The availability of critical services and systems such as water and power control systems becomes an extraordinary urgent and important issue, as we see more and sophisticated cyber attacks aiming at disrupting these critical services and systems. In this project, we will address this fundamental issue and investigate strong protection schemes for critical communications on the nation’s information infrastructure. We will examine the limitations of the current mechanisms and the main challenges in addressing these problems. As the first step to address these issues, we focus on bandwidth flood attacks and propose a bandwidth reservation framework at the infrastructure level to assure the service quality of critical communications under flood attacks.
The current Internet does not provide hard guarantees for mission
critical communications. Although quality-of-service (QoS) has been extensively
examined in the past decade and many QoS schemes have been proposed, we have
not seen a practical QoS solution broadly deployed on the Internet, espec
To address this issue, we will develop a security framework that
provides infrastructure-level protection for the communications of
mission-critical systems by incorporating secure bandwidth reservation and
management with Trusted-Computing (TC) platforms. We will emphasize the
following research issues: (1) We will examine the limitations of current approaches, and present
a promising practical framework to address these limitations. (2) We
will investigate and design secure highly-available mechanisms and algorithms
to assure the service quality for critical systems, which support provable
guarantees for critical systems against den
