scyther-proof is a security protocol verification tool
based on an algorithm similar to the Scyther tool developed
by Cas Cremers
(http://people.inf.ethz.ch/cremersc/scyther/index.html).
The theory underlying scyther-proof is described in the
2013 Journal of Computer Security paper
"Efficient Construction of
Machine-Checked Protocol Security Proofs"
by Meier, Cremers, and Basin available from
https://github.com/meiersi/scyther-proof/tree/master/publications.
