Optical computing uses photons instead of electrons to perform computations, which can significantly increase the speed and energy efficiency of computations by overcoming the inherent limitations of ...

The circuit is driven by a MAX7219 IC that is being controlled through an Arduino microcontroller board, to create an 8X8 LED matrix. The connection of the LED matrix and the IC was done on a ...

In this paper, an encryption technique using matrix based substitution and diffusion for fast image encoding is discussed. The cryptographic procedure manipulates a two dimensional array (matrix) for ...
