We propose a new paradigm for security of quantum protocols. Instead of making one, powerful, difficult to check assumption about the system, we make a few, which are easy to verify or otherwise justify. This enables us to combine very high security levels with relatively low hardware complexity. We present a self-testing quantum random number generator that demonstrates the usefulness of our paradigm. We describe this device, prove its security against active attacks, backdoors and malfunctions and analyze its efficiency.
