“…The scheme proposed in [13] introduces an efficient and scalable key management protocol for secure unicast, multicast, and broadcast communications in Smart Grids; its operation is based on a binary tree to manage secret keys shared among entities. This proposal does not scale well, since it requires substantial manual work in order to create the binary tree and transmit it together with the secret values to every node; moreover, as nodes join or leave the network, the whole network should update the broadcast keys.…”

Abstract. As Smart Grid deployments emerge around the world, their protection against cyberattacks becomes more crucial. Before protective measures are put into place, one of the main factors to be considered is key management. Smart Grid poses special requirements compared to traditional networks; however, the review of previous work reveals that existing schemes are not complete. Here we propose a scalable and distributed key management scheme for the Smart Grid based on the Web-of-Trust concept. Our proposal is build on top of a Distributed Hash Table for efficient lookups of trust relationships. The target of this scheme is to create a key management system for the Smart Grid without the need of an always available Trusted Third Party. The underlying Distributed Hash Table can be further utilised as an infrastructure to build other Smart Grid services on top of it, like secure and/or anonymous aggregation, billing, etc.

“…In [1], a network architecture is presented for smart grids that consist smart meters, sensors (to detect faults), etc. In [2], a two way communication network system is presented which consists of a macro grid, that is a traditional centralized power grid, and a micro grid that represents a decentralized community-scale power grid. In [4] an illustrative macro smart grid is presented but it was not detailed since it was developed for educational purposes.…”

AbstractaThe traditional electrical power grid used to be one-directional power flows (flowing from producers to consumers). Nowadays, the consumers become more active and they participate in electricity generation process through Demand -directional and production units more decentralized. Electrical grid architectures must be developed in parallel in order to meet these increasing changes that lead to what is known to be Smart Grids. In this paper, we first present a literature review about the smart grid architectures and the various associated models. Then, we propose a closed loop supply chain approach to model and optimize configurations and operations of smart grid systems. Within this context, a whole section is devoted to the development of a mixed nonlinear programming model to optimize the architecture of given smart grid systems. For illustrative purposes, using a specific smart grid system and appropriate data, we model the problem and solve it for the optimal architecture.

In the last few years, we have witnessed a growing interest and increasing investments in smart grid technologies around the world. One of the key characteristics of the smart grid is its support for bi-directional information flow between the customer's premise and the utility provider using Internet Protocol-based technologies. The bi-directional nature of information flow has however opened up various security and privacy challenges which are being addressed by many recently proposed security solutions. Key management is often an important component of many of these solutions. We review recently proposed key management solutions aimed for the smart grid environment and highlight their practical implications along with their benefits and shortcoming.
