This repository contains the formal model and proofs for SOAP, a Social Authentication protocol. The models were encoded for the Tamarin model checker, version 1.8.0.
As the model (signal-oidc.spthy) is very large and proofs take a considerable time (in the range of hours), the directory /proofs contains the finished proofs for every lemma in the theory.
The README in that directory describes which proof-file contains proofs for which lemma.
To check the proofs, first install Tamarin.
Afterwards, you can navigate to either the root folder or /proofs and run Tamarin in interactive mode:
tamarin-prover interactive .
If you want to inspect the model for privacy, you must additionally provide the --diff argument to Tamarin.
Tamarin should then run on localhost:3001.
If you navigate to that page, you should see a table showing one entry for every *.spthy file in the folder.
Loading one of these files will also load the proofs.
You can see that a lemma was proven if it is highlighted in green.
