A New Stegano-Cryptographic Approach for Enhancing Text Data Communication Security

As the use of smartphones, laptops, and computers grows, these devices have become indispensable in our daily lives. We are exchanging a great deal of data via the Internet. Many of this data are very confidential, which include banking credentials, national secrets, and defence strategy, among other things. Steganography and cryptography are two fundamental areas of security that deal with delivering information or data via media like the Internet. Steganography is known as concealing information in a message, while cryptography is the method of encrypting the message. They are both utilized to keep things safe. However, none of them can easily meet the basic security requirements, such as robustness, undetectability etc. As a result, a new technology known as Stegano-Cryptography is being developed, which combines steganography with cryptography to overcome each other's shortcomings and make it harder for attackers to assault or steal important information. This paper proposes a new method where a text is first turned into a stego object using a suitable steganographic technique, and then the stego object is encrypted using the AES encryption algorithm. Thus, this approach can enhance the security of text data communication.
