SILC (Secure Internet Live Conferencing) is a protocol which provides secure conferencing services in the Internet. It can be used to send any kind of messages, in addition to normal text messages.
This includes multimedia messages like images, video, and audio stream.
All messages in the SILC network are encrypted and authenticated, and messages can also be digitally signed. SILC protocol supports AES, SHA-1, PKCS#1, PKCS#3, X.509, OpenPGP, and is being developed in the IETF.
The software is delivered as SILC Client for end users, SILC Server for system administrators, and SILC Toolkit for application developers.
Enhancements:
- This version fixes several crash bugs and other minor bugs.

SeSAm (Shell for Simulated Agent Systems) provides a generic environment for modelling and experimenting with agent-based simulation.
We specially focused on providing a tool for the easy construction of complex models, which include dynamic interdependecies or emergent behaviour.
SeSAm agents consist of a body, that contains a set of state variables and a behaviour that is implemented in form of UML-like diagram. Based on an extensive number of primitive components, a user is able to design a simulation graphically without knowing the syntax of a traditional programming language.
The model specification is executable in the same environment and the dynamics of this simulation may be observed. As there are freely configurable instruments for gathering data and scripting options for constructing simulation experiments, SeSAm is a highly valuable tool for MAS simulations especially for complex models with flexible agent behaviour and interactions.
Main features:
- Easy visual agent modelling,
- Flexible environment and situation definition,
- The whole power of a programming language,
- Integrated graphical simulation analysis ,
- Distribution of simulation runs in your LAN ,
- and many further features.....
