The paper introduces work on developing secure data communication system. It includes the usage of two algorithms RSA and AES used for achieving cryptography along with LSB for achieving steganography both on Android platform. The joining of these three algorithms helps in building a secured communication system on ‘Android’ platform which is capable of withstanding multiple threats.
The input data is encrypted using AES with a user defined key prior to being embedded in image using LSB algorithm. The key used for encryption is further wrapped by means of receivers public key and that wrapped product key is further kept hidden so as to pass it to receiver that assure all the security purposes (RSA), making this a reliable communication channel for sensitive data. All stages assure that the secret data becomes obsolete and cannot be break easily; the steganographic algorithm thus introduces an additional level of security.
