Are you sure that this is not Tuchman, IBMer who pushed LUCIFER into becoming DES and did a lot of the interfacing to Washington to get it through. Horst Feistel was father of LUCIFER but I understand that he did not have it fully detailed, notably he did not have the innards of the S boxes defined although he did describe their transfer functionality.

I assume this is the Mayer of Matyas and Mayer, the Wiley book on Crypto? Please note that all of these people are, at best, cryptographers. And there is some question about that I suspect. Tuchman is a system designer; is that not also true of Kent? But whatever they are and no matter how good they are as cryptographers and system integrators of cryptographic algorithms and protocols, the bottom line is: are any of them cryptanalysts? It takes a cryptanalyst to think dirty and understand where inherent weaknesses of an algorithm might be, and what attacks against it might work. Unsigned
