Publications

Some of Ostrovsky's contributions to computer science include:

1990 Introduced (with R. Venkatesan and M. Yung) the notion of interactive hashing proved essential for constructing statistical zero-knowledge proofs for NP based on any one-way function (see NOVY and ECCC TR06-075).
1991 Introduced (with M. Yung) the notion of mobile adversary (later renamed proactive security) (see survey of Goldwasser or over 400 citations in Google Scholar)
1992 Proved the existence of asymptotically optimal software protection scheme (later renamed searching on encrypted data) assuming the existence of Tamper-resistant Microprocessor
1993 Proved (with A. Wigderson) equivalence of one-way functions and zero-knowledge .
1996 Introduced (with R. Canetti, C. Dwork and M. Naor) the notion of deniable encryption .
1997 Invented (with E. Kushilevitz) the first single server private information retrieval protocol (see over 400 citations in Google Scholar).
1997 Showed (with E. Kushilevitz and Y. Rabani) (1+ε) poly-time and poly-size approximate-nearest neighbor search for high-dimensional data for L1-norm and Euclidean space (see over 320 citations in Google Scholar).
