In this paper we are interested in efficient and secure constant round multi-party protocols which provide unconditional security against so called honest-but-curious adversaries. In particular, we design a novel constant round protocol that converts from shares over Zq to shares over the integers working for all shared inputs from Zq. Furthermore, we present a constant round protocol to secure...

E-voting systems (EVS)are having potential advantages over many existing voting schemes. Security, transparency, accuracy and reliability are the major concern in these systems. EVS continues to grow as the technology advances. It is inexpensive and efficient as the resources become reusable. Fast and accurate computation of results with voter privacy is the added advantage. In the proposed sys...

Visual cryptography is a popular solution for image encryption. The encryption procedure encrypts a image into the so-called shares which are noise-like secure images which can be transmitted or distributed over an untrusted communication channel. Using the properties of the human visual system to force the recognition of a secret message from overlapping shares, the image is decrypted without ...

this paper applied a non-parametric (data envelopment analysis) method to analyze the efficiency of farmers, discriminate efficient farmers from inefficient ones and to identify wasteful uses of energy in order to optimize the energy inputs for greenhouse cucumber production in lorestan province of iran. data were collected from 27 cucumber producers by using a face-to-face questionnaire.dea cr...

In this paper apprized three paradigms for visual cryptography for TAMIL Characters, wherein k out of n shares is sufficient to see the confidential information. Visual and polynomial-based are the two major categories in cryptography. This paper incorporates both simple and composite models to accomplish secret sharing. Secret data is sent to the holders as shares but how they decrypt the shar...

in iran, more than 96.4 percent of dairy farms (including more than 68.7 percent of cattle and calf) have a less than 20 heads of animals, and they produce more than two-thirds of milk and most of animal protein. also, large shares of water, land and labor force resources are used by this production section. less scientific studies have been focused on this production system despite it's m...

development in the production of agricultural products can take place in two ways: 1) increasing the inputs, which due to limitations in resources is possible only up to a specified level. the second possibility is to increase the productivity of the units by making use of new technologies. technology is defined as, substituting new ways of production for the old ones to increase production per...

The present study examines the impact of capital employed in buyback of shares on firm value for 180 firms listed in the Bombay Stock Exchange of India. The issue of buyback of shares in the period from 2006 to 2016 was examined. The firm value is measured by a proxy, enterprise value, as a substitute of share price. The results suggest that the firm value differs from pre and post buyback of s...

The Federal Court of Appeal recently rendered its judgment in Citibank15 and affirmed the Tax Court of Canada’s earlier decision.16 The issue in Citibank was whether certain shares constituted “term preferred shares,” as defined in subsection 248(1) of the Act. Where a specified financial institution (SFI) acquires term preferred shares in the ordinary course of business, subsection 112(2.1) of...
