysis of encryption and decryption time for different file formats using a windows application. It describe feature of application and its process and efficiency as well as calculation of time and throughput.
