Design and Analysis of Complex Data Security Algorithm Using Cryptography and Steganography Techniques

This paper aims to provide a security solution for 256-bits digital data using Cryptography andSteganography techniques during its transmission over the digital network. The Cryptography technique has been implemented using a newly developed data security algorithm having various operations on the data and the keys and the Steganography technique has been implemented using data cover process. In order to check the integrity of the data, the data integrity check has been done so as to ensure that the data has not been modified by the attacker during itstransmission. The proposed algorithm is found to be resistant towards various types of attacks such as Brute-force attack, timing attack etc. The maximum combinational path delay of the data security unit is 10.052ns
