Network users today have to remember one username/password pair for every service they are registered with. One solution to the security and usability implications of this situation is Single Sign-On, a mechanism by which the user authenticates only once to an entity termed the ‘Authentication Service Provider’ (ASP) and subsequently uses disparate Service Providers (SPs) without necessarily re...
We present the prototyping of a heterogeneous multiprocessor system-on-chip (MPSoC) design, which consists of general purpose RISC processors as well as novel accelerators in form of tightly-coupled processor arrays (TCPA). In general, TCPAs are well suited to accelerate numerous compute-intensive tasks such as video and other digital signal processing. We consider a transactor-based co-design ...
The world's worst cholera epidemic in Haiti (2010) coerced to trace the origin and dissemination of the causative agent Vibrio cholerae O1 for proper management of cholera. Sequence analysis of the Haitian strain showed several variations in the genes encoding cholera toxin B subunit (ctxB); toxin-co-regulated pilus (tcpA), repeat in toxins (rtxA), quinolone resistance-determining region (QRDR)...
In this paper, a method is described for providing a distributed reputation system with enhanced privacy and security as a design feature. This is achieved using a network of trusted agents on each client platform that exploit Trusted Computing Platform Alliance (TCPA) technology [1].
BACKGROUND Vibrio cholerae causes diarrhoeal disease that afflicts thousands of people annually. V. cholerae is classified on the basis of somatic antigens into serovars or serogroups and there are at least 200 known serogroup. Two serogroups, O1 and O139 have been associated with epidemic diseases. Virulence genes of these bacteria are OmpW, ctxA and tcpA. OBJECTIVES Due to the importance of...
The incidence of Vibrio cholerae non-O1, non-O139 strains from hospitalized patients with acute diarrhea constituted 27.4% (n = 54) of the total 197 V. cholerae strains isolated from patients in Kolkata, India, in 2003. Of 197 strains, 135 were identified as O1 serotype Ogawa and 2 were identified as O139. In the same time period, six O1 background rough strains that possessed all known virulen...
In Vibrio cholerae, the transmembrane DNA binding proteins, ToxR and TcpP, activate expression of the regulatory gene toxT in response to specific environmental signals. The resulting enhanced level of ToxT leads to a coordinated increase in the production of a subset of virulence factors, including cholera toxin (CT) and toxin-coregulated pilus (TCP). The effect of anaerobiosis on expression o...
