Abstract: This article has given a broadbrush description of issues related to smart-grid security. Designing solutions in at this stage, before widespread deployment, would be beneficial; in some cases solutions exist, whereas in others research investments will be needed. Several open questions about goals still require discussion, especially around such topics as how (and how much) privacy can be supported.

Cyber-Physical Systems Security—A Survey
TL;DR: In this paper, the authors study and systematize existing research on CPS security under a unified framework, which consists of three orthogonal coordinates: 1) from the security perspective, they follow the well-known taxonomy of threats, vulnerabilities, attacks and controls; 2) from CPS components, they focus on cyber, physical, and cyber-physical components.

Time Valid One-Time Signature for Time-Critical Multicast Data Authentication
Qiyan Wang,Himanshu Khurana,Ying Huang,Klara Nahrstedt +3 more
- 19 Apr 2009
TL;DR: This paper proposes a novel signature model - Time Valid One-Time Signature (TV-OTS) - to boost the efficiency of regular one-time signature schemes and designs an efficient multicast authentication scheme "TV-HORS", which provides fast signing/verification and buffering-free data processing.
Cumulative attestation kernels for embedded systems
Michael LeMay,Carl A. Gunter +1 more
- 21 Sep 2009
TL;DR: This paper shows how to implement a CAK in less than one quarter of the memory available on low end AVR32 flash MCUs similar to those used in AMI deployments, and formally proves that remote attestation requirements are met by the implementation even if no battery backup is available to prevent sudden halt conditions.
YASIR: A Low-Latency, High-Integrity Security Retrofit for Legacy SCADA Systems
Patrick P. Tsang,Sean W. Smith +1 more
- 07 Sep 2008
TL;DR: A bump-in-the-wire (BITW) solution that retrofits security into time-critical communications over bandwidth-limited serial links between devices in legacy Supervisory Control and Data Acquisition systems, and yet incurs minimal end-to-end communication latency.

Design Principles for Power Grid Cyber-Infrastructure Authentication Protocols
Himanshu Khurana,Rakesh B. Bobba,Tim Yardley,Pooja Agarwal,Erich Heine +4 more
- 05 Jan 2010
TL;DR: This work builds on past work in the area of principles of authentication in Internet protocols but focuses the discussion on the constraints of the Power Grid; in particular, the need for efficient and highly available systems.
Cumulative Attestation Kernels for Embedded Systems
Michael LeMay,Carl A. Gunter +1 more
TL;DR: This prototype presents the first formal proof that a system is tolerant to power supply interruptions and discusses how to provide cumulative attestation for devices with tighter memory constraints by offloading computation and storage onto a Cumulative Attestation Coprocessor (CAC).
