Image Encryption based on AES Algorithm and XOR Operation

As the information trade in electronic way is quickly expanding, it is likewise similarly vital to shield the classification of information from unapproved get to. The breaks in security influence client's protection and notoriety. The information traded can be content, picture, sound, video and so on. Each sort of information has its own particular highlights and diverse methods are utilized to shield classified picture information from unapproved get to. Thus encryption of information is done to affirm security in open systems. Cryptography is the investigation of procedures for secure correspondence within the sight of a foe. It manages issues like encryption, validation, and key appropriation to give some examples. Image encryption is a system that gives security to pictures by changing over the first picture into a picture which is hard to get it. In the base paper, main approach was that they have added a key stream generator (A5/1W7) to AES to ensure improving the encryption performance; mainly for images characterized by reduced entropy. The implementation of both techniques has been realized for experimental purposes. Detailed results in terms of security analysis and implementation are given. Comparative study with traditional encryption algorithms is shown the superiority of the modified algorithm. But the comparative study showed that encryption time as well as decryption time of this algorithm is quite high. The parameters used in their research such as entropy, co-relation and PSNR are also needed to be analyzed. To improvise their algorithm, we have proposed an algorithm which deals with XOR operation of the sub keys. The methodology is described below.

Image security is important these days as data is increasing a lot. These data can be images, videos, text, audio, etc. so to protect these images from attackers who can destroy the image quality or modify the images, some technologies like AES, DES, RSA, etc. have been invented. With the generation, data security has also become an essential issue. Considering these issues, the proposed technique ensures confidentiality, integrity, and authentication. Using these techniques, the host can encrypt and decrypt the image and can keep the digital images safe. When AES was chosen 16 years ago, digital technology was completely different from today and the scale of challenges was smaller, so with recent advanced technology and the emergence of new applications such as Big Data applications, in addition to applications running with 64-bit and many other applications have become necessary to design a new current algorithm for current requirements. Advanced Encryption Algorithm (AES) is a symmetric algorithm, which we will further discuss in detail in our research, and in addition to new recommendations for future work, a list of shortcomings and vulnerabilities of the internal structure of the AES algorithm will be diagnosed.

Encryption of images has become a necessity in today’s world to protect a confidential image from unauthorized access. Various methods have been proposed and developed in spatial, frequency and hybrid domains to encrypt the image securely. Encryption could either be a full encryption or partial encryption based on the security requirements. In this paper we present an overview of various image encryption techniques based on AES.

Image encryption is one of the most methods of information hiding. A novel secure encryption method for image hiding is presented in this paper. The proposed method provides good confusion and diffusion properties that ensures high security due to mixing the two Boolean operations: XOR and Rotation that are done on the bits of the pixels in the image. This method is implemented by firstly doing a sequential XOR operation on all the bits of pixels in the image, and secondly makes a circular rotate right of these bits. These two operations are repeated many times during the encryption phase. The security and performance of the proposed encryption method have been evaluated by applying it on images and analyze the recorded results using key space analysis, key sensitivity analysis, and statistical analysis. The performance experiments show that the proposed method is promising to use effectively in wide fields of image encryption.

Data Security is primary concern for every communication system. The relentless growth of Internet and communication technologies has made the extensive use of images unavoidable. There are many ways to provide security to data that is being communicated. This Paper describes a design of effective security for communication by AES algorithm for encryption and decryption.

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 satisfactory security 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, a...
