Robust Dynamic Key Generation
The proposed mechanism integrates fractional-order chaotic systems with SHA-256 to dynamically generate high-quality, unpredictable random number sequences. This approach ensures robust cryptographic keys and initialization vectors for secure image encryption, significantly enhancing the difficulty for brute-force attacks.
Seamless Chaotic System Synchronization
A crucial synchronization controller is designed to ensure master-slave fractional-order chaotic systems generate identical dynamic keys without explicit transmission. This resolves traditional key distribution challenges, simplifies key management, and enhances overall system security by preventing key interception.
Advanced Image Encryption Transmission
The system employs AES-CFB mode with dynamically generated keys and IVs for block-wise image encryption. This design significantly reduces inter-block correlation, enhances diffusion across the image, and provides strong resistance against statistical and differential attacks, making the ciphertext visually indistinguishable from noise.
Validated Security & Performance
Quantitative evaluations using NIST SP 800-22, ENT, and DIEHARD validate the high randomness of generated keys. Encrypted images exhibit uniform histograms, near-ideal Shannon entropy, and significantly reduced pixel correlations, demonstrating superior security and efficiency compared to recent related works.
