From "Using Blockchain Technology to Secure the Internet of Things paper" Two weeks ago the CSA has released the white paper that should help companies in the IoT business to understand how to secure their IoT devices through the adoption of Blockchain technology. With this paper, CSA intends to suggest an architecture that overcomes the limits of these devices and solve their security problems. As you may know, IoT devices have limits in terms of memory, power consumption and CPU. Hence, they cannot be (as per today) nodes of a blockchain. With the proposed architecture these limits are bypassed. In fact, the blockchain nodes are maintained in the clouds, while the devices are provided by capabilities to secure enroll them in the network and to secure machine-to-machine communication. With this architecture, the IoT device manufacturer can assure a clean bootstrap into the blockchain network, and subsequently, other services like identity management, software update, ...
