The most secure computer is the one locked in a room and unplugged.
There has never been a method of security that is secure. The first thing you learn when dealing with security is there are tradeoffs between opportunity, time, money. and usability.
- aroman 13y agoWhile I agree with the spirit of your post, there is in fact a method of security that is definitively unbreakable (if used correctly/precluding side-channelling): the one-time-pad. But as you imply, the reason we don't use it is because the opportunity cost and hassle of using it are too high for many uses.
