Secure two-party protocols are of significant research and application value. All-or-Nothing Disclosure of Secrets (ANDOS) is such a kind of cryptographic task. It involves two parties, a vendor and a buyer. The vendor, say Alice, who disposes of several secrets and is willing to sell any of them to the buyer, say Bob, with the guarantee that no information about the other secrets will be obtai...

A vendor has several secrets which he regards as of equal worth and importance. He is willing to sell any of these secrets to a buyer. The bargain is said to be secure when the following two conditions are satisfied: 1) the buyer can only obtain one secret if he pays for only one secret, and 2) the vendor will not be able to find out which secret the buyer picked. This cryptographic problem is ...

Two-party protocols have been considered for a long time. Currently, there is a renewed effort to revisit specific protocols to gain efficiency. As an example, one may quote the breakthrough of [BF97], bringing a new solution to the problem of secretly generating RSA keys, which itself goes back to the pioneering work by Yao [Yao86]. The AllOr-Nothing Disclosure of Secrets protocol (ANDOS) was ...

in this paper, two pairs of new inequalities are given, which decompose two hilbert-type inequalities.

we derive whole series of new integral inequalities of the hardy-type, with non-conjugate exponents. first, we prove and discuss two equivalent general inequa-li-ties of such type, as well as their corresponding reverse inequalities. general results are then applied to special hardy-type kernel and power weights. also, some estimates of weight functions and constant factors are obtained. ...

in order to estimate the effects of the macrc~econornic indicators on the income distribution of iran, the time series data during the period of 1971-1991 were used. first the yammetric inequality indicators (the gini coefficients) were estimated for the years 1991-1972. the results show the lowest level of inequality in 1980 with g=0.42 and the highest level in 1982 with g=0.55. arzulysing the...
