Abstract: The main objective of this study is to detect the existence of secret information hidden within an image. Cryptography is one of the most interested and important area in the computer industry that deals with secures transmission of information. Encryption, the process, which helps for such secure transmission prevents hackers to access the information. And decryption helps to retrieve the original information. Cryptography provides many methods and techniques for secure communication. Currently, there are many industry standard encryption/decryption algorithms including RSA, AES, Robust Security Network (RSN), blowfish and so forth. However, they are fairly complex and require that one spend a lot of time to comprehend and implement them. This study introduces simple Encryption/decryption algorithm that is high-speed and practically make safe. The algorithm manipulates a 128-bit input using flipping, substitution and permutation to achieve its encryption/decryption.
