Abstract
Security is essential to enable the Internet of Things (IoT). The security of the traditional Internet has been enhanced by well-developed security measures, for example, the SSL/TLS protocol suites. However, authentication based on certificates provided by certificate authorities (CA) cannot, in current form, scale to the expected 50 billion devices. To make TLS with CAs more scalable, the Let's Encrypt project(https://letsencrypt.org) launches free and automated CAs. Nevertheless, the point-to-point nature of TLS connections and overhead of managing certificates still make it challenging to apply TLS for all IoT devices, possibly with resource constraints and one-to-many communication requirements. Moreover, TLS itself is not designed for frequent authorization/revocation which might be necessary for some safety-critical IoT devices. To address these issues, we propose a secure network architecture with key distribution mechanisms using local, automated authorization entities. The architecture provides security guarantees while addressing IoT-specific issues including resource constraints. By evaluation, we show that the architecture's overhead scales sublinearly and works well with resource-constrained devices. We also expect the proposed architecture can be integrated easily with free, automated, and scalable CAs by the Let's Encrypt project.
