摘要：Recently, many studies has been shown that the image encryption could be done using some techniques like RES, DES, IDEA but the new and effective technique for speedy and secure encryption using chaos-based cryptography is the most preferred encryption technique. Chaos-based encryption algorithms are a hybrid technique of multiple chaotic maps and can be repeated the same process for multiple cycles to increase the security. But, the increasing the number of steps to process an image will increase the processing time too. Another reason, if the number of pixels being encrypted increased will increase the processing time. Since, chaos-based algorithms are selected as a good choice for encrypting images during the real time applications, lesser response time and even the higher security are important. This paper will focus on evaluating encryption techniques by using two dimensional chaotic maps and comparing the strength of the encryption algorithms security and the time responses for many images have different sizes. Finally, quantitative results are compared evaluated and implemented of the serial implementation, parts of encryption and decryption process that can be parallelized (using GPU and CUDA programming) with the serial implementation.
