lsd abac lightweight static and dynamic attributes based access control scheme for secure data access in mobile environment
Local Computer Networks, 2014Co-Authors: Yogachandran Rahulamathavan, Muttukrishnan RajarajanAbstract:Technology advancements in smart mobile devices empower mobile users by enhancing mobility, Customizability and adaptability of computing environments. Mobile devices are now intelligent enough to capture dynamic attributes such as unlock failures, application usage, location and proximity of devices in and around its surrounding environment. Different users will have different set of values for these dynamic attributes. In traditional attribute based access control, users are authenticated to access restricted data using long term static attributes such as password, roles, and physical location. In this paper, in order to allow secure data access in mobile environment, we securely combine both the dynamic and static attributes and develop novel access control technique. Security and performance analyse show that the proposed scheme substantially reduces the computational complexity while enhances the security compare to the conventional schemes.

towards an open architecture model for web and mobile software characteristics and validity properties
Computer Software and Applications Conference, 2014Co-Authors: Bahtijar Vogel, Arianit Kurti, Tommi Mikkonen, Marcelo MilradAbstract:Proprietary software solutions are extensively deployed through multiple platforms including desktop, web and mobile devices. Such systems are in many cases closed, thus making it difficult for software developers to expand and create additional features to these systems. Recent research in the field of web and mobile technologies indicates that open systems are more successful than those based on proprietary technologies. In this paper, we investigate and analyze existing research related to the notion of open architectures. We conducted a literature survey of the state of the art projects and definitions related to this concept. Our efforts have resulted in a refined definition of the term followed by a conceptual model of an open architecture contextualized within the field of web and mobile software. The model primarily relies on four key characteristics, namely flexibility, evolvability, Customizability and extensibility. Furthermore, we present a validation plan based on the GQM approach that further instantiates these characteristics into a set of properties that can serve as metrics.

from architectural requirements towards an open architecture for web and mobile societal applications
International Conference on Software Engineering, 2014Co-Authors: Bahtijar Vogel, Arianit Kurti, Tommi Mikkonen, Marcelo MilradAbstract:This paper reflects on our experiences during the last four years regarding the development of a web & mobile application for sustainable environment. After five development cycles our software application has become robust, flexible, and expandable platform. Inspired from this and the needs identified during this process we report our research towards identifying novel architectural approaches that nourish open data and emerging web standards for developing open societal applications. The efforts resulted in an open architecture approach that relies on a set of key characteristics - flexibility, evolvability, Customizability, and extensibility. Stressing these characteristics refers to the identified needs of using open standards and reducing development time. The results show that an open architecture approach provides the key ingredients in terms of system integration and data interoperability as well as the ability of the software to grow in terms of new services, devices, and subsystems attached to it, primarily due to the use of open source components and open data standards.

characterization of silicone rubber based soft pneumatic actuators
Intelligent Robots and Systems, 2013Co-Authors: Yun Seong Song, Jamie PaikAbstract:Conventional pneumatic actuators have been a popular choice due to their decent force/torque output. Nowadays, new generation of pneumatic actuator made out of highly compliant elastomers, which we call soft pneumatic actuators (SPA), are drawing increasing attention due to their ease of fabrication, high Customizability and innately softness. However, there is no effective method presented to characterize and understand these actuators, such as to measure the force and torque output, range of motion and the speed of actuation. In this work, we present two types of SPAs: bending and rotary actuators. In addition, we have developed two measurement setups to characterize actuators of different geometries. The measured force/torque outputs of different actuators are presented and analyzed. Step responses to certain pressure input are presented and discussed. A simple model is presented to provide physical insight to the observed behavior of the soft actuators. This work provides the basis for designing customized SPAs with application-specific requirements.

Soft robot for gait rehabilitation of spinalized rodents
IEEE International Conference on Intelligent Robots and Systems, 2013Co-Authors: Yun Seong Song, Rubia Van Den Brand, Joachim Von Zitzewitz, Gregoire Courtine, Silvestro Micera, Yi Sun, Jamie PaikAbstract:Soft actuators made of highly elastic polymers allow novel robotic system designs, yet application-specific soft robotic systems are rarely reported. Taking notice of the characteristics of soft pneumatic actuators (SPAs) such as high Customizability and low inherent stiffness, we report in this work the use of soft pneumatic actuators for a biomedical use - the development of a soft robot for rodents, aimed to provide a physical assistance during gait rehabilitation of a spinalized animal. The design requirements to perform this unconventional task are introduced. Customized soft actuators, soft joints and soft couplings for the robot are presented. Live animal experiment was performed to evaluate and show the potential of SPAs for their use in the current and future biomedical applications.
