Description of Working Group:

  The purpose of the MSEC WG is to standardize protocols for securing
  group communication over internets, and in particular over the global
  Internet. Initial efforts will focus on scalable solutions for groups
  with a single source and a very large number of recipients. Additional
  emphasis will be put on groups where the data is transmitted via
  IP-layer multicast routing protocols (with or without guaranteed
  reliability). The developed standard will assume that each group has a
  single trusted entity (the Group Controller) that sets the security
  policy and controls the group membership. The standard will strive
  to provide at least the following basic security guarantees:

  + Only legitimate group members will have access to current group
  communication. This includes groups with highly dynamic membership.

  + Legitimate group members will be able to authenticate the source
  and contents of the group communication. This includes cases where
  group members do not trust each other.

  An additional goal of the standard will be to protect against
  denial-of-service attacks, whenever possible.

  Due to the large number of one-to-many multicast applications and the
  sometimes conflicting requirements these applications exhibit, it is
  believed that a single protocol will be unable to meet the requirements
  of all applications. Therefore, the WG will first specify a general
  Reference Framework that includes a number of functional building
  blocks. Each such building block will be instantiated by one or more
  protocols that will be interchanable. The Reference Framework will not
  only describe one-to-many multicast, but also many-to-many multicast.

  In addition, as a secondary goal the MSEC WG will also focus on
  distributed architectures for group key management and group policy
  management, where for scalability purposes multiple trusted entities
  (such as Key Distributors) are deployed in a distributed fashion. For
  this purpose, the Reference Framework will not only describe
  one-to-many multicast, but also many-to-many multicast.

  MSEC will generate at least the following documents, which could be
  considered as base documents:

  1. An RFC describing the security requirements of multicast security
  and
  an RFC describing the MSEC Architecture.

  2. An RFC describing the Group Key Management Architecture and an RFC
  describing Group Policy Management Architecture in MSEC.

  3. Several RFCs describing specifications for protocols that implement
  source authentication, group key management and group policy
  management.
  As multicast security covers a broad range of issues, and therefore
  touches other Working Groups in the IETF, the MSEC WG will work closely
  with othersecurity-related Working Groups (e.g. IPsec, IPSP), as well
  as other Working Groups which maybe considered a 'consumer' of the
  technologies produced in the MSEC WG (e.g. AVT, MMUSIC) or which may
  have a multicast focus (e.g. PIM, RMT, IDRM, MAGMA).

  With this in mind, the MSEC WG is open to receiving new work items,
  whenever it is considered appropriate to be homed in the MSEC WG. Such
  drafts will be matured in conjunction with the MSEC base documents.
