    FlexList: Optimized Skip List for Secure Cloud Storage

    With the increase in popularity of cloud data storage, efficiently proving the integrity of the data stored at an untrusted server has become significant. Authenticated Skip Lists and Rank-based Authenticated Skip Lists (RBASL) have been used in cloud storage as a randomized alternative to balanced trees, without the need to...

    Energy Efficiency in Secure and Dynamic Cloud Storage

    The popularity of the cloud storage systems has brought a number of challenges. Two of them are data integrity and energy efficiency. There are many proposed static solutions to prove the integrity of a file. For the dynamic case, Rank-Based Authenticated Skip List (RBASL) has been presented. It provides the...

    Dynamic Proofs of Retrievability via Oblivious RAM

    Proofs of retrievability allow a client to store their data on a remote server (e.g., "in the cloud") and periodically execute an efficient audit protocol to check that all of the data is being maintained correctly and can be recovered from the server. For efficiency, the computation and communication of...

    Ultra - Wideband Channel Model for Intra-Vehicular Wireless Sensor Networks

    Intra-vehicular wireless sensor networks is a promising new research area that can provide part cost, assembly, maintenance savings and fuel efficiency through the elimination of the wires, and enable new sensor technologies to be integrated into vehicles, which would otherwise be impossible using wired means, such as Intelligent Tire. The...

    Official Arbitration and Its Application to Secure Cloud Storage

    Many cryptographic protocols exist that enable two parties to exchange items (e.g., e-commerce) or agree on something (e.g., contract-signing). In such settings, disputes may arise. Official arbitration refers to the process of resolving disputes between two (or more) parties by a trusted and authorized Judge, based on evidence provided. As...

    The Dependence Of Health Insurance Availability On Years Left Before Medicare

    The authors study the dependence of health insurance availability of near-elderly inpatients in the United States with respect to their ages. They show that the likelihood that near-elderly inpatients are uninsured continuously declines until the early ages of 60 but the trend is reversed for the last few years preceding...

    Rate Control for Gop-Level Rate Adaptation in H.264 Video Coding

    It may be desirable to adapt the coding bitrate according to both bandwidth availability and user preferences in video transmission over packet networks. Classical approaches for rate adaptation has been bitstream switching, which requires storing several pre-coded versions of the same video at different bitrates, or layered (scalable) video coding,...

    Deciding To Decide: Gender, Leadership And Risk-Taking In Groups

    Being the leader in a group often involves making risky decisions that affect the payoffs of all members, and the decision to take this responsibility in a group is endogenous in many contexts. In this paper, the authors experimentally study: the willingness of men and women to make risky decisions...

    Bio-Inspired Networking: From Theory to Practice

    Bio-inspired networking techniques have been investigated since more than a decade. Findings in this field have fostered new developments in networking, especially in the most challenging domains such as handling large scale networks, their dynamic nature, resource constraints, heterogeneity, unattended operation, and robustness. Even though this new research area started...

    ProFID: Practical Frequent Item Set Discovery in Peer-to-Peer Networks

    This paper addresses the problem of discovering frequent items in unstructured P2P networks. This problem is relevant for several distributed services such as cache management, data replication, sensor networks and security. The authors make three contributions to the current state of the art. First, they propose a fully distributed Protocol...

    The Effects Of Social Security Taxes And Minimum Wages On Employment: Evidence From Turkey

    Using worker-level panel data for Turkey, this paper analyses the separate employment effects of increases in the social security taxes paid by employers and increases in the minimum wage between 2002 and 2005. Variation over time and among low-wage workers in the ratio of total labour costs to the gross...
