This paper proposes a computationally efficient method for securing information using “SECURING MESSAGE USING RECURSIVE MODULO-2 AND KEY ROTATION OPERATION (RMRO)”. A block of n bits is taken as an input stream, where n varies from 4 to 256, from a continuous stream of bits and the technique operates on it to generate the intermediate encrypted stream. This technique directly involves all the bits of blocks in a boolean operation and a session key. The same operation is performed repeatedly for different block sizes as per the specification of a session key to generate the final encrypted stream. It is a kind of block cipher and symmetric in nature hence, decoding is done following the same procedure. A comparison of the proposed technique with existing and industrially accepted RSA and TDES has also been done in terms of frequency distribution and non homogeneity of source and encrypted files.
