Design and Development of Secured Communication Between Smart Meter and Neighborhood Gateway

Abstract

A smart meter is an advanced meter which measures power consumption in much more accurately than a conventional meter and communicates the collected information back to the usage for load limit and tariff purposes. The objectives are privacy that nobody can obtain power usage of other person’s information if the protocol is accurately executed. Real time authentication that transmitted message can be real timely authorized by the receiver which is essential to resist against the denial of service (DoS) attack, Replay attack resistance that receiver can validate whether the received messages are the replay of previously authorized persons. The main objective of this new technology is the bidirectional flow of information. The smart meters send the power consumption reports to the power operator and also control instructions are sent from electricity board in order to be executed by the smart meters. In between, there consists of some gateways which are responsible for data accumulation. The main objective of the system is the communication of smart meter and neighborhood gateway. The presented communication scheme must consider the necessity for consumption reports transmission in short time intervals, and also it must consists of both security and the limited resources of smart meters. This implemented system demonstrates substantial reduction in storage space and data modifications are avoided.
