This paper presents a novel image encryption and decryption algorithm that combines chaotic systems and RSA cryptography to enhance the security of digital images. In this hybrid approach, a chaotic system generates a pseudo-random key for pixel-level encryption, while RSA cryptography is employed to securely exchange the encryption key between the sender and receiver. The proposed algorithm leverages the unpredictability and sensitivity of chaotic systems to obfuscate image patterns, ensuring high security against potential attacks. RSA cryptography, known for its robust public-key infrastructure, guarantees secure key management and protects the encryption key during transmission. Experimental results show that the algorithm offers strong encryption, high resistance to common cryptographic attacks, and efficient performance. The proposed method demonstrates the effectiveness of combining chaotic systems and RSA for digital image protection, making it a promising solution for applications requiring secure image communication and storage.
