The DDS Security plugin is a standard-based plugin implementation for the DDS middleware that's used to ensure confidentiality and integrity of the data transmitted in the DDS Global Data Space. The information assurance with the DDS Security plugin is realized through three main subservices: authentication, access control, and cryptographic.

I was involved in these activities:
• Development of the cryptographic subservice in which the key generation, key exchange, and data transmission operations are performed.
• Integration of the DDS Security plugin into the DDS middleware core code.
• Refinement of the C++-to-Java mapping (DDS Java API) of the DDS middleware.

During development, I used the OpenSSL library extensively and gained hands-on experience in the cybersecurity domain. During the Java API refinement, I utilized the SWIG tool and gained hands-on experience in Java Native Interface (JNI).

This standard-based implementation exposed access to the DDS Global Data Space via web-friendly protocols and, thus, allowed applications built on various technology stacks to communicate with native DDS applications. It was implemented in Java and supported REST and WebSocket connections.

I was involved in the migration of the legacy, Java EE-based service endpoints of the Web-Enabled DDS to the Vert.x toolkit. With this change, users no longer needed to set up application servers, such as WildFly, to execute the Web-Enabled DDS, and a hardware security module (HSM) configuration for HTTPS connections became more user-friendly.

During this refactor, I gained experience in the Vert.x toolkit, WebSocket protocol, and REST architecture.
