An Image Encryption Technique to Remove the Drawback of the One-Dimensional Scrambling Method of Image Encryption

Image Encryption Using Block Scrambling Technique

Due to the rapid growth of digital communication and multimedia application, security becomes an important issue in data exchange process over the wide network. In this paper, an efficient technique is presented with the help of cipher block chaining (CBC) operation ,which is used for image encryption. We test our proposed technique using MATLAB R2010a, it can achieve various image quality para...

Effect of Pixel Scrambling Method on Image Encryption

Image Encryption using Curved Scrambling and Diffusion

In the recent world, designing of a secure cryptosystem is prime focused area for the researchers. This paper emphasizes on the image encryption/decryption technique using a key derived from a plain image. In the proposed algorithm, encryption key is derived by applying new curved scrambling method to the RGB layers of a plain image. In next step, a temporary cipher image is obtained by modulo ...

Permutation based Image Encryption Technique

Information security is the key in the era of electronic data exchange. Images constitute a large portion of the electronic data. Confidentiality of color images is a difficult process. Most of the image encryption algorithms are complex and compromise on the quality of the image. This paper proposes a new image encryption based on random pixel permutation with the motivation to maintain the qu...

On the security of an image encryption method

The security of digital images attracts much attention recently, and many different image encryption methods have been proposed. In 1999, J.-C. Yen and J.-I. Guo proposed a novel image encryption algorithm called BRIE (Bit Recirculation Image Encryption). This paper points out that BRIE is not secure enough from strict cryptographic viewpoint. It has been found that some defects exist in BRIE, ...
