PUF is a cutting-edge technology that creates a unique security key during the chip manufacturing process, at the micro-level. This key is impossible to modify or duplicate.
Hardware Root of Trust(HRoT)
The Hardware Root of Trust is a set of core functional elements consisting of hardware and software components that are trusted and cannot be altered during the lifetime of the product. It is something that the computer's operating system can rely on all the time, in any circumstances.
What is PUF?
PUF stands for Physically Unclonable Function. It is a term referring to "functions that cannot be physically duplicated." PUFs are immutable functions that cannot withstand any hacking attempt, and are the basis of IoT security solutions. Since each semiconductor chip generates a different unique ID, it is called the fingerprint of the semiconductor.
What is Unique?
There are various PUF technologies, but most of them are implemented using active devices, which are sensitive to PVT (process, voltage, temperature) changes and are accompanied by an aging effect. To overcome this, an ECC (Error Correction Code) logic function must be additionally introduced.
What can you do?
Secure Inborn ID provides a service platform using UUID Secure Inborn ID, such as non-replicable fingerprints based on the chip's unique HW characteristics. It also generates keys and certificates using a hardware block in a clone proof secure ID-based security chip, and supports cryptographic algorithms using hardware.
