Practical Internet of Things Security - Second Edition

Moving back toward the edge

CSPs are also enabling more capabilities at the edge. With more powerful microprocessors on the market, cloud services such as AWS Greengrass offer the ability to perform limited, event-based processing on-device. This reduces transaction latency, allowing the embedding of intelligent functions directly at the edge.

CSPs have also begun to strengthen the security of the edge-to-cloud connection. For example, Microsoft Azure's Zero Touch Provisioning service supports Trusted Computing Group (TCG) Device Identity Composition Engine (DICE) secure cloud connectivity. Using this specification, hardware manufacturers can embed cloud identities directly into silicon, supporting a secure registration and enrollment process ...
