Doing encryption well in an embedded system is not hard. It's just a case of choosing the right approach for the CPU/memory requirements you have. And he's got a hardware accelerator! Sheesh!
There is a certain amount of that sort of attitude among embedded system programmers I have known - very much a "I have to code in less space and less cycles than you, therefore dont try to question how I do things".
Theres very much a "it's not possible to do X in an embedded system" attitude floating around, which usually turns out to be false. I had the same argument about writing object-oriented code for embedded systems. Everyone said "you cant do that. It doesnt work in embedded systems. It'll be too slow". Turns out the answer is.. "Not if you do it right".
