A Chaotic-Based Encryption/Decryption Framework for Secure Multimedia Communications based on MBMES and DNA encoding

Abstract

To offer a safe method of sending multimedia data over the Internet, a Chaotic-Based Encryption/Decryption Framework for Secure Multimedia Communications is developed. The suggested system uses the hybrid encryption technique known as MBMES, which combines the benefits of block cyphers and chaotic maps. Various multimedia data formats, including photographs and movies, were used to evaluate the suggested framework, and the findings revealed that it offered high levels of security with little computational overhead. It is suitable for real-time multimedia applications since the encryption and decryption are quick and effective. The plaintext image's pixel values and the related DNA encoding/decoding rules are mapped in the encryption process to allow for dynamic changes in the relationship between them. Attackers find it challenging to use known plaintext data to crack additional images due to the adaptability of the encoding/decoding methods based on the image's content. This function offers high protection, essential for safeguarding sensitive multimedia data. The dynamic DNA-based encryption technique ensures secure communication by fusing the benefits of chaotic-based encryption, DNA coding, and dynamic rule adaptation.
