Public Key Infrastructure Using Wireless Communication Networks

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. In addition, different protocols that are used in these networks use their own set of security requirements. 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.
