In this paper, we ļ¬rst introduce a new kind of adversarial goal called forge-and-impersonate in undeniable signature schemes. Note that forgeability does not necessarily imply im...
We introduce a new computational problem related to the interpolation of group homomorphisms which generalizes many famous cryptographic problems including discrete logarithm, Diļ¬...
A fragmentary pattern is a multiset of non-empty strings, and it matches a string w if all the strings in it occur within w without any overlaps. We study some fundamental issues o...

We propose a theoretical framework for speciļ¬cation and analysis of a class of learning problems that arise in open-ended environments that contain multiple, distributed, dynamic...
The lift-and-project closure is the relaxation obtained by computing all lift-and-project cuts from the initial formulation of a mixed integer linear program or equivalently by co...
