Abstract

The Smart Grid is an electrical power infrastructure that makes intelligent decisions about the state of the electrical power system to maintain a stable environment. It is expected that the smart grid will radically add new functionalities to legacy electrical power systems. However, believe that this will in turn introduce many new security risks. With the smart grid’s backbone communication networks and sub networks, there are possible scenarios when these sub networks can become vulnerable to attacks. Ensuring security in these networks is challenging because most devices are resource constrained. In addition, different protocols that are used in these networks use their own set of security requirements. In this article, the securities Requirements of smart grid communication networks are firstly identified. The public key infrastructure (PKI) is a viable solution; it has some difficulties to satisfy the requirements in availability, privacy preservation, and scalability. To complement the functions of PKI, introduce some novel mechanisms so that those security requirements can be met. In particular, propose a mechanism to efficiently resist Denial-of-Service (DoS) attacks, and some suggestions to the security protocol design for different application categories.
