Perhaps it could have pointer arithmetic instructions, where "ptr + n" makes code that uses special instructions to decrypt "ptr", add "n", and encrypt the result before giving it back to you?
- anonymousiam 6y agoI don't see how that works. If such an instruction exists, why couldn't an exploit developer use it to defeat pointer encryption?
- dejj 6y agoHomomorphic encryption does that, yes. But in the interview, he talks about it hypothetically.
