Abstract
This document specifies new Camellia cipher suites for the Transport
Layer Security (TLS) protocol to support authentication based on Pre-
Shared Key (PSK). This document realizes compatibility with RFC4297,
RFC5487, and RFC5489 specified in AES cipher suites.

Internet-Draft PSK Camellia Cipher Suites for TLS January 2010
1. Introduction
This document specifies new Camellia cipher suites for the Transport
Layer Security (TLS) protocol to support authentication based on Pre-
Shared Key (PSK). These PSK is symmetric key, shared in advance
among the communicating parties. This document realizes a
compatibility with RFC4297 [3], RFC5487 [5], and RFC5489 [4]
specified in AES cipher suites.
The Camellia algorithm and its properties are described in [2].
1.1. Applicability Statement
The cipher suites defined in this document can be negotiated,
whatever the negotiated TLS version is.
The cipher suites defined in Section 3 and 4 for SHA-256/384 can be
negotiated in TLS version 1.2 or higher.
The applicability statement in RFC4297 [3] applies to this document
as well.
1.2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC2119 [1].

6. Security Considerations
For security considerations of PSK for TLS, this document refers to
Section 7 of RFC4297 [3], Section 4 of RFC5487 [5], and Section 5 of
RFC5489 [4].
At the time of writing this document there are no known weak keys for
Camellia. And no security problem has been found on Camellia (see
[6], [7], and [8]).
