usually includes questions about the necessity for the new proposal, its security,
possible use cases, how it compares to algorithms in existing standards, etc.
The decision to initiate a new working item as a result of an SP is made by the
experts participating in the following meeting, and approved by NB ballot.
Working Draft (WD)
Once it has been decided to initiate a project, a working draft is circulated among the
experts associated with the Working Group (WG) in charge of the project. The role
of the project editor is to receive, resolve, and integrate comments from the experts
to build consensus. A Working Draft (WD) usually undergoes several revisions until
the experts agree that it is ready to progress to the Committee Stage as a Committee
Draft (CD).
Committee Stage (PDAM, Proposed Draft Amendment)
The committee stage is the principal stage at which comments from NBs are taken
into consideration. Once the Working Group experts agree that a draft proposal
is mature enough to progress to the Committee Stage, a ballot is sent to all NBs
which are requested to vote to approve this draft. While NBs are obliged to vote,
the internal process through which the NBs vote is decided is governed by its own
internal working procedures. When an NB wishes to vote to reject a proposal,
they must also provide justification. Many of the national bodies do not have the
required expertise to evaluate all proposals they receive and they either abstain or
automatically approve proposals, by default.
The goal of the Committee Stage is to reach consensus among the national bodies
involved. The definition of consensus is given in [217] and [295, Sect. 2.5.6]:
Consensus: General agreement, characterized by the absence of sustained opposition to
substantial issues by any important part of the concerned interests and by a process that
involves seeking to take into account the views of all parties concerned and to reconcile any
conflicting arguments.
NOTE: Consensus need not imply unanimity. . . . in case of doubt concerning consensus,
approval by a two-thirds majority . . . may be deemed to be sufficient for the committee draft
to be accepted for registration as an enquiry draft; however, every attempt shall be made to
resolve negative votes.
Further Stages
A consensual proposal that has been approved in the committee stage goes through
more stages until its final publication. Since Simon and Speck, the subjects of this
chapter, did not make it past the committee stage we do not explain the further stages
here, and refer the interested reader to [295, Sec. 2].
