Abstract
An extensible authentication framework is used in cable networks such as Data Over Cable Service Interface Specification (DOCSIS) cable networks. The authentication scheme allows for centralized authentication of cable modems, as well as authentication of the cable network by cable modems. Additionally, the authentication scheme allows a Cable Modem Termination System (CMTS) to authenticate devices downstream from cable modems, such as Customer Premise Equipment (CPE) devices.
