Most previous work on unconditionally secure multiparty computation has focused on computing over a nite eld (or ring). Multiparty computation over other algebraic structures has not received much attention, but is an interesting topic whose study may provide new and improved tools for certain applications. At CRYPTO 2007, Desmedt et al introduced a construction for a passive-secure multiparty ...

For searchable symmetric encryption schemes (or symmetrickey encryption with keyword search), the security against passive adversaries (i.e. privacy) has been mainly considered so far. In this paper, we first define its security against active adversaries (i.e. reliability as well as privacy). We next formulate its UC-security. We then prove that the UCsecurity against non-adaptive adversaries ...

This article presents a new current-mode multiplier/divider based on MO-CDTA (Multiple output current conveyor transconductance amplifier). The circuit description is very simple, its construction consists of only one MO-CDTA. Without external passive elements, the proposed circuit is then suitable for IC architecture. The PSpice simulation and experimental results are depicted, and agree well ...

Sign languages (SL) require a fundamental rethinking of many basic assumptions about human language processing because instead of using linear speech, sign languages coarticulate facial expressions, shoulder and hand movements, eye gaze and usage of a three-dimensional space. SL researchers have therefore advocated SL-specific approaches that do not start from the biases of models that were ori...

Construction Grammar has reached a stage of maturity where many researchers are looking for an explicit formal grounding of their work. Recently, there have been exciting developments to cater for this demand, most notably in Sign-Based Construction Grammar (SBCG) and Fluid Construction Grammar (FCG). Unfortunately, like playing a music instrument, the formalisms used by SBCG and FCG take time ...

Our keynote lecture will be given by Dr. Steven Stanhope, director of the Physical Disabilities Branch at the National Institutes of Health. Dr. Stanhope will discuss findings from a series of research projects related to customization and selective laser sintering construction of passive dynamic ankle-foot orthoses to meet a patient’s individual needs and the biomechanical basis for adapted co...

In this paper, we present a variant of Waters’ Identity-Based Encryption scheme with a much smaller public-key size (only a few kilobytes). We show that this variant is semantically secure against passive adversaries in the standard model. In essence, the new scheme divides Waters’ public key size by a factor ` at the cost of (negligibly) reducing security by ` bits. Therefore, our construction...

The labor-intensive nature of the construction industry requires workers to frequently perform physically demanding manual work, thereby exposing them risk musculoskeletal injury (approximately 31.2 cases per 10,000 full-time equivalent workers). Exoskeletons and exosuits (collectively called EXOs here) are designed protect from these injuries by reducing exertion muscle fatigue during work. Ho...
