PUF (Physical Unclonable Function) is a physical property based on the molecular structure variation of same materials. The variation causes sophisticated differences generated the manufacturing process.
Same DesignSame FunctionSame Wafer
PUF is created through the chip manufacturing process. It utilizes its unavoidable and uncontrollable variations at a molecular level, which creates each chip unique.
Unique & Unclonable
PUF maintains its uniqueness throughout the manufacturing process.
The functionality of PUF is based on a challenge-response mechanism in which the mapping between a challenge and the corresponding response is dependent on the complex and variable nature of a physical material.
Secured Data Encryption in PUF SolutionPUF supports the secured working structure of a system
Architecture & Form Factors
Seamless System Design for Direct & Instant Cryptography PUF provides as various form factors
PUF Features : Non-repudiation
Non-repudiation structure is gratified with the electronic signature
PUF value never leaves the chip; unique PUF value makes the carrier of the PUF the only possible transaction maker
PUF Features : Distribution of Liability
Server-side liability is greatly reduced
PUF enables “each device generates its own private key”; server only checks the validation of the device throughout the public key communication
