Abstract

Security systems are the need of the hour to protect data from unauthorized access. The dissemination of confidential information over the public network requires a high level of security. The security approach such as steganography ensures confidentiality, authentication, integrity, and non-repudiation. Steganography helps in hiding the secret data inside the cover media so that the attacker can be confused during the transmission process of secret data between sender and receiver. Therefore, we present an efficient hybrid security model that provides multifold security assurance. To this end, a rectified Advanced Encryption Standard (AES) algorithm is proposed to overcome the problems existing in AES such as pattern appearance and high computations. The modified AES is used for the encryption of the stego image that contains the digitally signed encrypted secret data. The enciphering and deciphering of the secret data are done using the Rivest–Shamir–Adleman (RSA) algorithm. The experiments are conducted on the images of the USC-SIPI standard image database. The experimental results prove that the proposed hybrid system outperforms other SOTA (state-of-the-art) approaches.
