A novel security architecture of electronic vehicle system for smart grid communication

As ICT is incorporated into the existing electrical grid, security threats can also be unintentionally introduced to the Smart Grid, as has happened with conventional information and communication networks. To avoid this, a new security architecture design addressing the particular characteristics of ICT is required. This paper proposes a logical architecture considering the case of electric vehicle telecommunication, which is one of the core Smart Grid services and one closely related to actual users. Based on that architecture, we analyzed the security threats and the respective security measures required to respond to them. By analyzing the security techniques and algorithms applicable to the Smart Grid environment and applying them to address its security requirements and threats we proposed a new security architecture for Smart Grid.
