We propose a formal semantics for distributed transactions inspired by the attribute mechanisms of the Java Transaction API. Technically, we model services in a process calculus fe...
A central theme of the semantic web is that programs should be able to easily aggregate data from different sources. Unfortunately, even if two sites provide their data using the ...
In [5] we build a formal verification technique for game based correctness proofs of cryptograhic algorithms based on a probabilistic Hoare style logic [10]. An important step towa...
The increasing number of infrastructure services requires the existence of mechanisms to discover and select services and resources, called service broker, based on customer requir...
Compensation is an error recovery mechanism for long-running transactions. Compensating CSP is a variant of the CSP process algebra with constructs for orchestration of compensatio...
