Scyther is an open source Python tool for proving and verifying security protocols. It offers the possibility to integrate adversaries to compromise protocols and to visualise the result associated with the corruption of these protocols. It has also been used to analyse the IKEv1 and IKEv2 protocols  used in VPNs and various authentication protocols . In this workshop we will learn how to use the tool and prove some protocols.
