Using augmented reality for supporting information exchange in teams from the Security Domain
Security Informatics, 2015Co-Authors: Dragos Datcu, Heide Lukosch, Stephan Lukosch, Marina CidotaAbstract:The performance of operational teams in the Security Domain relies on quick and adequate exchange of context-related information. Currently, this information exchange is mainly based on oral communication. This paper reports on different scenarios from the Security Domain in which augmented reality (AR) techniques are used to support such information exchange. The scenarios have been elicited using an end-user centred design approach. To support these scenarios, an AR environment has been developed and the usability of the AR support has been evaluated with experts from different operational units in the Security Domain. The first evaluation shows that the scenarios are well defined and the AR environment can successfully support information exchange in teams operating in the Security Domain.

Providing Information on the Spot: Using Augmented Reality for Situational Awareness in the Security Domain
Computer Supported Cooperative Work (CSCW), 2015Co-Authors: Stephan Lukosch, Heide Lukosch, Dragos Datcu, Marina CidotaAbstract:For operational units in the Security Domain that work together in teams, it is important to quickly and adequately exchange context-related information to ensure well-working collaboration. Currently, most information exchange is based on oral communication. This paper reports on different scenarios from the Security Domain in which augmented reality (AR) techniques are used to support such information exchange. The scenarios have been designed with a User Centred Design approach, in order to make the scenarios as realistic as possible. To support these scenarios, an AR system has been developed and evaluated in two rounds. In the first round, the usability and feasibility of the AR support has been evaluated with experts from different operational units in the Security Domain. The second evaluation round then focussed on the effect of AR on collaboration and situational awareness within the expert teams. With regard to the usability and feasibility of AR, the evaluation shows that the scenarios are well defined and the AR system can successfully support information exchange in teams operating in the Security Domain. The second evaluation round showed that AR can especially improve the situational awareness of remote colleagues not physically present at a scene.

CHI Extended Abstracts - On the Spot Information in Augmented Reality for Teams in the Security Domain
Proceedings of the 33rd Annual ACM Conference Extended Abstracts on Human Factors in Computing Systems - CHI EA '15, 2015Co-Authors: Stephan Lukosch, Heide Lukosch, Dragos Datcu, Marina CidotaAbstract:For operational teams in the Security Domain it is important to quickly and adequately exchange context-related information. This is necessary to develop distributed situational awareness and facilitate collaboration. Currently, information exchange is mainly based on oral communication. Oral communication can be misunderstood or ambiguous. This paper reports on different scenarios from the Security Domain in which augmented reality (AR) techniques are used to support information exchange. A combination of quantitative and qualitative evaluation showed that AR can improve the distributed situational awareness of a team.

Critical Infrastructure Protection - MULTIPLE Security Domain MODEL OF A VEHICLE IN AN AUTOMATED PLATOON
Critical Infrastructure Protection XI, 2017Co-Authors: Uday Kanteti, Bruce M. McmillinAbstract:This chapter focuses on the Security of automated vehicle platoons. Specifically, it examines the vulnerabilities that occur via disruptions of the information flows among the different types of sensors, the communications network and the control unit in each vehicle of a platoon. Multiple Security Domain nondeducibility is employed to determine whether or not the system can detect attacks. The information flows among the various Domains provide insights into the vulnerabilities that exist in the system and whether the model is nondeducible. If nondeducibility is found to be true, then an attacker can create an undetectable attack. Defeating nondeducibility requires additional information sources, including invariants pertaining to vehicle platoon operation. A platoon is examined from the control unit perspective to determine if the vulnerabilities are associated with preventing situational awareness, which could lead to vehicle crashes.

Multiple Security Domain nondeducibility for point-of-care diagnostic technology: WiP abstract
2016Co-Authors: Fred Love, Bruce M. Mcmillin, Sivanesan Tulasidas, Wamadeva BalachandranAbstract:Microfluidics is an interdisciplinary science focusing on the development of devices and systems that process low volumes of fluid for applications such as high throughput DNA sequencing, immunoassays, and entire Labs-on-Chip platforms. Microfluidic diagnostic technology enables these advances by facilitating the miniaturization and integration of complex biochemical processing through a microfluidic biochip [1]. This approach tightly couples the biochemical operations, sensing system, control algorithm, and droplet-based biochip. During the process the status of a droplet is monitored in real-time to detect operational errors. If an error has occurred, the control algorithm dynamically reconfigures to allow recovery and rescheduling of on-chip operations. During this recovery procedure the droplet that is the source of the error is discarded to prevent the propagation of the error and the operation is repeated. Threats to the operation of the microfluidics biochip include (1) integrity: an attack can modify control electrodes to corrupt the diagnosis, and (2) privacy: what can a user/operator deduce about the diagnosis? It is challenging to describe both these aspects using existing models; as Figure 1 depicts there are multiple Security Domains, Unidirectional information flows shown in black indicate undesirable flows, the bidirectional black arrows indicate desirable, but possibly corrupted, information flows, and the unidirectional red arrows indicate undesirable information flows. As with Stuxnet, a bidirectional, deducible information flow is needed between the monitoring Security Domain and internal Security Domain (biochip) [2]. Simultaneously, the attacker and the operators should receive a nondeducible information flow. Likewise, the red attack arrows should be deducible to the internal Domain. Our current Security research direction uses the novel approach of Multiple Security Domain Nondeducibility [2] to explore the vulnerabilities of exploiting this error recovery process through information flow leakages and leads to protection of the system through desirable information flows.

a multiple Security Domain model of a drive by wire system
Computer Software and Applications Conference, 2013Co-Authors: Gerry Howser, Bruce M. McmillinAbstract:Traditional Security models partition the Security universe into two distinct and completely separate worlds: us and them. This partition is absolute and complete. More complex situations are most commonly treated as sets of increasingly more secure Domains. This view is too simplistic for cyber-physical systems. Absolute divisions are conceptually clean, but they do not reflect the real world. Security partitions often overlap, frequently provide for the high level to have complete access to the low level, and are more complex than an impervious wall. We present a model that handles situations where the Security Domains are complex or the threat space is ill defined. To demonstrate our method, we examine a 'drive by wire' system from both the traditional view and in light of the modern reality. This paper examines the system from the viewpoint of the driver with special emphasis on the driver's inability to determine who, or what, is actually in control of the automobile during critical situations.
