1. A resilient device authentication system for use with one or more managed devices each including a physical unclonable function (“

  • PUF”

    ), the system comprising;

    one or more verification authorities (“

    VAs”

    ) each including a VA processor and a VA memory loaded with a complete verification set (“

    loaded CVS”

    ) that includes hardware part-specific data associated with the PUFs of the one or more managed devices and further includes metadata, the VA processor being configured to create a limited verification set (“

    LVS”

    ) by performing one-way algorithmic transformation of hardware part-specific data together with metadata from the loaded CVS so as to create a LVS that represents both metadata and hardware part-specific data adequate to redundantly verify all of the hardware parts associated with the LVS; and

    one or more provisioning entities (“

    PEs”

    ) each connectable to at least one of the one or more VAs, each PE including a PE processor and a PE memory loaded with a LVS, and configured to select a subset of the LVS loaded in the PE memory so as to create an application limited verification set (“

    ALVS”

    ).
