Paper Title
Hybridization of SHA-256 and MD5 Hashing Techniques with AES to Enhance Image Encryption

Images are usually encrypted in order to hide the visual information when transmitted over an unsecure channel. The latter can be subject to many attacks and thus a reliable as well as an efficient mechanism has to be deployed for such task. For the sake of protecting data while being transmitted, multiple encryption techniques have been implemented some of them are secure but time consuming, while some others are efficient and fast. In our paper, we focus on image encryption, and we introduce multiple techniques based on AES, hash functions, and block selection variations. Experiments showed very promising results compared to the original AES in terms of encryption/decryption time while maintaining almost the same level of security.
