NIST researcher Dr. Eugene Song and Prof. Hiroaki Nishi (Keio University, Japan) presented a research paper titled “Security for IEEE P1451.1.6-based Sensor Networks for IoT Applications” at the 2024 IEEE IECON conference. Their presentation received a best presentation award for its session.
In the presentation, Dr. Song highlighted that the main challenges for Internet of Things (IoT) sensor networks are the lack of robust standards, diverse wireline and wireless connectivity, interoperability between different devices, security, and privacy. IEEE 1451 is a family of standards for smart sensors that addresses these challenges by defining common network services, transducer services, and transducer electronic data sheets (TEDS), with the P1451.1.6 standard focused on IoT devices that communicate using the MQTT (Message Queuing Telemetry Transport) communication protocol.
Prof. Nishi described a security framework for IEEE P1451.1.6 sensor networks including an architecture, a security policy with six security levels, and a format for security TEDS. Prof. Nishi also introduced a new MQTT service to manage access control lists across the sensor network. The framework was implemented and demonstrated with a hardware prototype using two sensors communicating through an MQTT broker.
