Random Bit Generator Mechanism Based on Elliptic Curves and Secure Hash Function
O. Reyad, M. E. Karar, K. Hamed
Pseudorandom bit generators (PRBG) can be designed to take the advantage of some hard number theoretic problems such as the discrete logarithm problem (DLP). Such type of generator…

A Novel Image Encryption Scheme Based on Different Block Sizes for Grayscale and Color Images
Omar Reyad, M. A. Mofaddel, W. M. Abd-Elhafiez +1
In this paper, two image encryption schemes are proposed for grayscale and color images. The two encryption schemes are based on dividing each image into blocks of different sizes.…
