Description	This document describes architecture of communication node suitable for storage of unconditionally secure cryptographic key. It also describes cryptographic protocols providing unconditionally secure synchronization of two key buffers while the key is fluently delivered by a trusted device in an asynchronous way. This system will be used in the SECOQC QBB node to implement unconditionally secure communication in a VPN on internet.
