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/

iso/ foreword .html. In the IEC, see www .iec .ch/ understanding -standards.

This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,

Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.

A list of all parts in the ISO/IEC 23000 series can be found on the ISO and IEC websites.

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
