Reliable and Adaptive Distributed Public-Key Management Infrastructure for the Internet of Things

The Internet of Things (IoT) is an emerging paradigm in the world of computer networks, where physical objects are connected over the Internet. Given the huge number of connected devices that are potentially vulnerable, highly significant risks emerge around the issues of communication security. Unfortunately, the conventional security methods are hard to adapt due to the heterogeneity and resource-constrained objects. In this paper, we propose a reliable and adaptive distributed public-key management infrastructure for the IoT. The main purpose of our proposal is to mitigate the resource issue for public-key certificate management to design an effective security mechanism, which offers reliable end-to-end security services. In order to evaluate the performances of our proposal, we have conducted intensive simulations with comparison to the literature, in which we have obtained promising results in terms of storage, communication, response time and resilience against malicious nodes.
