A scheme for general group oriented ID-based cryptosystems is proposed. This scheme allows an authorized subset in the general access structure to cooperatively decrypt the cipher...
We give a (1 - 1/e)-approximation algorithm for the Max-Profit Generalized Assignment Problem (Max-GAP) with fixed profits when the profit (but not necessarily the size) of every ...
This paper reports on an approach to model generalized implicatures using nonmonotonic logics. The approach, called compositional, is based on the idea of compositional semantics, ...
ally related entity types, or classes, into higher level, more abstract types, as part of a hierarchical classi®cation scheme. graphy, generalization retains the notion of abstrac...
—The generalized cyclotomic sequence of order two has several good randomness properties and behaves like the Legendre sequence in several aspects. In this correspondence we calc...
