SYSTEM AND METHOD FOR ENSURING FORWARD amp; BACKWARD SECRECY USING PHYSICALLY UNCLONABLE FUNCTIONS

摘要

Methods and systems for ensuring forward and backward secrecy in an encrypted communication protocol are provided herein. In some embodiments, a method for ensuring forward and backward secrecy in an encrypted communication protocol includes extracting, from a first device, a unique physically unclonable function (PUF) value of the first device based on structural properties of the first device, creating a PUF key pair including a first public key and a first private key that are generated based on the PUF value, deriving a first session key using the PUF key pair, deleting the first public key and the first private key, and sending a first encrypted communication to a second device using the derived session key.
