Abstract:
Based on extensions to the protocols PPP and IPSEC, we present a working proposal for building a network over which messages can be sent unconditionally secure. We will show how quantum cryptography can be implemented in classical protocols and how existing networks can be efficiently extended to suit our needs for unconditional security. We show that graph connectivity is crucial for the security of the transmission. For that matter, we provide secure routing services, so an adversary cannot penetrate any message flow successfully. Furthermore, our protocols are extensible to allow up to t − 1 adversaries (possibly cooperating) while remaining unconditionally secure.
