A Physical Unknown Function (PUF) is a function that is easy to evaluate but hard to characterize. We introduce controlled physical unknown functions (CPUFs) which are PUFs that can only be accessed via an algorithm that is physically bound to the PUF in an inseparable way. Controlled PUFs enable several applications including certified execution, where a certificate is produced that proves that a specific computation was carried out on a specific processor. Certified execution has many… CONTINUE READING
