The round complexity of verifiable secret sharing (VSS) schemes has been studied extensively for threshold adversaries. In particular, Fitzi et al. showed an efficient 3-round VSS for n ≥ 3t+1 [4], where an infinitely powerful adversary can corrupt t (or less) parties out of n parties. This paper shows that for non-threshold adversaries, 1. Two round VSS is possible iff the underlying adversary...

INTRODUCTION Reliable characterization of a hypertrophic scar (HTS) is integral to epidemiologic studies designed to identify clinical and genetic risk factors for HTS. The Vancouver Scar Scale (VSS) has been widely used for this purpose; however, no publication has defined what score on this scale corresponds to a clinical diagnosis of HTS. METHODS In a survey of 1000 burn care providers, we...

In this paper, a method is proposed to construct a visual secret sharing (VSS) scheme for multiple secret images in which each share can be rotated with 180 degrees in decryption. The proposed VSS scheme can encrypt more number of secret images compared with the normal VSS schemes. Furthermore, the proposed technique can be applied to the VSS scheme that allows to turn over some shares in decry...

This paper presents a new Variable Step-Size Normalized Subband Adaptive Filter (VSS-NSAF) algorithm. The proposed algorithm uses the prior knowledge of the system impulse response statistics and the optimal step-size vector is obtained by minimizing the Mean-Square Deviation (MSD). In comparison with NSAF, the VSS-NSAF algorithm has faster convergence speed and lower MSD. To reduce the computa...

The visual secret sharing (VSS for short) scheme is a secret image sharing scheme. A secret image is visually revealed from overlapping shadow images without additional computations. However, the contrast of reconstructed image is much lost. By means of the reversing operation (reverse black and white), Viet and Kurosawa used the traditional VSS scheme to design a VSS scheme which the secret im...

HYPOTHESIS The severity of hearing loss (HL) associated with vestibular schwannomas (VSs) is influenced by genes expressed by the VSs. BACKGROUND Hearing loss is the most common presenting symptoms in patients with VSs, yet its pathophysiology remains elusive. Previous studies have suggested that VSs cause HL not only by inducing degeneration of the auditory nerve by compression but also by p...

In this feature paper, we introduce voluntary sustainability standards (VSS) and canvas the research that has been conducted on VSS from different academic disciplines. We identify four main areas of explore them. First, focus institutional design VSS, which highlights diversity among VSS. Next, studies try to assess impact key dimensions. Third, zoom in analyse uptake or adoption Finally, inte...

The task of reliable classification is to determine if a particular instance classification is reliable. There exist two approaches to the task: the Bayesian framework [3] and the typicalness framework [5]. Although both frameworks are useful, the Bayesian framework can be misleading and the typicalness framework is classifier dependent. To overcome these problems we argue to use version spaces...

BACKGROUND The aim of the study was to examine the psychometric properties of the Vertigo symptom scale - short form (VSS-SF), a condition-specific measure of dizziness, following translation of the scale into Norwegian. METHODS A cross-sectional survey design was used to examine the factor structure, internal consistency and discriminative ability (sample I, n = 503). A cross-sectional pre-i...
