Title:
|
NIST Special Publication 800-38B. Recommendation for Block Cipher Modes of Operation: The CMAC Mode for Authentication. Morris Dworkin. May 2005

|
Justification for the specific reference:
|
|
|
In specification of the procedures for secure key derivation and for management flow (PLOAM and OMCI) integrity verification, Recommendation G.xgs-pon establishes the underlying block cipher, AES, operating in the block cipher-based Message Authentication Code (CMAC) mode. NIST Special Publication 800-38B provides an authoritative specification of the CMAC algorithm. It has been used previously in G.987.3 and G.989.3.

Other useful information describing the "Quality" of the document:
|
|
|
This NIST document has been produced by Computer Security Division's (CSD) Security Technology Group of NIST has a subgroup that deals specifically with Cryptographic Technology Standards and Guidance (CTSG). CTSG is involved in the development, maintenance, and promotion of a number of standards and guidance that cover a wide range of cryptographic technology.
NIST has long term technical experience in dealing with cryptographic matters. The document has been publicly and internally reviewed before publication.

|
Relationship with other existing or emerging documents:
|
|
|
NIST is actively involved in standardization of cryptographic techniques. The crypto tools are of wide general applicability (see e.g. DES, AES, modes of operation and guidelines). NIST continues its research and standardization in the area of modes of operation. NIST continues to accept modes proposals.
