Title : SILC Key Exchange and Authentication Protocols
Author(s) : P. Riikonen
Filename : draft-riikonen-silc-ke-auth-08.txt
Pages : 23

This memo describes two protocols used in the Secure Internet Live
Conferencing (SILC) protocol, specified in the Secure Internet Live
Conferencing, Protocol Specification [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 use best parts
of the SSH2 Key Exchange protocol, Station-To-Station (STS) protocol
and the OAKLEY Key Determination protocol [OAKLEY].
The second protocol, 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)
based on digital signatures.

In the body type:
"FILE /internet-drafts/draft-riikonen-silc-ke-auth-08.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
