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.
