This paper presents a Bulk-Synchronous Parallel (BSP) algorithm to compute the discrete state space of structured models of security protocols. The BSP model of parallelism avoids concurrency related problems (mainly deadlocks and non-determinism) and allows us to design an efficient algorithm that is at the same time simple to express. A prototype… (More)

As any software, model-checkers are subject to bugs. They can thus report false negatives or validate a model that they should not. Different methods, such as theorem provers or Proof-Carrying Code, have been used to gain more confidence in the results of model-checkers. In this paper, we focus on using a verification condition generator that takes… (More)

—This paper presents a Bulk-Synchronous Parallel (BSP) algorithm to compute on-the-fly whether a structured model of a security protocol satisfies a LTL formula. Using the structured nature of the security protocols allows us to design a simple and efficient parallelisation of an algorithm which constructs the state-space under consideration in a… (More)

This paper presents a distributed (Bulk-Synchronous Parallel or bsp) algorithm to compute on-the-fly whether a structured model of a security protocol satisfies a ctl $$^*$$ ∗ formula. Using the structured nature of the security protocols allows us to design a simple method to distribute the state space under consideration in a need-driven fashion. Based on… (More)

This paper presents the implementation and the performance comparisons of two Bulk-Synchronous Parallel (BSP) algorithms to compute the discrete state space of models. These algorithms are simple to express and the first one is the most general one whereas the second is dedicated for structured models of security protocols. Benchmarks of security protocol… (More)
