Abstract :
In recent years, image encryption has grown much to provide information security to end user. There are various algorithms for encrypting the image. RC5 is a block cipher and can be used for image encryption. In this paper, weaknesses of RC5 for image encryption are discussed and analysed. Further, improvement in RC5 algorithm is done. Improvement shows the robustness of algorithm against different attacks. Implementation of enhanced RC5 algorithm has been done on Matlab R2009a and tested with NIST randomness test suit and obtained satisfactory results.
