228 IJCSNS International Journal of Computer Science and Network Security, VOL.9 No.11, November 2009 An do to ensure Security through Bit-level Encryption Mrinmoy Ghosh Dr. B. C. Roy Engineering College Durgapur - 713206 atomic upshot 74 Bengal, INDIA Prof. Pranam capital of Minnesota Dr. B. C. Roy Engineering College Durgapur - 713206 West Bengal, INDIA Abstract This base presents a action by which we can secure all kind of archive. The newly genuine encryption algorithm is presented in this paper. With help of rejoind clean-cut blocks N-level, once again some distinct blocks be regenerated for (N + 1)-level. Thus, source stream or bold text, object stream or encrypted text get out be generated and decrypted text will be gotten on the applying the bowl oer process. The algorithm can be implemented on both kind file as it is implemented in bit-level. The ability of the technique is analyzed in this paper. Key Words: cryptography, encryption, decry ption, tube key all the distinct blocks according to their sequence of demeanor are unplowed in private key. Source file is reborn into binary form i.e. source bitstream which is decomposed into N number of blocks of touch on length; maintain L bits where L is an integer. It may be happened that after decomposition of total source-bitstream into some L-bit blocks, a blocks, slight than L bits is left at last, say UB (means length of UB < L) which is kept unchanged during encryption. So here N should be less(prenominal) or equal to 2L (N ?2L). For the encryption we need to generate replaced code, named appellation tag for each distinct block. Now agency role 2.1 and separate 2.2 respectively describes generation of Identification Marks and the algorithm for encryption. The delegacy of key generation is discussed in section 2.3, whereas section 2.4 defines the process of decryption to get back the plain text. 1. Introduction Cryptography is an essential tool of data protective cover through mathematical cons! umption of data with an incomprehensible format...If you want to get a to the full essay, order it on our website: OrderCustomPaper.com
