Securely & Efficiently Integrating Constrained Devices into an ICN-IoT

Abstract

IoT is a significant recent development that aims to interconnect billions of internet-connected devices and sensors and requires high scalability and comprehensive security. This work provides an architecture based on Information-Centric Networking (ICN) to address security and scalability challenges in the Internet of Things (IoT). We present a framework and supporting protocols that extend prior work to address authentication, registration, secure forwarding, and service authorization and discovery of constrained devices into an ICN-based IoT in a highly scalable way. Our approach allows these constrained devices operating in low-power lossy networks to achieve this using pure ICN communications. The device nodes participating in our architecture are assumed to be constrained, so cryptographic operations are kept to a minimum using lightweight symmetric encryption functions while they rely on unconstrained coordinating nodes in concert with a security manager service to manage authentication, key distribution, and security oversight.
