Abstract
Digital signatures are applied to metered energy data that is collected by a common data collection system. The system receives data from meters that may be owned by one or more utilities. The data is stored by the system using public key cryptography to ensure that it is only accessible by the intended consumer of the data. When the data is transmitted to the intended consumer, it is digitally signed by the system to ensure the authenticity of the data as received by the consumer.
