The Data Distribution Service (DDS) standard is getting significant updates with its latest release, version 1.2. 

DDS is a data connectivity standard that enables developers to provide real-time data to IoT systems. 

The new version contains a more robust security model, including:

  • NSA approved algorithms
  • Pre-shared keys to better protect from DoS attacks
  • Key revisions that support certificate revocation, expiration, and access rights changes
  • Improved ways to manage permissions for large systems

“As systems become more interconnected and intelligent, protecting data against cyberattacks and unauthorized participants becomes increasingly challenging. The first step to securing a distributed system is to protect its data,” said Gerardo Pardo, co-chair of the DDS Special Interest Group (OMG) and CTO at Real-Time Innovations (RTI). “The latest version of the DDS Security spec integrates modern best practices to protect systems. As a publish/subscribe protocol, DDS helps ensure that only authorized users and nodes can transmit and receive data, providing zero-trust, end-to-end data protection, and data origin authentication.

DDS 1.2 can be downloaded here from the Object Management Group’s website.
