The solution aims to ensure security of an IoT network and spans three major technological areas – security, IoT, and Blockchain. Underlining Sasken's DNA of innovation, this patent addresses the security problem for IoT Edge Network and provides a means of automatic (zero-touch) provisioning and registration of bona fide IoT devices. The lack of security and manual provisioning of devices in IoT is both a concern and bottleneck for accelerated adaption of IoT.
