VerifHub

VerifHub allows Verifpal® users to easily share and discuss Verifpal models of cryptographic protocols. The VerifHub service provides unique URIs for each shared model which includes a syntax-highlighted model, an automatically generated diagram and a summary of the analysis results.

Analysis Results

The model submitter provided the following analysis results:

Query 1 (Authentication): FAIL
Query 2 (Authentication): PASS

Please note that these results are not verified to be accurate. The model submitter may choose to provide false analysis results if they so desire. It is strongly recommended that you re-run the analysis of this model locally if you wish to verify the authenticity of the analysis results above.
