Multimedia security is an important field of research in the area of information sharing. In this paper, Fast Encryption Algorithm (FEAL), an encryption/decryption strategy for gray scale images is proposed. The FEAL is a block cipher, also called as Japanese Encryption algorithm. FEAL works almost similar to Data Encryption Standard (DES) algorithm, but it is faster than DES. To encrypt the images, the input image is split into 16x16 blocks of information. Encryption/Decryption is carried out using 12 keys, each of length 16-bits. The proposed image encryption algorithm is evaluated based on histogram analysis and key sensitivity analysis and results obtained are satisfactory.
