Abstract
A device authentication system including one or more devices, child servers capable of communicating therewith, and a root server configured to enroll devices by: collecting device-specific tokens and creating a complete verification set ('CVS') therefrom; creating a working verification set ('WVS') by selecting a subset of the CVS; creating a limited verification set (“LVS”) by performing a derivation function on at least part of the WVS; and distributing part or all of the LVS to child servers. A device authentication system configured such that a PUF-containing device and a server communicating with the device can perform an extended BPV generation. A device authentication system that includes a device containing a PUF and is configured to perform error decoding on subsets of an authentication-related value multiple times.
