Can anyone in 6th grade English explain the steps in the Substitution-permutation network algorithm or just point a link that does so? (which is included in many of the top modern algorithms)

Wikiepedia's link is not really that helpful and I can not locate anything simple on the internet for beginners.

  • $\begingroup$ youtube.com/watch?v=mlzxpkdXP58 has a nice animation for AES as an example.. $\endgroup$ – Henno Brandsma Feb 22 '15 at 14:32
  • $\begingroup$ Thanks @HennoBrandsma I still did not move to AES. I want to master the SPN at first. $\endgroup$ – tony9099 Feb 22 '15 at 14:37
  • $\begingroup$ It's IMHO probably best understood by an example. $\endgroup$ – Henno Brandsma Feb 22 '15 at 14:38
  • $\begingroup$ @HennoBrandsma do you know any link that provides a nice example ? $\endgroup$ – tony9099 Feb 22 '15 at 14:55

    $\begingroup$ I don't think that an example like AES is good. It's to complicated. In my opinion is the graphic on the right site of the wikipedia article a good example for a substitution permutation network. It's descripes exactly what a SPN is. $\endgroup$ – Nova Feb 22 '15 at 20:30
