\item T/F: If \tta\ and \ttb\ are square matrices where $\tta\ttb=\tti$, then $\ttb\tta=\tti$. \item T/F: A matrix \tta\ has exactly one inverse, infinite inverses, or no inverse. \item T/F: Everyone ...
Abstract: Developers are often limited to the use of low order matrix keys when the Hill cipher is embraced. This is due to the complexity of determining matrix inverses when high order matrices are ...
In this paper, an image encryption algorithm based on the H-fractal and dynamic self-invertible matrix is proposed. The H-fractal diffusion encryption method is firstly used in this encryption ...
