“…Li et al [34] studied the reliability-aware synthesis problem for composing available services automatically and guaranteeing that the composed result satisfies the specifications, such as temporal constraints of functionality. The approach focuses on handling attributes and state relations, and permitting users and services to operate over them.…”

This article highlights some recent research advances on trusted computing in China, focusing mainly on the methodologies and technologies related to trusted computing module, trusted computing platform, trusted network connection, trusted storage, and trustworthy software. Trusted computing leads an emerging trend in information technology towards improving the trustworthiness and security of computer systems. It has attracted great worldwide attention from both academia and industry in recent years.In particular, computer scientists in China have devoted considerable effort to this challenge and have made substantial achievements, which enables them to be at the forefront of this area. This article gives a review of some recent research progress in the methodology and technology of trusted computing in China. We summarize the major advancements in this field from two aspects: trusted computing infrastructure and trustworthy software.

It is clear that transactional behavior consistency is a prerequisite and basis for construction of a reliable services-based business application. However, in previous works, maintaining transactional consistency during exception handling was ignored. Maintaining transactional consistency requires functionality for rolling back some operations and revoking uploaded data. Replacing only the failed service will eventually lead to overall business application failure. In this study, we take fully into account the behavioral consistency of transactional services and propose two effective self-healing mechanisms for service-based applications. If a service enters into potential failure condition, a rescheduling mechanism is triggered to maintain consistent transactional behavior and to ensure reliable execution; if a service fails during execution, the compensation operation is triggered and the system will take action to ensure transactional behavior consistency. Meanwhile, cost-benefit analysis with compensation support is proposed to minimize the dynamic reselection cost. Finally, the experimental analysis shows that the proposed strategies can effectively guarantee the reliability of Web-based applications system.
