Connectivity of everyday objects is on the rise forming the so-called Internet of Things (IoT). Different domains such as vehicular and smart home networks will be linked together requiring new strategies to support interoperability. The Information-Centric Networking (ICN) paradigm is a promising candidate to form a harmonized ecosystem across different IoT domains. As ICN exploits caching and does not rely on continuously available end-to-end connectivity between a producer and a consumer of data, enabling access control and other security features in an ICN is a special challenge. This paper introduces the mechanism EnCIRCLE — Encryption-based access Control for InfoRmation-centric Connected vehicLEs. EnCIRCLE is an approach which can provide access control and other security features in ICN-based IoT systems. We apply EnCIRCLE to a vehicular system, which is especially challenging due to mobile and intermittently connected network participants.
