Abstract
A system and method for configuring and registering a cryptographic device. The configuration phase involves loading a device serial number (DSER) and a symmetric key (SK) into non-volatile memory of the cryptographic device. The non-volatile memory is integrated with processing logic of the cryptographic device. DSER is provided by an external source while SK is generated within the cryptographic device. The registration phase involves providing DSER to a database that contains cryptographic information associated with each cryptographic device manufactured. The cryptographic information includes at least a public key and a private key encrypted with SK. DSER is used to locate the appropriate cryptographic information and to transmit the cryptographic information to an electronic system having the cryptographic device.
