comment Is there a protocol for securely trading information between possibly uncooperating agents?
I think I've understood it, and I agree with you that it's impossible to make it completely secure. However, there are a lot of problems which don't have an optimal solution, but suboptimal solutions are still used. A standard bicycle lock is no burden at all against a very skilled thief, but it's still being used, not to deter the world's best bicycle thief, but to deter most random passers-by. I was hoping such a service exists, which doesn't guarantee 100% security but can be useful for cases where the information is not that important that people will go out of their way to hack the system

comment Is there a protocol for securely trading information between possibly uncooperating agents?
The links are very interesting, but they are also very theoretical. If I had to implement a system which automatically does this, I could do it without any problems. What I'm searching for is an already existing, practical implementation, this is why I asked the question here and not at crypto.

comment How can I protect my internet-connected devices from discovery by Shodan?
If we're at it, we could also add some System Shock references. Now I can't take "L-L-L-Look at you, h-h-hacker..." out of my mind.

comment How is an ATM secure?
It does not violate any principles. Physical access in case of a PC means that you can easily boot your own operating system and run your own programs with full rights, because the PC has the interface for it (CD drive, USB port, etc.)

comment Why are vulnerabilities and lack of security possible in computers?
wait, how could Neumann be Dutch? I thought he was Hungarian who later emigrated to the USA.

comment How do you log in from an unsecured computer?
If the login is not something crucial (e.g. bank login which you should not do at all from an unsecured computer), and I suspect a keylogger, I usually enter my password in the wrong character order, aided by the mouse. Not a perfect solution, but might throw off most of the beginner kiddies.

comment Is there a reason to protect SIM with PIN?
This is only valid if a phone is lost or stolen while switched off. I usually have entire months or even years when I don't have to enter the PIN because my phone is never turned off. I think most people don't carry phones around while they are switched off or have empty batteries.
