Hardness Hypotheses, Derandomization, and Circuit Complexity
We consider hypotheses about nondeterministic computation that have been studied in different contexts and shown to have interesting consequences: • The measure hypothesis: NP d...

Tracking Complex Objects Using Graphical Object Models
We present a probabilistic framework for component-based automatic detection and tracking of objects in video. We represent objects as spatio-temporal two-layer graphical models, w...

The Complexity of Adding Failsafe Fault-Tolerance
In this paper, we focus our attention on the problem of automating the addition of failsafe fault-tolerance where fault-tolerance is added to an existing (fault-intolerant) progra...

Improved Non-committing Encryption Schemes Based on a General Complexity Assumption
Abstract. Non-committing encryption enables the construction of multiparty computation protocols secure against an adaptive adversary in the computational setting where private cha...

Zero-knowledge from secure multiparty computation
A zero-knowledge proof allows a prover to convince a verifier of an assertion without revealing any further information beyond the fact that the assertion is true. Secure multipar...
