What is ISO/IEC 29192-7 - Broadcast authentication protocols about?
ISO/IEC 29192-7 focuses on Lightweight cryptography. ISO/IEC 29192-7 is the seventh part of the ISO/IEC 29192 series of standards that 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 that links the sender to a cryptographic secret. The establishment of such an infrastructure is beyond the scope of ISO/IEC 29192-7.
Who is ISO/IEC 29192-7- Broadcast authentication protocols for?
ISO/IEC 29192-7 on broadcast authentication protocols is useful for:
- Software developer
- Software engineer
Why should you use ISO/IEC 29192-7 - Broadcast authentication protocols?
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. 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. ISO/IEC 29192-7 specifies lightweight broadcast authentication protocols, which offer a significantly lower implementation cost than deploying digital signatures as a solution to the authentication of broadcast communication.
