Hindmarsh-Rose Model for Efficient Image Encryption

الملخص

Image is one type of multimedia data that is shared via networks and social media, to secure it needs an effective method for confidentiality. Image encryption is a powerful and effective tool for protecting visual data in an era of increasing reliance on technology and the propagation of security threats. With advances in encryption algorithms, it has become possible to secure images while maintaining system performance effectively. As the importance of visual data continues to grow, image encryption will remain a key component of information security strategies. An efficient method for color image encryption based on Hindmarsh-Rose map is proposed. The method used a dimension sequence for different stages of the encryption algorithm such as the first sequence used in block permutation, the second dimension used in S-boxes generation, and the third sequence used in the diffusion process. The proposed method results in accurate results in terms of visualization tests, objective tests, correlation tests, key space analysis, and randomness tests. The proposed method could be applied for audio and video encryption.
