With the rapid deployment of IoT devices, there is
an increasing concern on the security and privacy of the devices.
We are now witnessing newer and higher intensity attacks that
exploit IoT devices. Although security-by-design is important
and necessary, the effectiveness and sustainability of the buildin security defense may still be questionable. This has created
new opportunities for third-party security service providers to
enter the market. In this work, we leverage the distributed
ledger technology (DLT) to propose a solution for distributing IoT
security functions. We design the system architecture and describe
the different types of operations to be executed. Our system also
allows for reputation scoring that further adds credibility to the
security functions distributed in the network.
