Free registration required

Executive Summary

In grid and cloud computing infrastructures, the integrity of a computing platform is a critical security requirement in order to provide secure and honest computing environments to service providers and resource consumers. However, due to the fact that software components running on a single platform are usually provided and maintained by different authorities who are potentially untrusted to each other, the problem to monitor and protect run-time system integrity become very challenging and has not been well addressed yet. In this paper, the authors present a virtualization based dynamic integrity protection method which ensures that only appropriate authorities can control over their components without interfering with other component providers or authorities.
