A long-standing goal of software engineering is to construct software that is easily modified and extended. Recent advances in software design techniques, such as aspect-oriented ...
Chameleon signatures were introduced by Krawczyk and Rabin, being non-interactive signature schemes that provide non-transferability. However, that first construction employs a c...
We consider the problem of constructing a general protocol for secure two-party computation in a way that preserves security under concurrent composition. In our treatment, we foc...
Abstract. We present an asymptotically optimal reduction of one-outof-two String Oblivious Transfer to one-out-of-two Bit Oblivious Transfer using Interactive Hashing in conjunctio...
he correspondence between the role abstraction in Role-based Access Control (RBAC) and the notion of organizational positions, it seems easy to construct role hierarchies. This is...
