A new Internet Draft defining the SILC Key Exchange and Authentication Protocols is available, and has been submitted to the IETF. o SILC Key Exchange and Authentication Protocols http://silcnet.org/docs/draft-riikonen-silc-ke-auth-05.txt 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). Changes to previous draft: o Defined that the security property strings in the Key Exchange Start Payload SHOULD be UTF-8 encoded. o Defined that the passphrase sent in Connection Authentication protocol MUST be UTF-8 encoded.
