The authenticated datagram protocol: A high performance, subtransport level, secure communication protocol
Advances in communication technologies have stimulated the development of computer networks that interconnect competing individuals, organizations, and even countries. In such computer networks, in order to communicate security, agents must establish secure channels to other agents. In this paper, we present a secure communication protocol called Authenticated Datagram Protocol (ADP) that establishes host-to-host secure channels across networks, and builds agent-to-agent channels on top of host-to-host channels. We show how such a protocol can be layered at the subtransport level of the network protocol hierarchy, so as to provide high performance and security even in the presence of untrustworthy entities on the network.
