Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives or www .iec .ch/ members
_experts/ refdocs).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www .iso .org/ patents) or the IEC
list of patent declarations received (see patents.iec.ch).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso .org/

Annex B
(normative)
Conformance and reference software
B.1 General
This annex provides a verification toolset for content sensitive encryption (CSE) as described in
Annex A. It contains the following components:
— Reference software: implementations which demonstrate the CSE method for AVC and HEVC.
— Test vectors: stand-alone compliant content that implements elements of the document.
This software is available at https:// standards .iso .org/ iso -iec/ 23000/ -21/ ed -1/ en/ amd/ 1/
B.2 Content sensitive encryption reference software
B.2.1 Reference software presentation
Unlike previous encryption schemes, content sensitive encryption considers the coding structure of the
video compressed bitstream and encrypts only the most sensitive information in the video bitstream.
Also, CSE generates protected bitstreams that can be d
