Abstract:

One of the most difficult issues in the history of communication technology is the transmission of secure images. On the internet, photos are used and shared by millions of individuals for both private and business reasons. Utilizing encryption methods to change the original image into an unintelligible or scrambled version is one way to achieve safe image transfer over the network. Cryptographic approaches based on chaotic logistic theory provide several new and promising options for developing secure Image encryption methods. The main aim of this paper is to build a secure system for encrypt

Abstract:

The existing reversible data hiding methods in encrypted domain separate image encryption from information embedding and do not make full use of the redundant space in the process of image encryption. In order to improve the performance of reversible data hiding by using the technical characteristics of image encryption, a reversible data hiding method based on McEliece error correction is proposed. Firstly, the segmentation position of bit plane is determined according to the embedding requirement and texture characteristic, and the image is divided into high and low significant bits. Secondl

Abstract:

The scattering system through a highly scattering thin layer only affects the amplitude and phase distribution of incident light wave, but does not lead the total energy to be attenuated. This process can be regarded as a process that light wave is encoded by the scattering medium, which is similar to a double random phase encryption system. In this paper, firstly, it is proved that the distribution characteristics of speckle generated by the light wave carrying the target information through a strongly scattering thin layer are highly similar to the distribution characteristics of cyphertext

Abstract:

Digital data security has become very important in the current information era. One way to maintain data security is to use encryption and decryption techniques. The Advanced Encryption Standard (AES) algorithm has been proven effective in protecting data with a high level of security. This research aims to implement the AES-128 bit algorithm for online file encryption and decryption via a website. The method used in this research includes developing a website that provides a user interface for uploading and encrypting files, as well as for decrypting files that have been previously encrypted.

Researchers are increasingly interested in image encryption in the modern technological era. Their goal is to improve the security of image data from unauthorized sources. Due to its randomness and unpredictable behavior, chaos theory is considered the most suitable method for encrypting images. An image encryption algorithm based on diffusion maps is presented in this paper. An element of nonlinearity is generated by modifying the pixel values with a chaotic map first. Three chaotic maps are used in the proposed image encryption scheme. In an efficient encryption algorithm based on the improv
