Abstract:
1. A method of validating a customer certificate used for enabling software booting of a chipset, said method comprising: maintaining a software boot identification (CCID) in one-time-programmable (OTP) memory within the chipset, wherein the CCID comprises a multi-bit value having two or more CCID customer identifications (CIDs) contained at customer-specific index positions within the multi-bit value; obtaining a certificate CID and a certificate index value from the customer certificate; reading an OTP CID from the CCID by indexing into the CCID according to the certificate index value; determining whether the customer certificate has or has not been revoked based on evaluating the OTP CID with the certificate CID; and disallowing software booting of the chipset, if the customer certificate is determined as having been revoked.
