|Title:||Ensuring information security through 123-bit recursive substitution of bitsthrough prime-nonprime detection of sub-stream (RSBP)|
Mandal, Jyotsna Kumar
|Abstract:||This paper presents a 123-bit private-key based block-cipher, RSBP, which is capable of encrypting files of up to 11 MB.It is formulated on the basis of base-10 value corresponding to a block of bits, which is to be checked if is prime or not. It resultsin an alteration of size for file being encrypted. Its executable performance is analyzed on the basis of execution time, graphicallayout of frequency distribution of characters, and Chi square values for varying degrees of freedom. RSBP is found to behighly compatible with existing cryptosystems.|
