With the ever increasing growth of multimedia applications,security is an important issue in communication and storage of images. Encryption is one of the ways to ensure security.Image encryption techniques try to convert original image to another image that is hard to understand. There are various techniques which are discovered from time to time to ecrypt the images to make images more secure like Key Generation using Genetic algorithm,Secure force algorithm,Block based transformation algorithm etc. In this paper,a low complexity symmetric cryptographic algorithm denoted as Secure Force With Affine Transform has been proposed. The encryption part can be implemented by using simple architecture that only consists of basic mathematical operations (AND, OR,XOR,XNOR,SHIFTING,SWAPPING).This can help to reduce the burden on encoder,because the more complex key expansion process is only carried out at the decoder. The objective of this paper is to perform security analysis and performance evaluation of the proposed algorithm. Results of the proposed algorithm have been tested upon different kinds of images and comparitive analysis with other techniques has been presented.
