An Efficient and Privacy-Preserving Authentication Protocol for HAN
The SG (Smart Grid) system provides advantages for its stakeholders, which can not only reduce wasted energy and maintenance cost but also increase reliability with transparency during delivering electricity from suppliers to customer. The HAN (Home Area Network), consisting of smart appliances, smart meter and management system; can enable an end-user to remotely control many digital appliances. However, anyone can easily eavesdrop communication between the components of the HAN due to wireless communication to support easy and quick connection. As a result, the adversary easily identifies the type of appliances which belongs to the end-user by the energy consumption pattern.
