What you ask for is not possible, the computer is not yours and the administrator of that computer can do pretty much anything he likes, if they have a keylogger/malware installed then bad luck.

You can only aspire to minimize the risks but you will never be 100% safe, it is not your computer.

I would consider Ironkey if you can afford it. Alternatively look at what kind of software Ironkey has installed and search for free portable software that will do the same thing then install it on your USB, that exists but needs some research to find it.
