Block cyphers are the most used type of encryption technique. This type of encryption technique takes as input a defined size of data, such as b bits, and outputs as output another block of data of the same size as the input.8) Cipher block chaining or CBC is an advancement made on _...
Abstract Visual cryptography is an encryption technique that decomposes secret images into multiple shares. These shares are digitally or physically overlapped to recover the original image, negating the need for complex mathematical operations or additional hardware. There have been many variations of visu...
