Implementation of Distributed Light weight trust infrastructure for automatic validation of faults in an IOT sensor network
The goal of the paper is to design and implement a distributed trust infrastructure, which makes use of the existing Internet Domain Name System (DNS) and its global trust anchor. Since it has high scalability and eases the burden on relying parties in turn, allows for highly efficient queries to support individual trust decisions. In this implementation, a stand-alone private DNS infrastructure including top level domains was developed with Raspberry Pi Cluster. Further, the security of the DNS for the trust infrastructure is enhanced by implementing DNSSEC and DANE protocol with TLSA resource records. It also includes the core functionality of the LIGHTest infrastructure like developing trust lists, Trust Scheme Publication Authority (TSPA) and a Delegation Publisher (DP). In this paper, a distributed trust infrastructure is developed and visualized practically by designing an infrastructure for validation and authentication of faults in the sensor system of an organization using a Raspberry Pi Cluster.
