The device transfers a PUF key from the PUF unit to the secure module, over the interconnect system. In order to do this, the secure module generates a random value. The secure module then sends the random value to the PUF unit. The PUF unit then performs a bitwise XOR operation between the received random value and the PUF key, to generate a masked value. The PUF unit then transfers the masked value over the interconnect system to the secure module. The secure module then unmasks the PUF key by performing a bitwise XOR operation between the received masked value and the random value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"PUF key transfer","description":"An integrated-circuit device comprises a physical-unclonable-function (PUF) unit, a secure module, and an interconnect system communicatively coupled to the PUF unit and to the secure module.
