The hardware root of trust (HRoT) provides the trust base (root key), hardware identifier (UID), hardware unique key (HUK), and entropy required for the secure operation of the entire chip and therefore is often the focus of hacker attacks. If the design can’t effectively resist attacks, hackers can easily obtain the secrets of the entire chip. Attackers can use the secrets to crack identity authentication and data encryption and steal product design know-how, causing application security problems.
This article will discuss how to strengthen the security of AI systems from the structure of the AI hardware device, to the security requirements, solutions, and etc. To do this, we will use PUFsecurity’s hardware root of trust module, PUFrt, as an example to help readers understand how combining AI application architecture and physical unclonable function (PUF) can benefit hardware security technology.
With the invention of Physical Unclonable Functions (PUF), we can now create a unique, inborn, unclonable key at the hardware level. The natural follow-up question to this is, “but how do we protect this key?” It is like storing your key to secrets in a drawer, a surefire way to break the secure boundary and create vulnerabilities.
Currently, there is a strong belief among the cyber security experts that hardware security is imperative since it is more efficient, effective, reliable and tamper-resistant than software security. As a matter of fact, providing trusted execution environment (TEE) and embedding a hardware root of trust (HRoT) as the anchor are necessary to provide a firm foundation for electronic systems security.
A complete reinvention of the automotive industry is currently underway. Autonomous driving, connected vehicles, and the electrification of the powertrain all represent a once-in-a-generation shift in the manufacturing process.
The security of AIoT devices has become increasingly important. In order to ensure that the system’s security functions are working effectively and protecting every node and edge device from information security risks, it is important to generate a unique root of trust in the security system rooted in the chip.
