A Chaotic-Based Image Encryption System Integrated with Blockchain for Secure Data Transmission
Ahmed Alshammari · International Journal on Information Technologies and Security · 2025
In this research, we present an exploration of encryption cryptosystem that integrates chaotic systems and blockchain technology to protect the privacy of your information and ensuring that its trustworthy. The system applies Chua's system, a communally known chaotic model, besides a Bernoulli binary generator to make a robust chaotic sequence for encrypting images. Blockchain technology further strengthens security by maintaining the picture's integrity hash and decryption key inside the blockchain, to make sure the encryption keys are tamper-resistant and sustain an immutable record for secure access and recovery. Additionally, the encryption process manufactures about 1-million-bit stream, which successfully passes NIST tests, confirming the randomness and security of the bit stream and refine the cryptosystem's general robustness. This method offers a great degree of security for sensitive and medical image data, protecting confidentiality and integrity via the incorporation of chaotic encryption, blockchain-based key management, and conforming random bit streams. The system is ideally designed to safeguard the image transmission in fields such as telemedicine and other healthcare-related applications.
