Information security — Lightweight cryptography — Part 7: Broadcast authentication protocols
This document specifies broadcast authentication protocols, which are protocols that provide data integrity and entity authentication in a broadcast setting, i.e. a setting with one sender transmitting messages to many receivers. To provide entity authentication, there needs to be a pre-existing infrastructure which links the sender to a cryptographic secret. The establishment of such an infrastructure is beyond the scope of this document.

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).
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
Many IT environments involve broadcast communication, in which one sender communicates with
multiple receivers. Securing such communication is a non-trivial task. Broadcast authentication
protocols aim to enable the recipient to verify the authenticity of transmitted data and ensure entity
authentication of the sender.
A straightforward way of achieving broadcast authentication is to use digital signatures, as for example
described in the ISO/IEC 9796 series or ISO/IEC 14888 series. However, there are situations in which
the additional communication and computational overhead of digital signatures are prohibitively
expensive, as can be the case with satellites broadcasting to earth.
This document specifies lightweight broadcast authentication protocols, which offer a significantly
lower implementation cost than deploying digitial signatures as a solution to the authentication of
broadcast communication.

1 Scope
This document specifies broadcast authentication protocols, which are protocols that provide data
integrity and entity authentication in a broadcast setting, i.e. a setting with one sender transmitting
messages to many receivers. To provide entity authentication, there needs to be a pre-existing
infrastructure which links the sender to a cryptographic secret. The establishment of such an
infrastructure is beyond the scope of this document.
