The most significant and fundamental problem in the field of message transmission through networks is secure data communication. Cryptography enables the creation of secure messages for the transportation of secure messages. By transforming the sender’s message into a secret format known as cypher text, only the intended receiver will be able to comprehend the secret message's meaning. To hide a message’s content and its underlying meanings, utilize steganography and cryptography respectively. The message is first encrypted using the Vernam encryption technique, and then it is integrated (encrypted) in the image using a new image steganography method called Least Significant Bit (LSB) with Shifting (LSB-S). Using a pixel's four LSBs, the LSB-S technique executed a left rotation operation and an XOR operation. The use of encryption and steganography together improves the security of hidden message. Following the suggested method's implementation, it was checked against several parameters and gave positive outcomes. To generate hidden messages for communication, several DNA based encryption or scrambling algorithms have been developed. But, all of the suggested DNA-based encryption algorithms are secure enough to provide better security than what is provided today. In this paper, they present the creation of a new LSB-S image steganography approach based on Galois-field
