“…In addition, the communication between the publisher and the subscriber is achieved asynchronously because the subscriber does not have to be in a blocked waiting state for an event to arrive, but rather, it is able to carry-out concurrent operations. In the actual implementation of the publisher-subscriber communication model in IEC 61850 environment, taking GOOSE message communication as an instance; the publishing IED writes the values into a local buffer at the sending side, which is then multi-cast; while the subscribing IED(s) reads the values from a local buffer at the receiving side [9]. The communication channel is saddled with the task of updating the local buffers of the subscribers.…”

Adversarial models are well-established for cryptographic protocols, but distributed real-time protocols have requirements that these abstractions are not intended to cover. The IEEE/IEC 61850 standard for communication networks and systems for power utility automation in particular not only requires distributed processing, but in case of the generic object oriented substation events and sampled value (GOOSE/SV) protocols also hard real-time characteristics. This motivates the desire to include both quality of service (QoS) and explicit network topology in an adversary model based on a π-calculus process algebraic formalism based on earlier work. This allows reasoning over process states, placement of adversarial entities and communication behaviour. We demonstrate the use of our model for the simple case of a replay attack against the publish/subscribe GOOSE/SV subprotocol, showing bounds for non-detectability of such an attack.Index Terms-Adversary model, Quality of services, IEC 61850, Real-time communication protocols I. INTRODUCTIONReal-time communication protocols are among the most prominent communication protocols used in networked critical infrastructures. They are used to monitor and control industrial automation processes deployed in critical infrastructures including power stations, power and water distribution, and traffic systems. The resilience of networked critical infrastructures is depended on the ability of the communication protocols used in such environments to adapt well in the face adversarial actions.Adversary model describes the capabilities of an attacker [1] and facilitates reasoning about how a system may be compromised. The conventional adversary models are not suitable for capturing the capabilities of an attacker in IEC 61850 environment due to the stringent QoS requirements and the network topology [2]. Also, the conventional adversary models do not consider the network topology of IEC 61850 because they assume that there is a point-to-point communication between all parties. Thus, it is important to develop an adversary model which takes into account the constraints imposed on an attacker with the intention of attacking the IEC 61850 real-time communication protocols.We therefore propose an adversary model for IEC 61850 real-time communication protocols in this paper. First, we use IEC 61850 GOOSE messaging service as an example, and derive its formalization using π−calculus variant. We then show that the relative positions of the adversary in relation to the publisher, event notification service, and subscriber determine the type of attacks that can be launched by an attacker. Lastly, we use our model to describe a reply attack that can result in a denial of service (DoS) attack.The rest of this paper is organized as follows. Section II presents a general discussion on real-time communication protocols and introduces the π−calculus syntax. Section III discusses the related works. Section IV describes the adversary model and its formalization using π−calculus variant. Section V pr...

“…Suppose fault occurs on line 3-4, according to the algorithm in Section 2.2.1, the correlated breaker sequence is T = (0, 0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0) T , that is, breakers CB [3][4] and CB . After the area main computer issues the tripping command at t = 0.4 s, the current through breaker CB 4-3 is still bigger than δ; thus breaker CB 4-3 fails and the breaker failure algorithm is needed.…”

Summary The development of large inter‐connected power grid poses an urgent need for better adaptability of the backup protection. In this paper, a wide area backup protection tripping strategy based on directional weighting is proposed, on the premise that the fault component has been identified by the limited wide area centralized backup protection. First, according to the network topology and the positive sequence current phasor information of the switches in local area, the node–branch correlation matrix based on directional weighting is formed. And then, based on the fault identification result and the positive sequence current phasor information of the switches, the component–breaker correlation degree vector is constructed, and the correlated breakers are identified and tripped. Simulation results verify that, with the proposed method, the backup protection coordination is simplified and fault clearance could be limited to the minimum range in various cases. Meanwhile, the proposed method is applicable and reliable even when part of the information is missing, and the requirement on information synchronization is not strict.
