摘要：In the era of computer and internet technology, multimedia protection is becoming increasingly jeopardized. Therefore numerous ways of protecting information are being utilized by individuals, businesses and governments. This paper mainly focuses on a new AES a based image encryption technique using binary code which is expected to provide safety of images travelling over the internet. In order to evaluate the performance, the proposed image encryption technique was measured through a series of tests. These tests included a histogram analysis, information entropy, correlation analysis and differential analysis. Experimental results showed that the proposed encryption technique has satisfactorysecurity and is more efficient than using the AES algorithm alone which makes it a good technique for the encryption of multimedia data. The results showed that the histogram of an encrypted image produced a uniform distribution, which is very different from the histogram of the plain image, and the correlation among image pixels was significantly decreased by using the proposed encryption technique and higher entropy was achieved.
