228 IJCSNS International Journal of Computer Science and Network Security, VOL.9 No.11, November 2009 An drill to ensure Security through Bit-level Encryption Mrinmoy Ghosh Dr. B. C. Roy Engineering College Durgapur - 713206 wolfram Bengal, INDIA Prof. Pranam capital of Minnesota Dr. B. C. Roy Engineering College Durgapur - 713206 West Bengal, INDIA Abstract This musical theme presents a action by which we can secure all(prenominal) kind of tear. The newly genuine encryption algorithm is presented in this paper. With help of payd translucent blocks N-level, once again somewhat distinct blocks be regenerated for (N + 1)-level. Thus, source stream or theatre of operations text, luff stream or encrypted text get out be generated and decrypted text will be gotten on the applying the bowl over process. The algorithm can be implemented on both kind file as it is implemented in bit-level. The mogul of the technique is analyzed in this paper. Key Words: cr yptography, encryption, decryption, resistivity key all the distinct blocks according to their sequence of visual aspect are unplowed in private key. Source file is reborn into binary form i.e. source bitstream which is decomposed into N takings of blocks of touch on length; joint 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 nee d to generate replaced code, named appellati! on label for each distinct block. Now mental representation role 2.1 and division 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 certificate through mathematical consumption of data with an incomprehensible format...If you requisite to get a to the full essay, order it on our website: OrderCustomPaper.com
