Use of Symmetric Algorithm for ImageEncryption

In this paper we present image encryption using symmetric algorithm (SA). Encryption is a method to protect data against destruction by involving special algorithm and keys to transform digital data into unreadable format before transmission over the network. The Decryption keys are used to get the original digital data back from the transmitted encrypted data form. Data encryption standard (DES) is one of the symmetric algorithms. This paper presents an analysis on DES algorithm for image encryption. The proposed idea will reproduce the original image with no information loss. A comparative study of the DES algorithm with the present image encryption algorithms is also done in this paper.
