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...

It describes an improved encryption algorithm of a three-dimensional image based on multiple chaotic systems. The algorithm uses a variety of chaotic encryption system to cut the image into three-dimensional matrix systems, in three-dimensional space do the image scrambling transformation, three-dimensional chaotic sequence output by multiple chaotic systems achieved three color pixel substitut...

The different methods for encryption and decryption in digital images have received growing attention recently. This is due to the availability of new editing software, sophisticated digital cameras, and in addition to tremendous development in communication networks including the Internet, which used by many people to send and receive various types of data including digital images, Although th...

‏‎for the first time nakayama introduced qf-ring. in 1967 carl. faith and elbert a. walker showed that r is qf-ring if and only if each injective right r-module is projective if and only if each injective left r-modules is projective. in 1987 s.k.jain and s.r.lopez-permouth proved that every ring homomorphic images of r has the property that each cyclic s-module is essentialy embeddable in dire...
