Abstract
A method and system for authenticating a first device is disclosed. The method includes the steps of: measuring a first response bit string of a physical unclonable function of the first device with respect to a challenge bit string, the physical unclonable function being provided by one of the processor of the first device and a further physical component of the first device; deriving a shared secret bit string from a uniformly distributed random vector; encoding a helper bit string by multiplying a uniformly distributed random matrix with the uniformly distributed random vector and adding the first response bit string to a result of the multiplication; and transmitting the helper bit string to a second device that is remote from the first device.
