With the growth in IoT devices and connected solutions, effective security approaches must incorporate hardware and software security mechanisms. These mechanisms require strategies for securing devices, and their identities, which use strong cryptographic techniques combined with trusted hardware, such as a hardware security module. Hardware trustworthiness becomes the foundational building block for software features and solutions built on top of the hardware. The supply chain is susceptible to a range of threats, such as counterfeit hardware, IP piracy, overproduction, reverse engineering, cloning, and software-based threats, such as unreliable data and unauthorized manipulation of software and data. Some of the points covered are:

Approaches to using trusted hardware
Application of hardware-based security for key management
Attestation of the hardware and software trustworthiness
Using secure hardware roots of trust to enable supply chain security
Providing supply chain confidence throughout the product lifecycle
Zero Touch Provisioning of the device in the operational environment

This session discusses the challenges and possible solutions in ensuring supply chain security for IoT devices. A few of the industry initiatives for supply chain assurance are also introduced.
