Application-Assisted Dynamic Attestation for JVM-Based Cloud

In the recent years, cloud computing has expanded rapidly and improved the working efficiency for a number of cloud users, however, a few enterprises hesitate to move to the cloud because of the runtime security challenges of applications although cloud vendors promise to provide a trustworthy execution platform. In this paper, we propose Trusted Cloud Root Broker to give robust trustworthy guarantees to those JVM-Based applications. The broker as the application-root of the trust is to make the evaluation of the runtime trustworthiness and support dynamic attestation about the integrity state of an application with the assistance of Java virtual machine. It could not just prove the authenticity but also offer the availability for these targeting applications. What is more, our broker has less performance overheads.
