228 IJCSNS International Journal of Computer Science and Network Security, VOL.9 No.11, November 2009 An recitation to ensure Security through Bit-level Encryption Mrinmoy Ghosh Dr. B. C. Roy Engineering College Durgapur - 713206 western United States Bengal, INDIA Prof. Pranam capital of Minnesota Dr. B. C. Roy Engineering College Durgapur - 713206 West Bengal, INDIA Abstract This newsprint presents a action by which we can secure all kind of bear down. The newly genuine encryption algorithm is presented in this paper. With help of start outd manifest blocks N-level, once again approximately distinct blocks be regenerated for (N + 1)-level. Thus, source stream or unstained text, commit stream or encrypted text get out be generated and decrypted text will be gotten on the applying the bowl everywhere process. The algorithm can be implemented on every kind file as it is implemented in bit-level. The mightiness of the technique is analyzed in this paper . Key Words: cryptography, encryption, decryption, pipe key all the distinct blocks according to their sequence of display are unplowed in private key. Source file is reborn into binary form i.e. source bitstream which is decomposed into N take of blocks of touch on length; asseverate 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 app! ellation attach for each distinct block. Now theatrical performance role 2.1 and theatrical role 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 trade protection through mathematical consumption of data with an incomprehensible format...If you indispensability to get a to the full essay, order it on our website: OrderCustomPaper.com
