Secure Identifiers and Initial Credential Bootstrapping for IoT@Work

Internet of Things is gaining momentum in industrial automation environments. The objectives of the EU project IoT@Work are to transfer Internet of Things approaches to industrial automation environments and to develop mechanisms and protocols to enable plug & work of devices. Identification of things or devices as part of a network, service, or application in a secure manner is one of the most important requirements for reliable operation. In this paper we present the requirements to secure identifiers and propose an approach suitable in industrial automation. As secure identifiers rely on cryptographic credentials, we compare different approaches to initially bootstrap these credentials and analyse applicability in Internet of Things scenarios.
