Description of Working Group
The dhc working group (DHC WG) has developed DHCP for automated
allocation, configuration and management of IP addresses and TCP/IP
protocol stack parameters. DHCP is currently a "Draft Standard". The
base protocol is documented in RFC2131 and RFC2132 (DHCP for IPv4) and
RFCxxxx (DHCP for IPv6). Additional options are documented in
subsequent RFCs.
The DHC WG is responsible for reviewing (and sometimes developing)
DHCP options or other extensions (for both IPv4 and IPv6). The DHC WG
is expected to review all proposed extensions to DHCP to ensure that
they are consistent with the DHCP specification and other option
formats, that they do not duplicate existing mechanisms, etc. The DHC
WG will not (generally) be responsible for evaluating the semantic
content of proposed options. The DHC WG will not adopt new proposals
for extensions to DHCP as working group documents without first
coordinating with other relevant working groups and determining who
has the responsibility for reviewing the semantic content of an
option.
The DHC WG has the following main objectives:
* The DHC WG will address security in DHCP
o Develop and document security requirements for DHCP. RFC 3118
defines current security mechanisms for DHCPv4. Unfortunately,
RFC 3118 has neither been implemented nor deployed to date.
Specific issues to be considered include:
- Improved key management and scalability
- Security for messages passed between relay agents and servers
- Threats of DoS attacks through FORCERENEW
- The increased usage of DHC on unsecured (e.g., wireless) and
public LANs
- The need for clients to be able to authenticate servers, without
simultaneously requiring client authentication by the server.
o Develop and document a roadmap of any new documents or protocols
needed to meet the security requirements for DHCP
* Write an analysis of the DHCP specification, including RFC2131,
RFC2132 and other RFCs defining additional options, which identifies
ambiguities, contradictory specifications and other obstacles to
development of interoperable implementations. Recommend a process
for resolving identified problems and incorporating the resolutions
into the DHCP specification.
* Complete or abandon work on DHCPv6 options that are currently work
in progress:
