    "abstract": "A simple proof of the unconditional security of a relativistic quantum\ncryptosystem based on orthogonal states is proposed. Restrictions imposed by\nspecial relativity allow to substantially simplify the proof compared with the\nnon-relativistic cryptosystems involving non-orthogonal states. Important for\nthe proposed protocol is the spatio-temporal structure of the quantum states\nwhich is actually ignored in the non-relativistic protocols employing only the\nstructure of the state space of the information carriers. As a consequence, the\nsimplification arises because of the inefficiency of collective measurements\nwhich constitute the major problem in the non-relativistic case.",
