Abstract
The Internet of Things (IoT) is on the rise. Today, various IoT platforms are already available, giving access to myriads of things. Initiatives such as BIG IoT are bringing those IoT platforms together in order to form ecosystems. BIG IoT aims to facilitate cross-platform and cross-domain application developments and establish centralized marketplaces to allow resource monetization. This combination of multi-platform applications, heterogeneity of the IoT, as well as enabling marketing and accounting of resources results in crucial challenges for security and privacy. Hence, this article analyses the requirements for security in IoT ecosystems and outlines solutions followed in the BIG IoT project to tackle those challenges. Concrete analysis of an IoT use case covering aspects such as public, private transportation, and smart parking is also presented.
