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.

Project need:

To review the Standard within the required 5 year period.
