Secure Medical Multimedia Data Using Symmetric Cipher Based Chaotic Logistic Mapping

Multimedia security has become a serious issue in this digital world, as more and more industries and people are turning towards digitalization. The existing encryption standards are successful in securing textual data but are not very effective for safeguarding multimedia data like images and videos. This stimulates the urge for development of new encryption systems and tools that can address the multimedia security issue. In this work we present a multimedia encryption mechanism that secures multimedia data with the help of chaotic logistic map and linear feedback shift register (LFSR). The use of chaotic map helps in providing the confusion and diffusion properties required for the encryption algorithm and also make it robust and efficient. The experimental results and analysis show that it exhibits high entropy, security against various cyber-attacks and also has lesser time and space complexities than existing techniques.
