- 72. What is AWS IoT • The Amazon AWS IoT service enables secure, bidirectional communication between IoT devices and the cloud over MQTT, HTTP and WebSockets. • IoT devices are authenticated using AWS IoT service-provided X.509 certificates. Once a certificate is provisioned and activated it can be installed on a device. The device will then use that certificate to send all requests to AWS MQTT. 72
- 73. AWS Security Overview 73 AWS IoT Services & Authentication Host processor Application AT Command STM32 TCP/IP Wi-Fi TLS MQTT Certs & Keys IoT Node
- 74. What is MQTT • MQTT stands for MQ Telemetry Transport. It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks. • The design principles are to minimize network bandwidth and device resource requirements whilst also attempting to ensure reliability and some degree of assurance of delivery. These principles also turn out to make the protocol ideal of the emerging “machine-to-machine” (M2M) or “Internet of Things” world of connected devices, and for mobile applications where bandwidth and battery power are at a premium.
