Packet-Hiding Methods for Preventing Selective Jamming Attacks

Dependable and Secure Computing IEEE 2012- January- February 2012 Technology Used: JAVA The open nature of the wireless medium leaves it vulnerable to intentional interference attacks, typically referred to as jamming. This intentional interference with wireless transmissions can be used as a launchpad for mounting Denial-of-Service attacks on wireless networks. Typically, jamming has been addressed [...]

pCloud: A Distributed System for Practical PIR

Dependable and Secure Computing – IEEE 2012 – January- February 2012 Technology Used: Java/J2EE Computational Private Information Retrieval (cPIR) protocols allow a client to retrieve one bit from a database, without the server inferring any information about the queried bit. These protocols are too costly in practice because they invoke complex arithmetic operations for every [...]

Multiple Exposure Fusion for High Dynamic Range Image Acquisition

Image Processing – IEEE 2012- January 2012 Technology Used: DOT NET A multiple exposure fusion to enhance the dynamic range of an image is proposed. The construction of high dynamic range images (HDRIs) is performed by combining multiple images taken with different exposures and estimating the irradiance value for each pixel. This is a common [...]

Pareto-Based Dominant Graph: An Efficient Indexing Structure To Answer Top-K Queries

Technology Used: Dot Net Knowledge and Data Engineering, IEEE 2011 Given a record set D and a query score function F, a top-k query returns k records from D, whose values of function F on their attributes are the highest. In this paper, we investigate the intrinsic connection between top-k queries and dominant relationships between [...]
