<br/><br/>Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Mathematics and Physics 
<br/><br/> This thesis introduced seven new encryption designs based on different methodologies such as: chaotic differential equations of integer and fractional-orders, nonlinear generalized chaotic maps, fractals with their fine details, mixing the generalized Fiestel network with the Linear Feedback Shift Register (LFSR) and, also, a new encryption system based on the chess-based horse-move to generate the permutation matrix. Many standard images were discussed and evaluated using the international measures such as NIST. Seven international papers were published (2 journal papers with IF + five international conferences)
