摘要：Fast Encryption Algorithm (FEAL) is an encryption/decryption technique used for the encryption/decryption of the grey scale images only. In this paper, FEAL is used for the encryption/decryption of colour images and text. In this, the key generation system for FEAL algorithm is updated using the XAND gate. By using the XAND gate, data cannot be deciphered using partial knowledge of key. This proposed system can also work upon the text data, which is firstly converted into bit sequence before making it an encrypted text. The comparison of the existing FEAL and proposed FEAL shows that the time taken by the proposed FEAL for the encryption /decryption of the grey scale image is less than that of the existing FEAL. To perform this research a simulation study is done using MATLAB. Along with this, JAVA is also used for obtaining the GUI as the applied for the results. The comparison of existing FEAL is done with the proposed FEAL on the basis of taken by the image to encrypt/decrypt. All the results are generated above defined simulator and are satisfactory.
