Wondered what the state of the art is on keeping embedded code secret. Who does it better these days?
I see some secure processors from Atmel and a few others, but they seem more oriented to securing comms and data than in securing their own code.

If these guys do this just for fun, I suppose there must be low-profile companies who will pull the code off of any chip for $$$, no questions asked.
So the best security is to design things no one wants to duplicate.
ARM TrustZone provides a convenient way for authenticating code, but for confidentiality you need also some secure storage. There should be some ARM chips like that out there.
