Secure Device Management and Device Attestation in IoT
V. Hari Santhosh, A. Babiyola, C. Chitra · 2024
The Internet of Things (IoT) refers to the ever-expanding network of electronic devices that are increasingly being built into commonplace items like household equipment, vehicles, and homes. The importance of secure device management and device attestation is rising along with the number of connected devices. Therefore, the reliability of IoT devices and the importance of cyber security are growing. One way to achieve the reliability of an IoT device is by device attestation, which provides quantitative confirmation of a device’s software’s integrity. Device attestation has great potential in the Internet of Things (IoT), but its widespread implementation is limited by a lack of service integration. The purpose of this chapter is to introduce the concepts of secure device management and device attestation and to explain how they can be used to increase the safety of IoT gadgets. This chapter discusses device management using a centralized management system. This system can provide a single point of control for managing IoT devices, making it easier to enforce security policies and monitor device behavior, thereby managing and securing IoT devices throughout their lifecycle. This includes tasks such as provisioning, configuration, firmware updates, and decommissioning. For example, a centralized management system can be used to deploy firmware updates to IoT devices, ensuring that they have the latest security patches. This system uses a Trusted Platform Module (TPM) or other hardware security module to authenticate the device. The TPM is a dedicated chip that stores and processes cryptographic keys in an encrypted fashion. By using a TPM, IoT devices can provide proof of their identity and integrity to other devices on the network thereby verifying the identity and integrity of an IoT device. This is important because it helps ensure that only authorized devices can access sensitive data and services.
