Query: MQT-TZ: Secure MQTT Broker for Biomedical Signal Processing on the Edge   Physical health records belong to healthcare providers, but the information
contained within belongs to each patient. In an increasing manner, more
health-related data is being acquired by wearables and other IoT devices
following the ever-increasing trend of the "Quantified Self". Even though data
protection regulations (e.g., GDPR) encourage the usage of privacy-preserving
processing techniques, most of the current IoT infrastructure was not
originally conceived for such purposes. One of the most used communication
protocols, MQTT, is a lightweight publish-subscribe protocol commonly used in
the Edge and IoT applications. In MQTT, the broker must process data on clear
text, hence exposing a large attack surface for a malicious agent to
steal/tamper with this health-related data. In this paper, we introduce MQT-TZ,
a secure MQTT broker leveraging Arm TrustZone, a popular Trusted Execution
Environment (TEE). We define a mutual TLS-based handshake and a two-layer
encryption for end-to-end security using the TEE as a trusted proxy. We provide
quantitative evaluation of our open-source PoC on streaming ECGs in real time
and highlight the trade-offs.
