advanced metering infrastructure (ami) is a key part of the smart grid; thus, one of the most important concerns is to offer a secure mutual authentication.  this study focuses on communication between a smart meter and a server on the utility side. hence, a mutual authentication mechanism in ami is presented based on the elliptic curve cryptography (ecc) and one time signature (ots) consists o...

Public communication is secure if a hostile third party cannot detect the informational content of the messages exchanged by the communicating parties. In Nash equilibrium, communication by computationally unbounded players cannot be secure. We assume complexity averse players, and show that a simple, secure and costless communication protocol becomes available as the marginal complexity cost t...

This paper describes aspect-oriented secure connectors for implementing secure software architecture for distributed business applications. A secure connector for secure software architecture can be designed separately from application business components by considering different communication patterns between the components as well as security services required by application components. In th...

Smart grid concept is introduced to modify the power grid by utilizing new information and communication technology. Smart grid needs live power consumption monitoring to provide required services and for this issue, bi-directional communication is essential. Security and privacy are the most important requirements that should be provided in the communication. Because of the complex design of s...

Providing authentication for the messages exchanged between group members in addition to confidentiality is an important issue in Secure Group communication. We develop a protocol for Secure Authentic Communication where we address authentication for the group communication scheme proposed by Blundo et al. which only provides confidentiality. Authentication scheme used is a multiparty authentic...

Secure and trusted group communication is an active area of research. The growing importance of group communication based applications fuelled its popularity. The central research challenge is secure and efficient group key management. . The main issue in secure group communication is group dynamics and key management. A scalable secure group communication model ensures that whenever there is a...

This paper aims towards synchronization of Bhalekar-Gejji chaotic system and its application to secure communication. Synchronization is achieved using suitable nonlinear active control (NAC) scheme. Proposed synchronization is used to achieve secure communication using NAC. For secure communication, the information signal is masked with one of the state of chaotic system at transmitter end and...
