“…Beaver et al (2002) present a cryptographic key management algorithm for SCADA systems which uses a combination of symmetric and public keys, the mechanism differs between master-controller and peer-to-peer links. Dawson et al (2006) builds on the work of Beaver et al (2002), by providing both a unified communication technique for master-controller and peer-to-peer connections using only symmetric keys instead of public keys in order to to reduce network traffic load. Choi et al (2009) present a solution to the problem of broadcast communications, to be used in the event of, for example broadcasting alarm states.…”

Industrial Control Systems (ICS) and SCADA (Supervisory Control and Data Acquisition) systems are typically used in industries such as electricity generation and supply, gas supply, logistics, manufacturing and hospitals and are considered critical national infrastructure. The evolution of these systems from isolated environments into internet connected ones, in combination with their long service life and real-time nature have raised severe security concerns in the event of a cyber-attack. In this paper, we review the current literature surrounding the threats, vulnerabilities, exploits and existing approaches to securing vulnerable SCADA systems. We then focus specifically on the development of a distributed online runtime monitor to detect violations of safety properties. We conclude with suggestions for further research needed to progress the state of the art in the area of distributed online runtime verification of SCADA systems.

“…With the integration of the Smart Grid with existing SCADA systems, which have been employed since the '60s, the resulting system should have a unified key management scheme for the secure communication of all components among them. There are quite a few key management schemes designed especially for SCADA: [4,8,6,17,7,12]; however, they are not adequate because they do not take into account the rest of the Smart Grid's components. An overview of each of these proposals is presented in [23].…”

“…Information and communication technology introduction to the traditional power networks will provide advantages like efficiency, increased reliability, resilience, distributed intelligence, and better control of demand response. The EU has plans to replace at least 80% of its electricity meters with smart ones by the year 2020 4 . According to a US report [1], the smart meter installations in the USA have reached 50 million of devices as of July 2014.…”

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.

“…Using of advance information technology with SCADA system is considered and provides solutions to minimized threads/attacks issues within communication (Beaver et al, 2002). The "client puzzles" technique has been uses to detect "SYN flood TCP DOS" within SCADA communication (when attacker again control on master controller resources) and also managed the session requirement within electrical industry uses QOS technique.…”

The SCADA system connectivity with several open networks using internet facility brought SCADA platform more vulnerable from attacks/threads. Therefore, the detail security review has been conducted, to find the potential security issues which are residing and warming the SCADA communication and also existing potential security solutions that are used to protect the SCADA communication. However, Security deployments are the future tread of this study. This security review is divided into four main sections: (1) Security Analysis for SCADA System, (2) SCADA Security using Cryptography Solution, (3) Key Management and Distribution Protocols for SCADA System and (4) SCADA Communication using Security Patterns. In this study; the SCADA security review has been conducted and generic security solution using cryptography will implement in future.
