Introduced a new event:
match(pattern,groundterm)
This event can only be executed if pattern can be matched to groundterm.
Variable substitutions are persistent with respect to later events in
the same role.
Currently implemented as syntactic sugar, essentially unfolded in role R to:
fresh x;
send ( R,R, { groundterm }x );
recv ( R,R, { pattern }x );
This work is not complete yet in the send that the output still contains
the unfolding. Ideally, the graph rendered detects this syntactic sugar
and renders a simplified event. This should be possible on the basis of
the label name prefix.

The Scyther tool repository
This README describes the organization of the repository of the Scyther tool for security protocol analysis. Its intended audience are interested users and future developers of the Scyther tool, as well as protocol modelers. For installation and usage instructions of the Scyther tool see: http://people.inf.ethz.ch/cremersc/scyther/index.html.
Developing
We use Linux during the development of Scyther, but development on Windows and MAC OS X should be equally feasible. Note that the below instructions are written from a Linux/Ubuntu perspective, and probably need modifications for other platforms.
Scyther is written partly in Python (for the GUI, using wxPython) and partly in C (for the backend).
In order to run the tool from a repository checkout, it is required to
compile the C sources into a working binary for the backend. The
simplest way to achieve this is to run the build.sh script in the
./src directory. This script compiles a binary version of the tool on
the native platform. Thus, in the Linux case, it should produce
./src/scyther-linux. This file is automatically copied to the related
directory under ./gui, and if successful you can attempt to run
./gui/scyther-gui.py to use the graphical user interface.
The build process depends on the following (Debian/Ubuntu) packages:
cmakebuild-essentialflexbison
If you are using Ubuntu, installing these may be as simple as running
sudo apt-get install cmake build-essential flex bison
In case you also want to be able to compile Windows binaries from Linux, you also need:
mingw32
Note that welcome all contributions, e.g., further protocol models. Just send us a pull request.
Manual
We are currently rewriting the manual. Bear with us for a second and have a look at the example protocol models.
Protocol Models
The protocol models have the extension .spdl and can be found in the following directories:
./gui/Protocols, containing the officially released models, and./testing, containing models currently under development.
License
Currently these Scyther sources are licensed under the GPL 2, as indicated in the source code. Contact Cas Cremers if you have any questions.
