This paper describes an efficient (k, n) threshold digital signature scheme. In the scheme, k out of n signers cooperate to issue a signature without using trusted center. No secret communication is required among signers across the network. As a base scheme, Pedersen's verifiable secret sharing (VSS) is applied to generate shared secret keys in such a way that no secret communication is requir...

A publicly verifiable secret sharing (PVSS) scheme is a verifiable secret sharing (VSS) scheme in which anyone, not only the shareholders, can verify that the secret shares are correctly distributed. PVSS plays an essential role in the systems that use VSS. In this paper we present a new construction for PVSS scheme based on Paillier encryption scheme.We formalize the notion of indistinguishabi...

N ature interpretation centers are a romantic expression of the desire to understand and experience nature without giving up the comforts of civilization. Advances in digital technologies let us collect and store masses of data about our natural environment, but we are more removed from it than ever. As a society, we find ourselves trading experience-based knowledge for comfort. Interpretation ...

Kieran Ferris / Liam Bannon Interaction Design Centre University of Limerick Ireland [email protected] [email protected] Abstract The Cardboard Box Garden (CBG) originated from a shared dissatisfaction with current computer technology as it is presented to children. This paper shall briefly review the process involved in the creation of this installation, from motivation through to design and...

Introduction The overall health status of workers of tea garden of Bangladesh is below the national standard. Also, almost nothing has been reported about status of hepatitis virus infection among these population and there is also a lack of consensus. Materials and methods Several health-related facts, especially those of liver diseases, were collected from 130 workers of tea garden via ques...

A botanic garden is essentially a museum of living plants. The word 'museum' is derived from the name of the Greek goddesses of learning and the arts; thus a museum is a place devoted to the pursuit of such studies. A botanic garden is primarily a place where plants are grown for scientific study. But a garden differs from a museum in the fact that the objects in it are living and growing, and ...

In this paper, we introduce a method of threshold secret sharing scheme (TSSS) in which secret reconstruction is based on Babai's nearest plane algorithm. In order to supply secure public channels for transmitting shares to parties, we need to ensure that there are no quantum threats to these channels. A solution to this problem can be utilization of lattice-based cryptosystems for these channe...

Uniform randomness beacons whose output can be publicly attested to be unbiased are required in several cryptographic protocols. A common approach to building such beacons is having a number parties run a coin tossing protocol with guaranteed output delivery (so that adversaries cannot simply keep honest parties from obtaining randomness, consequently halting protocols that rely on it). However...

BACKGROUND Schools face increasing demands to provide education on healthy living and improve core academic performance. Although these appear to be competing concerns, they may interact beneficially. This article focuses on school garden programs and their effects on students' academic and dietary outcomes. METHODS Database searches in CABI, Web of Science, Web of Knowledge, PubMed, Educatio...

AIMS To test the relationship between greenery in gardens at residential facilities for older people and the self-perceived health of residents, mediated by experiences of being away and fascination when in the garden and the frequency of visitation there. To examine how these indirect effects vary with the number of physical barriers to visiting the garden. BACKGROUND Many older people in re...
