1   Scope

This part of ISO/IEC 18033 specifies
  1. a) output functions to combine a keystream with plaintext,
  2. b) keystream generators for producing keystream, and
  3. c) object identifiers assigned to dedicated keystream generators in accordance with ISO/IEC 9834.

NOTE 1 The list of assigned object identifiers is given in Annex A.

NOTE 2 Any change to the specification of these algorithms resulting in a change of functional behaviour will result in a change of the object identifier assigned to the algorithms concerned.
