Patent ID: 7761910

Claim:
An energy management device for use in an energy management architecture for managing an energy distribution system, the energy management architecture comprising a network, the energy management device comprising: an energy distribution system interface operative to couple the energy management device with at least a portion of the energy distribution system; a network interface operative to couple the energy management device with the network for transmitting outbound communications to the network and receiving inbound communications from the network, the inbound communications comprising first energy management data and the outbound communications comprising second energy management data; a memory comprising a first private key, the first private key being related to a first public key such that data may be at least one of encrypted with the first public key, signed with the first private key, or combinations thereof, wherein data encrypted with the first public key may be decrypted only with the first private key and data signed with the first private key may be authenticated only with the first public key; and a processor coupled with the network interface, the energy distribution system interface and the memory, the processor operative to perform at least one energy management function on the at least the portion of the energy distribution network via the energy distribution system interface, the processor further operative to process the first energy management data and generate the second energy management data based on the at least one energy management function, the processor being further operative to decrypt the first energy management data using the first private key where the first energy management data has been encrypted with the first public key.
