A cloud based security management scheme for home area network (HAN) in the smart grid

The HAN energy management system (HAN ems) and Smart Grid energy management system (SG ems) are moved to cloud through virtualization technique, where the cloud provides monitoring and control of smart home appliances. Since the HAN communication with the cloud involves private data from home, security and privacy of that data are deemed important factors. In this paper, we have spilled light on the management of security for HAN smart appliances and data exchanged between the HAN ems at cloud and smart meter system at home through cryptographic mechanisms.
