I just found out about RCE today. Although I've heard of reverse engineering, I hadn't thought of it as a decryption process before. That made me think: should compilation be like an encryption function or cryptographic hash function, i.e. should it take in code and produce a pseudorandom binary?

It might help protect "trade secrets" (if code can be considered a trade secret).

On the other hand, should it be completely reversable, as a pseudorandom binary would serve no purpose other than obscuring the code (as far as I can tell). It doesn't protect from exploitation (because that would be security through obscurity).

What are your thoughts?

I think that is an interesting idea, but there are a number to technological obstacles that would have to be overcome first:

The main issue is that the code has to be in a format that the CPU (at the lowest level) or OS can understand. Since a hash function is one-way, returning the code to a state that could be executed would not be possible.

Encryption, on the other hand, could be possible. But, for that to work, and to make reverse engineering more difficult, you would need an asymmetric encryption with the private key being either built into the CPU or encoded into the OS. Either of which would certainly make static analysis of the executable more difficult, that is of course until someone discovers the decryption key and leaks it on the internet (remember the DVD and Blue-Ray key leaks?).

I do like the idea though, and I certainly will give it more thought.
