Private Communication with Grand Juries

Mechanism Design with Private Communication

This paper relaxes an important assumption of the mechanism design literature: That communication between the principal and each of his agents is public. Doing so yields two important results. First, it simplifies significantly mechanisms and institutions and shows the major role played by sell-out contracts, nonlinear prices and all-pay auctions. Second, it restores continuity with respect to ...

Private Communication

The research work presented in this dissertation deals with the application of modulation and digital signal processing techniques in the field of optical communications. It focuses on the design of a 40Gb/s short-reach optical transmission system. For a given optical wavelength, capacity increase is generally achieved by pushing technological limits in order to augment the serial line rate of ...

Computationally Private Information Retrieval with Polylogarithmic Communication

We present a single-database computationally private information retrieval scheme with polylogarithmic communication complexity. Our construction is based on a new, but reasonable intractability assumption, which we call the Φ-Hiding Assumption (ΦHA): essentially the difficulty of deciding whether a small prime divides φ(m), where m is a composite integer of unknown factorization.

Location-Private Interstellar Communication

Mankind is actively trying to communicate with extraterrestrial life. However, historically the discovery of new civilizations has led to war, subjugation, and even elimination. With that in mind, we believe that for any attempted contact with extraterrestrials our location must not be revealed. Therefore, we focus on the problem of location-private interstellar communication. We approach this ...
