Some of Ostrovsky's contributions to computer science include:

• 1990 Introduced (with R. Venkatesan and M. Yung) the notion ofhttps://services27.ieee.org/fellowsdirectory/home.html 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 [4]
• 1990 Introduced the first poly-logarithmic Oblivious RAM (ORAM) scheme.
• 1993 Proved (with A. Wigderson) equivalence ofone-way functions and zero-knowledge [5].
• 1996 Introduced (with R. Canetti, C. Dwork and M. Naor) the notion of deniable encryption [6].
• 1997 Introduced (with E. Kushilevitz) the first single server private information retrieval scheme [7] .
• 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.
