Abstract: An energy monitoring device including procedures for secure communication of data from the device is disclosed. The energy monitoring device includes a public/private key pair used to encrypt and/or digitally sign communications by the device. This allows the receivers of these communications to authenticate the communications to ensure that the device and/or communications have not been compromised. The energy monitoring device is further capable of communications via an ad-hoc “mesh” network, thereby facilitating communications among devices which are substantially inaccessible due to either physical or economic limitations.

Abstract: The disclosed embodiments comprise a power quality analysis system, device, and method. The combination of at least one power quality parameter value, power quality event properties, non-power quality properties, and time properties is used to create power quality information that is descriptive of power quality events. The power quality information is easily configured and organized based on the desired options in order to make it more understandable and usable.

Abstract: A power management architecture for an electrical power distribution system, or portion thereof, is disclosed. The architecture includes multiple intelligent electronic devices (“IED's”) distributed throughout the power distribution system to manage the flow and consumption of power from the system. The IED's are linked via a network to back-end servers. Security mechanisms are further provided which protect and otherwise ensure the authenticity of communications transmitted via the network in furtherance of the management of the distribution and consumption of electrical power by the architecture. In particular, public key cryptography is employed to identify components of the architecture and provide for secure communication of power management data among those components. Further, certificates and certificate authorities are utilized to further ensure integrity of the security mechanism.

Abstract: A power management architecture for an electrical power distribution system, or portion thereof, is disclosed. The architecture includes multiple electronic devices distributed throughout the power distribution system to manage the flow and consumption of power from the system using real time communications. Power management application software and/or hardware components operate on the electronic devices and the back-end servers and inter-operate via the network to implement a power management application. The architecture provides a scalable and cost effective framework of hardware and software upon which such power management applications can operate to manage the distribution and consumption of electrical power by one or more utilities/suppliers and/or customers which provide and utilize the power distribution system.

Abstract: A system and method are disclosed for providing authentication of data source and integrity between applications and users in different Non Affiliated Entities/organizations while limiting access to resources between private networks of energy management devices. A Non Affiliated Entity (“NAE”) is an organization, individual or group of entities that may share some information with each other but are not closely tied, such as a group of competitor utilities. In conducting their operations, two or more applications or organizations (NAEs) may not fully trust one another, but wish to share some EM data and resources. These NAEs identify users, such as EM devices, using a “federated security” scheme that may be based on Kerberos, described above, which allows users from one NAE to be identified to another NAE. Web service security can be combined with federated security based authentication and access control to provide for secure exchange of EM data between users of different NAEs.

Abstract: A system and method for detecting and responding to device tampering in an EM device is disclosed. The EM device is provided with mechanisms to detect and indicate unauthorized tampering with the device. Further, in response to detected unauthorized tampering, the device may take actions to protect the integrity of data generated by the device as well as protect any confidential data stored within the device. Such actions may include preventing further device operation, generating warnings to the device owner/user, marking subsequently generated data as suspect, destroying stored confidential data, etc.
