DDS Security a family of security mechanisms defined for the Data Distribution Service middleware ecosystem.

Technology context

Data Distribution Service (DDS) supports data-centric publish-subscribe communication. DDS Security specifies interfaces and mechanisms for participant authentication, access control and cryptographic protection.

Specification evolution

The Object Management Group lists DDS Security version 1.2 as a formal version adopted in February 2026. Actual support depends on the DDS implementation and its enabled plugins and configuration.

Deployment considerations

Policies must define which participants may publish or subscribe to particular topics. Security credential handling, certificate expiry and failures during discovery affect operations.

Limits

DDS Security can protect middleware communication but cannot establish correctness of all application data, control logic or physical movement. Real-time deadlines and availability remain separate design concerns.
