P4S -- Processes for Safe and Secure Software and Systems

Welcome to the wiki of the P4S team of Lab-Sticc.


The P4S team is member of the SHARP cluster of the Lab-STICC laboratory (UMR 6285).

Its name is an acronym for Processes for Safe and Secure Software and Systems.

Our interest is in (methods and tools) to (specify and describe) (systems and software) so that (evaluation and analysis) ((increase confidence) and (ensure (safety and security))).

We use:

  • System modeling; because the product needs to be described
  • Process modeling and process improvement; because the development process is a key to safety, security and more generally confidence

We rely on:

  • Models federation; because many points of view need to be merged.
  • Free modeling; because points of views are specific and no framework (meta-model) can catch all points of view.
  • Formal Verification at all stages, all levels: intra-model, inter-models.
  • Mixing automatic and semi-automatic techniques
