SILC Documentation

Currently working on the SILC documentation is in progress and the software does not have extensive documentation at all.

SILC Protocol Internet Drafts

SILC Protocol is documented and four Internet Drafts exist. These Internet Drafts are also available from IETF.
Updated on Sun Jul 22 22:01:38 EEST 2001: These new updated drafts will be submitted to the IETF after the August 14th 2001.

Secure Internet Live Conferencing (SILC), Protocol Specification

Abstract

This memo describes a Secure Internet Live Conferencing (SILC) protocol which provides secure conferencing services over insecure network channel. SILC is IRC [IRC] like protocol, however, it is not equivalent to IRC and does not support IRC. Strong cryptographic methods are used to protect SILC packets inside the SILC network. Three other Internet Drafts relates very closely to this memo; SILC Packet Protocol [SILC2], SILC Key Exchange and Authentication Protocols [SILC3] and SILC Commands [SILC4].

SILC Packet Protocol

Abstract

This memo describes a Packet Protocol used in the Secure Internet Live Conferencing (SILC) protocol, specified in the Secure Internet Live Conferencing, Protocol Specification Internet Draft [SILC1]. This protocol describes the packet types and packet payloads which defines the contents of the packets. It provides secure binary packet protocol that assures that the content of the packets is secured and authenticated.

SILC Key Exchange and Authentication Protocols

Abstract

This memo describes two protocols used in the Secure Internet Live Conferencing (SILC) protocol, specified in the Secure Internet Live Conferencing, Protocol Specification internet-draft [SILC1]. The SILC Key Exchange (SKE) protocol provides secure key exchange between two parties resulting into shared secret key material. The protocol is based on Diffie-Hellman key exchange algorithm and its functionality is derived from several key exchange protocols. SKE uses best parts of the SSH2 Key Exchange protocol, Station-To-Station (STS) protocol and the OAKLEY Key Determination protocol [OAKLEY].

The SILC Connection Authentication protocol provides user level authentication used when creating connections in SILC network. The protocol is transparent to the authentication data which means that it can be used to authenticate the user with, for example, passphrase (pre-shared-secret) or public key (and certificate).

SILC Commands

Abstract

This memo describes the commands used in the Secure Internet Live Conferencing (SILC) protocol, specified in the Secure Internet Live Conferencing, Protocol Specification Internet Draft [SILC1]. The SILC Commands are very important part of the SILC protocol. Usually the commands are used by SILC clients to manage the SILC session, but also SILC servers may use the commands. This memo specifies detailed command messages and command reply messages.
