Abstract

Secure and reliable image transmission is critical in modern communication systems. This project presents a hybrid encryption scheme that integrates a chaotic system with Elliptic Curve Cryptography (ECC) to enhance the security and quality of image transmission. The proposed method utilizes chaotic maps to introduce high randomness, which is further reinforced by ECC-based key generation via the Diffie-Hellman algorithm. XOR-based encryption with pixel grouping is applied for increased resistance against statistical attacks. The system's GUI facilitates user interaction for uploading images, generating secure keys, encrypting, decrypting, and comparing results. Experimental outcomes demonstrate that the proposed approach significantly improves image quality after decryption, as evidenced by higher PSNR and SSIM values compared to existing techniques. Visual comparisons also reveal a substantial improvement in preserving the original image content, making this method highly effective for secure image transmission.
