  • Design and Control of a Redundant Suspended Cable-Driven Parallel Robots
    2012
    Co-Authors: Johann Lamaury, Marc Gouttefarde, Micaël Michelin, Olivier Tempier
    Abstract:

    This paper introduces a six degree-of-freedom suspended parallel robot driven by eight cables. The determination of an optimal geometry of such a parallel cable robot together with the design of a prototype are briefly outlined. Then, based on usual kinematic modeling, a basic control strategy is presented. Since the parallel cable-driven robot presented here is redundantly actuated, this control strategy has to deal with the problem of cable tension distribution. This latter turns out to be challenging because of the under-Constrained Nature of the considered cabledriven robot. The extension to these robots of existing tension distribution methods is finally discussed.

  • Quality-aware resource management for wireless sensor networks
    Lecture Notes in Computer Science, 2006
    Co-Authors: Roland Gemesi, Nirvana Meratnia, Paul J.m. Havinga
    Abstract:

    Due to the distributed and resource Constrained Nature of wireless sensor networks, their design proves to be difficult. We present a resource management framework, which integrates a data-centric lightweight operating system with a publish/subscribe middleware. In this framework, the main system abstraction is data for both local and networked processing. The resultant system software is extended with a quality-aware adaptation mechanism, which configures system timeliness according to the actual application requirements. A feedback-based control mechanism is used to iteratively tune the resultant data granularity in order to fit user requirements. Our design is evaluated by simulations and the concepts were also implemented in our sensor network testbed.

  • Efficient Security and Privacy Protection for Emerging Smart RFID Communications
    International Journal of Networked and Distributed Computing, 2014
    Co-Authors: Mohammad Fal Sadikin, Marcel Kyas
    Abstract:

    Due to its Constrained Nature, the use of smart RFID technology introduces tremendous security and privacy issues. This paper presents IMAKA-Tate: Identity protection, Mutual Authentication and Key Agreement using Tate pairing of Identity-based Encryption method. It is designed to tackle various challenges in the Constrained Nature of RFID applications by applying a light-weight cryptographic method with advanced-level 128 bit security protection. Thus, IMAKA-Tate protects the RFID system from various security and privacy threats (e.g. unauthorized tracking, cloning attack, etc.).

  • SNPD - Security and privacy protocol for emerging smart RFID applications
    15th IEEE ACIS International Conference on Software Engineering Artificial Intelligence Networking and Parallel Distributed Computing (SNPD), 2014
    Co-Authors: Mohammad Fal Sadikin, Marcel Kyas
    Abstract:

    The raise of smart RFID technology (i.e. sensor integration to RFID system) has introduced various advantages in the context of location awareness applications, reaching from low cost implementation and maintenance, to its flexibility to support large-scale system. Nevertheless, the use of such technology introduces tremendous security and privacy issues (e.g. unauthorized tracking, information leakage, cloning attack, data manipulation, collision attack, replay attack, Denial-of-Service, etc.). On the other hand, the Constrained Nature of RFID application makes the security enforcement is more complicated. This paper presents IMAKA-Tate: Identity protection, Mutual Authentication and Key Agreement using Tate pairing of Identity-based Encryption method. It is designed to tackle various challenges in the Constrained Nature of RFID applications by applying a light-weight cryptographic method with advanced-level 128 bit security protection. Indeed, our proposed solution protects the RFID system from various threats, as well as preserves the privacy by early performing encryption including the identity even before the authentication is started.

  • IISA - RFID-tate: Efficient security and privacy protection for active RFID over IEEE 802.15.4
    IISA 2014 The 5th International Conference on Information Intelligence Systems and Applications, 2014
    Co-Authors: Mohammad Fal Sadikin, Marcel Kyas
    Abstract:

    The emerging active RFID technology over low-rate wireless IEEE 802.15.4 has become promising standard for large-scale tracking applications. Nevertheless, using of such technology introduces tremendous problems in security and privacy. By taking in to account, the Nature of common RFID communication is not mutually authenticated, the RFID system is susceptible from various threats ranging from impersonation, spoofing or data manipulation, to various techniques of man-in-the-middle attacks including denial-of-service and replay attack. In addition, the Nature of RFID tag basically can be read without authorization. Such issue makes the RFID system is highly susceptible to privacy threats (e.g. unauthorized tracking, spying, crucial information leakage, etc.). On the other hand, the Constrained Nature of RFID system makes the security enforcement is more complicated. Indeed, common security and privacy solution, such as using Transport Layer Security method (TLS/SSL) is not feasible for the RFID tag which associates to limited resources. This paper presents RFID-Tate, an efficient privacy protection and mutual authentication using Tate pairing of Identity-based Encryption method. It is tailored to tackle various security and privacy challenges by applying a light-weight cryptographic method with advanced-level 128 bit security protection. In addition, the RFID-Tate maintains the computation overhead as optimally minimum. Thus it is feasible to be implemented in the Constrained Nature of RFID system.
