Final Charter for Working Group

TLS Working Group D. McGrew Internet-Draft Cisco Systems Intended status: Informational D. Bailey Expires: August 5, 2013 RSA/EMC M. Campagna R. Dugal Certicom Corp. February 1, 2013 AES-CCM ECC Cipher Suites for TLS draft-mcgrew-tls-aes-ccm-ecc-06 Abstract This memo describes the use of the Advanced Encryption Standard (AES) in the Counter and CBC-MAC Mode (CCM) of operation within Transport Layer Security (TLS) to provide confidentiality and data origin authentication. The AES-CCM algorithm is amenable to compact implementations, making it suitable for constrained environments. The ciphersuites defined in this document use Elliptic Curve Cryptography (ECC), and are advantageous in networks with limited bandwidth. Status of this Memo This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF). Note that other groups may also distribute working documents as Internet-Drafts. The list of current Internet- Drafts is at http://datatracker.ietf.org/drafts/current/. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress." This Internet-Draft will expire on August 5, 2013.

This WG will study the requirements for "home networking". Home
networks can include (but are not limited to) environments where
neither DNS servers nor DHCP servers are present. The WG will also
survey existing protocols that address the problem of autoconfiguration,
with the aim of understanding whether existing IP protocols are adequate
to solve the needs for autoconfiguration in the "home" environment, or
whether additional protocols are needed.

This WG will produce two informational documents. The first describes
the requirements for the configuration information and services a node
needs in order to fully participate on home networks and/or the
Internet at large. The second details a 'profile' specifying which
protocols specifically satisfy the requirements outlined in the first
document. If it is determined that no existing standard protocol
fulfills the requirements, or that existing protocols are insufficient
or inadequate, the profile may specify that a new protocol is required
or recommend a change to an existing standard to apply to the NITS
environment.

This WG will not develop new protocols. In the event that protocol
work is deemed necessary, a followup WG will be chartered.
