228 IJCSNS International Journal of Computer Science and Network Security, VOL.9 No.11, November 2009 An example to ensure Security through Bit-level Encryption Mrinmoy Ghosh Dr. B. C. Roy Engineering College Durgapur - 713206 due west Bengal, INDIA Prof. Pranam capital of Minnesota Dr. B. C. Roy Engineering College Durgapur - 713206 West Bengal, INDIA Abstract This newspaper presents a action by which we can secure whatsoever kind of file cabinet. The newly genuine encryption algorithm is presented in this paper. With help of spawnd decided blocks N-level, once again some(prenominal) distinct blocks be regenerated for (N + 1)-level. Thus, source stream or flying field text, patsy stream or encrypted text get out be generated and decrypted text will be gotten on the applying the bowl all over process. The algorithm can be implemented on any kind file as it is implemented in bit-level. The force of the technique is analyzed in this paper. Key Words: cryptography, encryption, decryption, pipe key all the distinct blocks according to their sequence of appearing are unplowed in private key. Source file is reborn into binary form i.e. source bitstream which is decomposed into N military issue of blocks of touch on length; show 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! mark for each distinct block. Now delegacy role 2.1 and partitioning 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 credential through mathematical consumption of data with an incomprehensible format...If you deficiency to get a to the full essay, order it on our website: OrderCustomPaper.com
