Digital Image Encryption Based On Advanced Encryption Standard(AES) Algorithm

With the rapid development of network and communication technology, digital image communication has become an important way of information transmission. Therefore, much more attention has been paid to the development of the digital image encryption technology. In this paper, we propose a digital image encryption technology based on AES algorithm, and the algorithm implementation in MATLAB. Then, we perform digital image processing, obtain the date that can use the AES encryption algorithm, combine both approaches. Then, the digital image can be encrypted, and the algorithm is realized in MATLAB simulation. Through the comparison of the histogram analysis and the analysis of the key, the result has showed that the method can better realize the effect of encryption and decryption.
