product is a Key Distribution Center for:
- PacketCable VoIP deployments that conform to the
PacketCable specifications, and for PacketCable Multimedia deployments
- combined PacketCable/CableHome networks (for MSO-managed in-home networking)
We also have a product, CertBuilder, designed to help to create and check
digital certificates for PacketCable and CableHome networks.
Our PacketCable KDCs include support for
dynamic service keys. Since this functionality is yet to be included in the
PacketCable security specification, here
is an extract from our User Guide that describes how PacketCable-compliant servers can
obtain dynamic service keys from an IPfonix, Inc. KDC.
The KDC throughput necessary to support a large PacketCable deployment (of a million or more MTAs) is often
miscalculated. Here is a paper
that describes what KDC throughput is
actually necessary in deployed PacketCable networks, and here is a Web page
showing the actual CPU load
of an IPfonix, Inc. KDC while running on networks containing more than a million MTAs.
The KDC is almost certainly the least expensive MSO device -- in both software and hardware cost -- in a deployed
PacketCable or CableHome network. We wish to take this opportunity to applaud publicly the PacketCable security team for
designing a security architecture that permits MSOs to deploy highly-secure systems that allow single sign-on to multiple services at miniscule per-subscriber incremental
