FPGA component with cryptographically coded bit rate, has SMK, is confidential master key, DI is serial number used outside component and is hash image which is confidential and RESM is produced by hash function

摘要

The component is provided with an identification module. The SMK is a confidential master key, DI is the serial number used outside the component and H1 is a hash image which is confidential. RESM is produced by the hash function H2. CHt is a coincidental request of the examiner. The composition of RESM and S0 as (S0/RESM) squared by a Rabin lock results in a coded identity (S0/RESM). The m is an integer is, and factors p and q are known only to the examiner. The examiner can compute the combination of (S0/RESM) and thus by comparison from RESM by using a smart card, and states that the component is genuine. Independent claims are included for the following: (1) smart card for verification, generates a secret identity (2) a common key, generates Ki in three sizes with component and with examiner (3) methods for developing a selling scenario (4) method for using a verification machine instead of verification-smart-card (5) a test protocol (6) an examining working graph (7) a general structure for mutual authentication by combination of open and confidential keys (8) rabin lock used in connection with fuzzy multiplication (9) method involves hardware section for users (10) auxiliary signature for DS1 and DS2 and (11) security of the system can be separated from the manufacturer by certifying the components.
