| Jan 25, 2017 at 2:31 | comment | added | Paul Uszak | It may be worth clarifying that AES is a derivative of a SPN as there is also a round key factored in between substitutions and permutations. The round key allows a variable user key to be implemented, otherwise the SPN cipher would be hard coded and invariant. Consequently AES is not exactly a SPN per se, but rather founded upon one. | |
