1 Scope
This part of ISO/IEC 18033 specifies
a) output functions to combine a keystream with plaintext ,
b) keystream generators for producing keystream, and
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.
