I just came up with an idea that can resist rubber hose cryptanalysis: Quantum physics. Take a password, use some key stretching. Interpret the result: 0 indicates measure up-down. 1 indicates measure left-right. Measure qubits using this pattern. Get harddrive encryption key. If as a prisoner you lie to your captors and they fall for it, they will measure the wrong way and the harddrive key is destroyed forever. They way qubits work you only get one attempt.
