To provide security in data communication networks various forms of cryptographic and steganographic algorithms have been proposed. Though both of these techniques serve the same purpose i.e. to secure data but have some drawbacks. Using cryptography might raise some suspicion whereas in steganography the distortion in cover can attract an adversary. The combinations of the two as proposed by various researchers can be very fruitful in terms of brute force search time and robustness against attacks. A popular method of combination is using pseudorandom Least Significant Bit (LSB) substitution along with stream cipher or block cipher.
