Cas Cremers f9a34f4de5 BUGFIX: Updating hashfunction usage in protocol files to new conventions. 
After the new function implementation, the 'Function' type is no longer one-way by default.
However, many protocol description files relied on this implicit assumption.
The solution is to use 'hashfunction' declarations instead to model one-wayness.

Original bug report by Binh Thanh Nguyen.

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://www.cs.ox.ac.uk/people/cas.cremers/scyther/index.html.

Installing from source

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:

  • cmake
  • build-essential
  • flex
  • bison

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. The current (incomplete) snapshot of the manual can be found in the following location:

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.

Currently these Scyther sources are licensed under the GPL 2, as indicated in the source code. Contact Cas Cremers if you have any questions.
