A Random PRESENT Encryption Algorithm Based on Dynamic S-box

Optimization of AES Encryption Algorithm with S- Box

In any wireless communication, security is crucial during data transmission. The encryption and decryption of data is the major challenge faced in the wireless communication for security of the data. These algorithms are used to ensure the security in the transmission channels. Similarly hardware utilization and power consumption are another major things to be considered since most of the mobil...

An Image Encryption Algorithm with XOR and S-box

This new algorithm performs lossless image encryption by combining variable-length key-dependent XOR encryption with S-box substitution. This algorithm was implemented and tested by performing different permutations of XOR encryption and S-box substitution. Empirical analysis using different types of test images of different sizes showed that this new algorithm is effective and resistant to sta...

Parity Based Fault Detection Techniques for S-box/ Inv S-box Advanced Encryption System

Concurrent fault detection plays a vital role in hardware implementation in order to prevent losing the original message This paper explores the new low-cost fault detection scheme for the S-box/ InvS-box of AES using a parity prediction technique. The predicted block was divided into seven blocks, to compare between the actual parity output and the predicted parity output results in the error ...

A stack-based chaotic algorithm for encryption of colored images

In this paper, a new method is presented for encryption of colored images. This method is based on using stack data structure and chaos which make the image encryption algorithm more efficient and robust. In the proposed algorithm, a series of data whose range is between 0 and 3 is generated using chaotic logistic system. Then, the original image is divided into four subimages, and these four i...
