It is recognized herein that current messaging protocols for internet of things (IoT) architectures are often weak from a security perspective, and are often poorly suited for resource-constrained devices. An example IoT system described herein combines device authentication and application-layer key establishment using facilities of IoT messaging protocols. The IoT system may include a Trust Broker, which acts as a registration point for devices, and an edge gateway, which manages communication between a given device and the trust broker (and IoT servers). The edge gateway may acquire a trusted role, such that it may be a secure intermediary for device-server messaging, and such that it can facilitate authentication of devices to services.
