Transitioning Applications to Semantic Web Services: An Automated Formal Approach
Semantic Web Services have been recognized as a promising technology that exhibits huge commercial potential, and attract significant attention from both industry and the research community. Despite expectations being high, the industrial take-up of Semantic Web Service technologies has been slower than expected. One of the main reasons is that many systems have been developed without considering the potential of the web in integrating services and sharing resources. Without a systematic methodology and proper tool support, the migration from legacy systems to Semantic Web Service-based systems can be a very tedious and expensive process, which carries a definite risk of failure. There is an urgent need to provide strategies which allow the migration of legacy systems to Semantic Web Services platforms, and also tools to support such a strategy. In this paper we propose a methodology for transitioning these applications to Semantic Web Services by taking the advantage of rigorous mathematical methods. Our methodology allows users to migrate their applications to Semantic Web Services platform automatically or semi-automatically
SPEEDY: An Eclipse-based IDE for invariant inference
SPEEDY is an Eclipse-based IDE for exploring techniques that assist users in
generating correct specifications, particularly including invariant inference
algorithms and tools. It integrates with several back-end tools that propose
invariants and will incorporate published algorithms for inferring object and
loop invariants. Though the architecture is language-neutral, current SPEEDY
targets C programs. Building and using SPEEDY has confirmed earlier experience
demonstrating the importance of showing and editing specifications in the IDEs
that developers customarily use, automating as much of the production and
checking of specifications as possible, and showing counterexample information
directly in the source code editing environment. As in previous work,
automation of specification checking is provided by back-end SMT solvers.
However, reducing the effort demanded of software developers using formal
methods also requires a GUI design that guides users in writing, reviewing, and
correcting specifications and automates specification inference.Comment: In Proceedings F-IDE 2014, arXiv:1404.578

A Static Verification Framework for Secure Peer-to-Peer Applications
In this paper we present a static verification framework to support the design and verification of secure peer-to-peer applications. The framework supports the specification, modeling, and analysis of security aspects together with the general characteristics of the system, during early stages of the development life-cycle. The approach avoids security issues to be taken into consideration as a separate layer that is added to the system as an afterthought by the use of security protocols. The main functionality supported by the framework are concerned with the modeling of the system together with its security aspects by using an extension of UML, modeling of abuse cases to represent scenarios of attackers and assist with the identification of properties to be verified, specification of properties to be verified in a graphical template language, verification of the models against the properties, and visualization of the results of the verification process
