I would like to design a cryptographically secure, key-dependent s-box, but I am not sure how. Mainly, because I am unsure about the difference in design compared to a random s-box.

What is the difference between the methods of S-box construction of “key-dependent s-boxes” and “random s-boxes”?

You might find a few hints at “Desirable S-box properties” and/or “S-box design criteria and random sboxes”. – e-sushi Jul 22 '15 at 23:49
