Internet of Things

The Internet of Things is growing fast by the addition of smart devices by different manufacturers and owners. Recent improvements in interoperability enable new applications that rely on exchanging information between the various smart devices of different manufacturers and owners. However, when information is exchanged beyond an entity's infrastructure, verifying the authenticity and integrity of data is a challenge. Furthermore, to achieve auditability, some applications require an immutable log. Distributed Ledger based Public Key Infrastructures are a promising approach to solve these challenges. However, the limited available resources of IoT devices constrain the applicability of common DLTs, and lightweight solutions are required. In this research, we investigate DLT based PKIs for the Internet of Things. Primarily, we focus on solutions that meet the requirements of low power networks.
