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.
