    Cache contention modeling is necessary for good resource utilization on commercial multicore processors. Our goal is to build cache contention models that are sensitive to changes in, 1) the micro-architecture, 2) ...
  • Chang, Donghoon; Ghosh, Mohona; Sanadhya, Somitra Kumar (2015-03-23)
    In this work, we revisit the security analysis of AES-128 instantiated hash modes. We use biclique cryptanalysis technique as our basis for the attack. The traditional biclique approach used for key recovery in AES (and ...
  • Goyal, Vikram; Dawar, Siddharth (2015-02-11)
    High-utility itemset mining is an emerging research area in the field of Data Mining. Several algorithms were proposed to find high- utility itemsets from transaction databases and use a data structure called UP-tree ...
  • Sankaran, Anush; Vatsa, Mayank; Singh, Richa (2015-01-27)
    Latent fingerprint comparison evidences are used in the court of law for more than 100 years. Manual matching of latent fingerprints is challenged by subjectivity and inconsistency in terms of results and is not scalable ...

    Network censorship and surveillance generally involves ISPs working under the orders of repressive regimes, monitoring (and sometimes filtering) users’ traffic, often using powerful networking devices, e.g. routers ...
  • Verma, Robin; Gupta, Gaurav (2014-12-25)
    The use of digital technology in conventional as well as new age crimes is increasing throughout the world, and researchers are working to develop digital forensics techniques to investigate such crimes. Digital forensic ...

    Sleep quantity affects an individual’s personal health. The gold standard of measuring sleep and diagnosing sleep disorders is Polysomnography (PSG). Although PSG is accurate, it is expensive and it lacks portability. ...
  • Hemani, Rakhi; Banerjee, Subhasis; Guha, Apala (2014-09-15)
    Simultaneous execution of multiple threads on multicores is necessary for good resource utilization. However, such utilization calls for accurate models to predict the impact on performance due to contention of shared ...
  • Mishra, Shreemoy (2014-07-16)
    I study the market for consumer information. Firms cannot commit to privacy, so buyers anticipate disclosure of purchase history for targeted pricing. In the literature, strategic rejections of informative o ers make ...

    For robust face biometrics, a reliable anti-spoofing approach has become an essential pre-requisite against attacks. While spoofing attacks are possible with any biometric modality, face spoofing attacks are relatively ...
  • Asthana, Siddhartha; Singh, Pushpendra (2014-04-28)
    Dialing a telephone number of an organization and coming across an automated system attending the call, instead of a human, has become common. These automated applications are known as Interactive Voice Response (IVR) ...
