Are there any security measures that are resistant to a brute force attack? -

I'm not talking specifically about encryption, but security as a whole. Is there any security measure that can be used to protect the data and / or a system which can face an imaginary amount of resources against it on the imaginary amount of time?

I do not seem to answer, but I thought I would double check with people before saying this because I am not a security expert.

UPDATE: I should say, I am not saying this because I need it to apply something. This is worthless curiosity. I should also mention that I am fine with fictional here. If there is any relevance then feel free to bring things like quantum computing into the equation

Once pad is such an encryption technique: it is basically safe In other words, against animals, information-theoretically protected if you do not have a key, then you can do it Can calculate on the basis, despite this it can not be "broken". The trick is that it is impossible to distinguish the correct answer from all possible answers , because each answer is equally possible. Unfortunately, once the pad is almost in vain behavior, because the key should be as long as your plain text, the key can not be used again. Is it, and it should be random. This means that you can not get the key with a memorable password, so you need a secure storage method for the key. But if you can already secure a huge key, you can also put your signature without encryption.
