Secure and Scalable Data Collection With Time Minimization in the Smart Grid

Abstract

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.

Design and microcontroller‐based hardware performance analysis of a security‐enhanced lightweight communication scheme for smart grid

“…Since the other schemes , did not mention the storage space, here, we only compare our scheme with Liu et al's scheme, our previous scheme, and Li et al's scheme …”

“…For Uludag et al's scheme, the transmitted messages include the and . Hence, the total communication cost of Reference is (128 × 96) + (128 × 96) + (128 × 96) + (256 × 96) + (128 × 4) + (1024 × 4) + (128 × 4) bits = 8.125 KB.…”

“…Therefore, the proposed authentication or communication scheme should be as light as possible placing minimal burden on the SMs. Lightweight authentication and communication schemes have been discussed by some papers , . In 2011, Fouda et al addressed the sniffing on SMs, traffic analysis, denial of service (DoS) attack, DoS buffer overflow attack, reconfigure attack, spoofing, man in the middle attack, and the replay attack as the security threats, which exist in the smart grid communications.…”

A comprehensive overview of cyber-physical systems: from perspective of feedback system

“…A new metric to measure the security of information transmission is introduced to adapt the dynamic of CPS in [89], and fundamental limit to guarantee the security is also analyzed. For large scale CPS communications, to meet the scalability, extensibility, and thinness requirements, [90] designed a resilient end-to-end message protection framework by exploiting the notion of the long-term key that is given on per node basis. The scheme in [91] can improve secure communications without compromising scalability and endto-end security.…”
