Deployment of data generation devices such as sensors and smart meters have been accelerating toward the vision of smart grid. The volume of data to be collected increases tremendously. Secure, efficient, and scalable data collection becomes a challenging task. In this paper, we present a secure and scalable data communications protocol for smart grid data collection. Under a hierarchical architecture, relay nodes [also known as data collectors (DCs)] collect and convey the data securely from measurement devices to the power operator. While the DCs can verify the integrity, they are not given access to the content, which may pave the way for third party providers to deliver value-added services or even the data collection itself. We further present optimization solutions for minimizing the total data collection time.Index Terms-Data collection with time minimization in the smart grid, scalable data collection in the smart grid, secure data collection in the smart grid.

Message authentication has vital significance for dynamic microgrid partition in smart grid. However, current message authentication protocols based on ''public key infrastructure'' are too complicated to be deployed in smart grid and lack group information management function. On the other hand, group information management protocols based on ''logic key hierarchy'' need to broadcast a lot of messages during microgrid partition processes, resulting in high communication costs. To address these issues, we present a novel identity-based message authentication protocol for dynamic microgrid partition called securing dynamic microgrid partition. Similar to the protocols of this field, securing dynamic microgrid partition can provide message authentication and group information management functions. However, compared to other well-known approaches, securing dynamic microgrid partition uses Bloom filter for managing group information, which can reduce the communication cost of logic key hierarchy significantly. Moreover, securing dynamic microgrid partition uses Lagrange interpolation for designing new identity-based signing and verification algorithms, which is simple to be deployed in smart grid environment and much more efficient than current identity-based protocols. Experimental results show that the proposed approach is feasible for real-world applications.

“…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. Another scheme based on shared secrets is [16], which can also support unicast, multicast and broadcast communications. The Smart Grid is divided into two levels, based on the computational resources of its devices, and each level has its own key management system.…”

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.
