Teaching Cryptography: Rubik's Cube Diffusion
Written by Dominik Joe Pantůček on 2019-05-16
Although we are dealing mostly with asymmetric encryption here at Trustica, truth is that in the end you need to encrypt stuff using some symmetric algorithm. Just exchanging the symmetric keys is not enough - the symmetric cipher must be built from strong cryptographic primitives creating both confusion and diffusion. Read on to find out what one of my Cryptography class students proposed.
