01 Jan 2012TL;DR: The paper describes the principles of PTIDES, which leverages network time synchronization to provide a determinate distributed real-time semantics and shows how PTIDES can function as a coordination language, orchestrating components that may be designed and specified using different formalisms.
Abstract: Real-time embedded software today is commonly built using programming abstractions with little or no temporal semantics. This paper addresses this problem by presenting a programming model called programming temporally integrated distributed embedded systems (PTIDES) that serves as a coordination language for model-based design of distributed real-time embedded systems. Specifically, the paper describes the principles of PTIDES, which leverages network time synchronization to provide a determinate distributed real-time semantics. We show how PTIDES can function as a coordination language, orchestrating components that may be designed and specified using different formalisms. We show the use of this environment in the design of interesting and practical cyber-physical systems, such as a power plant control system.

TL;DR: Industrial Internet-of-Things hub (IIHub) is proposed, which consists of customized access module (CA-Module), access hub (A-Hub), and local service pool (LSP) and supports manufacturing services online generation based on the service encapsulation templates and also supports quick configuration and implementation for smart interconnection.
Abstract: Smart manufacturing is increasingly becoming the common goal of various national strategies. Smart interconnection is one of the most important issues for implementing smart manufacturing. However, current solutions are not tended to realize smart interconnection in dealing with heterogeneous equipment, quick configuration and implementation, and online service generation. To solve the issues, industrial Internet-of-Things hub (IIHub) is proposed, which consists of customized access module (CA-Module), access hub (A-Hub), and local service pool (LSP). A set of flexible CA-Modules can be configured or programed to connect heterogeneous physical manufacturing resources. Besides, the IIHub supports manufacturing services online generation based on the service encapsulation templates and also supports quick configuration and implementation for smart interconnection. Furthermore, related smart analysis and precise management have the potential to be achieved. Finally, a prototype is given to illustrate the functions of the proposed IIHub, and to show how IIHub realizes smart interconnection.

TL;DR: This paper investigates CCPAs in smart grid and shows that an adversary can carefully synthesize a false data injection attack vector based on phasor measurement unit (PMU) measurements to neutralize the impact of physical attack vector, such that CCPAs could circumvent bad data detection without being detected.
Abstract: Smart grid, as one of the most critical infrastructures, is vulnerable to a wide variety of cyber and/or physical attacks. Recently, a new category of threats to smart grid, named coordinated cyber-physical attacks (CCPAs), are emerging. A key feature of CCPAs is to leverage cyber attacks to mask physical attacks which can cause power outages and potentially trigger cascading failures. In this paper, we investigate CCPAs in smart grid and show that an adversary can carefully synthesize a false data injection attack vector based on phasor measurement unit (PMU) measurements to neutralize the impact of physical attack vector, such that CCPAs could circumvent bad data detection without being detected. Specifically, we present two potential CCPAs, namely replay and optimized CCPAs, respectively, and analyze the adversary’s required capability to construct them. Based on the analytical results, countermeasures are proposed to detect the two kinds of CCPAs, through known-secure PMU measurement verification (in the cyber space) and online tracking of the power system equivalent impedance (in the physical space), respectively. The implementation of CCPAs in smart grid and the effectiveness of countermeasures are demonstrated by using an illustrative 4-bus power system and the IEEE 9-bus, 14-bus, 30-bus, 118-bus, and 300-bus test power systems.
