CREATING SECURE MULTIPARTY COMMUNICATION PRIMITIVES USING TRANSISTOR DELAY QUANTIZATION IN PUBLIC PHYSICALLY UNCLONABLE FUNCTIONS

摘要

A security method includes securely exchanging information related to delays of logic gates of a plurality of security primitives, and configuring a first and a second security primitive such that the delays associated with a subset of logic gates of the first and second security primitives match, for secure communication between the first and second security primitive. The security method may further include configuring the first security primitive and a third security primitive such that the delays associated with a subset of logic gates of the first and third security primitives match, for secure communication between the first and third security primitive. The security method may further include switching the configuration of the first security primitive in one clock cycle between the configuration for secure communication with the second security primitive and configuration for secure communication with the third security primitive.
