RFC 4581               CGA Extension Field Format           October 2006
1.  Introduction
   The Cryptographically Generated Address (CGA) specification [1]
   defines Extension Fields that allow additional information to be
   included in the CGA Parameter Data Structure.  So far there seems to
   be enough interest in including additional data items into the CGA
   Parameter Data Structure through these Extension Fields that it seems
   reasonable to expect that more than one mechanism will require its
   usage.  In order to simplify the addition of multiple data items,
   this document updates RFC 3972 [1], and it defines a Type-Length-
   Value format for the Extension Fields.
2.  CGA Extension Field Format
   Data items to be included in Extension Fields of the CGA Parameter
   Data Structure MUST be encoded using the following Type-Length-Value
   (TLV) format:
    0                   1                   2                   3
    0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
   |                                                               |
   ~                       Extension Data                          ~
   |                                                               |
   +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
   Extension Type: 16-bit identifier of the type of the Extension Field.
   Extension Data Length: 16-bit unsigned integer.  Length of the
   Extension Data field of this option, in octets.
   Extension Data: Variable-length field.  Extension-Type-specific data.
3.  IANA Considerations
   The IANA has created and will maintain a registry entitled, "CGA
   Extension Type".  The values in this name space are 16-bit unsigned
   integers.  Initial values for the CGA Extension Type field are given
   below; future assignments are to be made through Standards Action
   [2].  Assignments consist of a name and the value.
   As recommended in [3], this document makes the following assignments
   for experimental and testing use: the value 0xFFFD, with name
   Exp_FFFD; the value 0xFFFE, with name Exp_FFFE, and the value 0xFFFF,
   with name Exp_FFFF.

4.  Security Considerations
   No security concerns are raised by the adoption of the CGA Extension
   format described in this document.  However, proper security analysis
   is required when new CGA Extensions are defined in order to make sure
   that they introduce no new vulnerabilities to the existing CGA
   schemes.
