Patent ID: 8844009

Claim:
A resilient device authentication system, comprising: a. one or more verification authorities (“VAs”) including a central processing unit and a VA memory loaded with a complete verification set (“loaded CVS”) that includes hardware part-specific data, and configured to perform one-way algorithmic transformation of hardware part-specific data in said loaded CVS and create a limited verification set (“LVS”) from said loaded CVS; b. one or more provisioning entities (“PEs”) each connectable to at least one of said one or more VAs, including a central processing unit and a PE memory loaded with a LVS, and configured to select a subset of said LVS loaded in said PE memory so as to create an application limited verification set (“ALVS”); and c. one or more managed devices each associated with corresponding hardware part-specific data in said loaded CVS, said managed devices including hardware part-specific information; wherein said one or more VAs are configured to create a replacement LVS.
