    摘要: An authenticated RFID system is provided that uses elliptic curve cryptography (ECC) to reduce the signature size and read/write times when compared to traditional public key implementations such as RSA. Either ECDSA or ECPVS can be used to reduce the signature size and ECPVS can be used to hide a portion of the RFID tag that contains sensitive product identifying information. As a result, smaller tags can be used or multiple signatures can be written at different stages in a manufacturing or supply chain. A key management system is used to distribute the verification keys and aggregate signature schemes are also provided for adding multiple signatures to the RFID tags, for example in a supply chain.

    摘要: A key injection service module for an asset management system is provided for a secure means of injecting keys into products. To provide this service, a controller is used to define one or more key types defining the format of the keys in a file. The controller is then used to define a product model, and then to bind each key type to the product models.

    摘要: An asset management system is provided which comprises one or more controllers, which operate as main servers and can be located at the headquarters of an electronic device manufacturer to remotely control their operations at any global location. The controller can communicate remotely over the Internet or other network to control one or more secondary or remote servers, herein referred to as appliances. The appliances can be situated at different manufacturing, testing or distribution sites. The controller and appliances comprise hardware security modules (HSMs) to perform sensitive and high trust computations, store sensitive information such as private keys, perform other cryptographic operations, and establish secure connections between components. The HSMs are used to create secure end-points between the controller and the appliance and between the appliance and the secure point of trust in an asset control core embedded in a device.

    摘要: An infrastructure for securely communicating with electronic meters is described, which enables secure communication between a utility and a meter located at a customer, over a communication link or connection such as via a network. This enables messages to be sent from the utility to the meter and vice versa in a secure manner. The network provides a communication medium for communicating via the C12.22 protocol for secure metering. A cryptographic backend is used to cryptographically process messages to be sent to the meter and to similarly cryptographically process messages sent from the meter. By providing appropriate cryptographic measures such as key management, confidentiality and authentication, the meter can only interpret and process messages from a legitimate utility and the utility can ensure that the messages it receives are from a legitimate meter and contain legitimate information.
