Article Synopsis
- An improved Josephus ring-based permutation (IJRBP) algorithm is introduced to enhance the existing permutation algorithms by replacing the traditional remove operation with position exchange and using random rather than fixed steps for better scrambling and efficiency.
- A new encryption algorithm is created using the IJRBP along with a chaotic system, leveraging a plaintext feature parameter to generate a diffusion matrix that ensures even slight changes in the source image result in drastically different encrypted images.
- This approach effectively balances sensitivity to plaintext and ciphertext, making it robust against chosen-plaintext attacks (CPAs) and capable of resisting noise attacks and data loss, as shown in successful simulation results demonstrating high encryption efficiency.
