Abstract
This paper presents a process by which we can secure any kind of file. The newly developed encryption algorithm is presented in this paper. With help of generated distinct blocks N-level, again some distinct blocks are regenerated for (N + 1)-level. Thus, source stream or plain text, target stream or encrypted text will be generated and decrypted text will be gotten on the applying the reverse process. The algorithm can be implemented on any kind file as it is implemented in bit-level. The strength of the technique is analyzed in this paper.

Cryptography is an essential tool of data security through mathematical manipulation of data with an incomprehensible format for unauthorized person. Here a newly developed technique named, Replacement of Cyclic Regeneration of Distinct Block (RCRDB) is discussed. At first, plain text is decomposed into some blocks, having equal length. With help of all distinct blocks, some distinct blocks have been regenerated. The process will be continued up to a finite level of regeneration. Finally by rearrangement and replacement of all blocks in source stream or plain text, target stream or encrypted text will be generated. Hence getting source stream and the privet key, decrypted text will be gotten on the applying the reverse process.
Section 2 presents the scheme followed in the encryption technique. Section 3 describes an implementation of the technique. Section 4 presents results of executing the technique on some real files. Section 5 is an analytical discussion on the technique with a conclusion.
