Smart metering and wireless communication technologies offer immense possibilities for scalable solutions to automated meter reading and energy production and distribution networks (smart grid). Around the world, researchers are working on methods for securing smart grid operations in general and smart metering in particular. Yet, their main focus remains on implementing and evaluating wireless communication technologies as an adequate solution to the smart grid. This paper proposes a security framework within the smart grid communication network. A new security profile called ‘W’ profile is introduced to cover all aspects of security protocols for Wireless M-Bus. Specifically, it aims to secure automated meter reading (AMR) using the Wireless M-Bus protocol within the Open Metering System (OMS) security standards in terms of authentication, integrity, and confidentiality.
