IIoT Security - Integrated SIM for Supporting Public and Campus Networks

Lecture electronica Conferences > Wireless Congress > Session 11: Security

14:25-14:50 h | Virtual

With the advance of massive machine type communication (mMTC) devices also in critical domains like Industrial Internet of Things (IIoT) and Industry 4.0, security concerns become of even more importance. Here, not only secure connections, but also trusted identification and processing needs to be considered carefully. In cellular networks, secure elements and subscriber identity modules (SIM) are widely used and have proven to be suitable secure building blocks. With the usage of cellular communication in industrial environments, these elements have to address two new challenges: (a) the SIM card needs to be highly integrated and also adoptable to cost sensitive devices and (b) provisioning needs to be supported in both public but also the new field of campus network. Existing solutions as eSIM are not directly applicable given cost, complexity, and functionality. Here, the new approach of integrated SIM solutions are setup to address these requirements. This shows in particular promising for 3GPP mMTC standard NB-IoT, which strives to connect hundred thousand of devices in once cell, while supporting lowest power consumption and wide range in cost sensitive devices. By analyzing the security requirements of these NB-IoT devices, complexity reduction can be achievement without compromising security. One very compelling approach into this direction has been proposed by Deutsche Telekom with the nuSIM standard. This standard is supported by a strong industry consortium of operators, MNOs and device manufactures. Leveraging this eco system, IIoT devices can be built into machines, goods or infrastructure and provisioned at a very late stage of the roll-out - e.g. in the fab's target country - without physical changes or manual interaction. Furthermore, this integrated SIM approach provides the foundation for supporting both public and campus networks. Profiles of both domains can be stored and exchanged depended on the actual usage. This is in particular of importance, as the new setup of supporting coexistence of both 3GPP public and campus operators have to be considered. In this presentation, different use cases in the industrial domain will be analyzed regarding topology and security needs. The derived requirements are taken to judge different implementation approaches and to outline a suitable solution.
