Research on Endpoint Isolation and Remediation Mechanism Based on Trusted Access Technology

Abstract

Trusted Computing Technology provides powerful support for the solution to security issues of embedded endpoints in network computing environment. In this paper a general framework of trusted access, which is for implementation on embedded trusted endpoints, is presented. The paper describes the authentication procedure of trusted access and its formal definition, and the design and implementation of the trusted access protocol. Finally, the paper presents an isolation and remediation mechanism based on embedded trusted access. The mechanism is based on 802.1X, VLAN and TNC, and can be used on both wire and wireless embedded endpoints.
