With the information superhighway speeding toward us, how will we protect our secrets? Suppose you use your credit card to order a pizza. How will we keep your neighbor from seeing the number? How will we keep the pizza house from using your credit card for a month's worth of pepperoni? Security, privacy, and encryption are key elements of the emerging cable-based broadband networks.
This paper describes the infrastructure necessary to provide security as part of the underlying infrastructure for broadband networking. It will provide a brief tutorial on the key elements of security, with a focus on the implications in a broadband, cable-based network and participation in a global information network.
