AES Based Image Encryption and Decryption for Secure Data Transfer

Abstract: With the rise of digital communication, ensuring secure image transmission is crucial to prevent unauthorized access and cyber threats. The Advanced Encryption Standard (AES) is a powerful symmetric encryption algorithm that efficiently encrypts and decrypts image data, ensuring confidentiality and integrity. This paper explores the implementation of AES for secure image transfer, transforming pixel values into encrypted form to prevent interception. The decryption process accurately restores the original image using the same key. Performance metrics such as encryption speed, key sensitivity, and resistance to attacks are analyzed. While AES is highly secure, challenges like computational overhead necessitate optimization and hybrid encryption approaches. Future research aims to enhance AES with AI, blockchain, and quantum cryptography for improved security and efficiency.
