Secured transmission of data is an important technological issue in the world. It is very much essential to develop intelligent cryptographic algorithm, which solves this purpose. A bit shifting and stuffing (BSS) system refers to shifting the printable character bits (ASCII characters of 7 bits each) by 01 bit. The 8th bit of one printable character is replaced by a new bit of other printable character. In the BSS system based encryption process, for every eight bytes of plain text of data in encryption pr ocess; the encryption produces seven bytes of cipher text. On contrary during decryption process, seven bytes of cipher text converted to original eight bytes of plain text. In this work a new replacement algorithmic rule for Digital encoding called as “Bi t shifting and Matrix XOR Operation Conversion Technique” (BSMXOR) is proposed which increases the complexity of encryption of the data. The experimental results shows that the new theme has very fast encoding and safer for data transmission
