SILC - Secure Internet Live Conferencing
To: All who are uneasy about using insecure IM/IRC technologies.
I first heard about SILC about 8 months or so ago and have, from time to time, checked up on it, to see how much progress the project has made.
SILC is an IRC type program. Here is an excerpt from the site:
------------
SILC (Secure Internet Live Conferencing) is a protocol which provides secure conferencing services on the Internet over insecure channel. SILC superficially resembles IRC, although they are very different internally. They both provide conferencing services and have almost the same set of commands. Other than that, they are nothing alike. The SILC is secure and the network model is entirely different compared to IRC.
SILC provides security services that any other conferencing protocol does not offer today. The most popular conferencing service, IRC, is entirely insecure. If you need secure place to talk to some person or to group of people over the Internet, IRC or any other conferencing service, for that matter, cannot be used. Anyone can see the messages and their contents in the IRC network. And the most worse case, some is able to change the contents of the messages. Also, all the authentication data, such as, passwords are sent plaintext in IRC.
SILC is much more than just about `encrypting the traffic'. That is easy enough to do with IRC and SSL hybrids, but even then the entire network cannot be secured, only part of it. SILC provides security services, such as sending private messages entirely secure; no one can see the message except you and the real receiver of the message. SILC also provides same functionality for channels; no one except those clients joined to the channel may see the messages destined to the channel. Communication between client and server is also secured with session keys and all commands, authentication data (such as passwords etc.) and other traffic is entirely secured. The entire network, and all parts of it, is secured. We are not aware of any other conferencing protocol providing same features at the present time.
SILC has secure key exchange protocol that is used to create the session keys for each connection. SILC also provides strong authentication based on either passwords or public key authentication. All authentication data is always encrypted in the SILC network. Each connection has their own session keys, all channels have channel specific keys, and all private messages can be secured with private message specific keys.

I am not sure if people will pick this up or not. I suppose it really depends, on how many people hear about it, who want secure communication IRC Style.
