Afiya Amjed, Jalesh Kumar · 2023
Secure multimedia transmission is one of the challenging conditions in the age of communication technology. To achieve a secure multimedia transaction encryption can be used which preserves the confidentiality, integrity, and authenticity of multimedia content (such as images, videos, and audio) during digital transactions. Encryption techniques that transform original image into an unintelligible or scrambled form, known as a cipher image, are one way to achieve secure image transmission over the network. This way, even if the attacker gains access to the cipher, they would not be able to retrieve the real image. Chaos-based encryption is a cryptographic technique that uses chaotic systems inherent unpredictability and sensitivity to beginning conditions to generate encryption algorithms. This study enables the implementation and analysis of chaos-based picture encryption algorithms for image encryption. A chaotic system, such as the logistic map or the Lorenz system, is used to generate chaotic value sequences. These systems are extremely sensitive to beginning conditions, making it difficult to predict their future states. As a native chaotic and hybrid chaotic techniques, Arnold cat map, Henon map and Tent map are utilised in security models this offers an option for improving the protection of multimedia information in an increasingly linked environment. The experimental results shows that the proposed system work satisfactorily.
