Bachelor thesis Tim Pollandt 2020

How to Run

  1. Install Maven and verify it is installed (mvn --version).
  2. Run mvn clean package.
  3. The JAR file is placed in target/.
  4. Run the experiments using java -jar bachelors-thesis.jar <Experiment> <DebugOutput> <MinSize> <MaxSize> <StepSize> <Runs>.
  • Experiment: Can be Auctioneer or Needham. More possibilities could be added in future releases.
  • DebugOutput: Boolean. Is always true for Auctioneer example. If true, for each translation step the current terms are printed in files. Choose false for time measures.
  • MinSize: Integer > 1. Only has an effect for Needham example. Chooses initial number of communicating pairs.
  • MaxSize: Integer >= MinSize. Only has an effect if Experiment=Needham and DebugOutput=false. Specifies the last number of communicating pairs for a loop (for time measures). Big numbers can lead to a massive memory consumption.
  • StepSize: Integer > 0. Only has an effect if Experiment=Needham and DebugOutput=false. Specifies the step size for the loop over number if pairs of communicating partners.
  • Runs: Integer > 0. Only has an effect if Experiment=Needham and DebugOutput=false. Attempts per number of communication pairs for time measures.

run.sh provides en example execution as used in our experiments.

Experiments

The experiment data is in the experiments folder. Our experiments used the Needham experiment for n=1..600 with 15 attempts. With experiments.py the approximation functions can be determined from measured data.

Bachelor thesis on G/Pi -> SGP -> Promela

Main parts (see thesis for more details):

  • AST Modelling
    • Pi calculus
    • Global types
    • SGP
  • Converter
    • P/G to SGP
    • SGP to Promela
  • Tests
    • Scalable Needham-Schroeder in G/P
    • Speed tests

This is part of a Bachelor thesis at TU Darmstadt. Pi calculus terms with concurrency are translated to one sequential term following the global type's structure. Afterwards this is translated to Promela code.
