摘要： A system and method for producing cryptographic keys for use by an embedded processing device within a manufactured product. A pseudo random number generator is seeded with entropy data gathered by the embedded device, and the result is used to generate a public-private key pair. The process can be carried out during manufacturing so that the public key of each manufactured product can be stored in a database along with a unique identifier for the embedded device associated with the key. In one particular example, a vehicle having an installed telematics unit uses the key generating process to self-generate keys using entropy data available to the vehicle.

摘要： A method and communications system for generating and using compact digital certificates for secure wireless communication. Each compact certificate includes a digital signature and only a portion of the data used in generating the signature. The remaining certificate data is pre-stored on one or more wireless devices for which secure communication is desired. Upon receiving a compact certificate, the wireless device authenticates the certificate using its digital signature along with both the data contained in the certificate and the data pre-stored on the wireless device. This approach permits secure connections to be established between wireless devices using relatively small digital certificates.

摘要： A system and method for validating a software file to be installed into a controller. The method includes preparing the software file including assigning a software version code to the software file, assigning a security version code to the software file, and signing the software file with the software file version code and the security version code. The signed software file is presented to the controller for installing on the controller and the controller verifies the software file signature to determine if the software file is valid and the security version code is valid. The controller allows the software file to be installed in the controller if both the signed software file is valid and the security version code is valid.

摘要： A system and method for securely flashing a controller, where the controller includes at least one main processor and at least one secondary processor, and where the processing duties are distributed between the processors. A programming tool provides a content file to be flashed and a digital signature to the controller. The controller calculates a hash value of the content file, decrypts the digital signature using a public key to generate a decrypted hash value, compares the decrypted hash value to the calculated hash value, and determines that the content file is valid if the decrypted hash code matches the calculated hash value, where one or more of the steps of calculating the hash value, decrypting the digital signature, comparing the decrypted hash value to the calculated hash value and determining that the content file is valid, is performed by the main processor for the secondary processor.
