This book offers a mathematical foundation for modern cryptography. It is primarily intended
as an introduction for graduate students. Readers should have basic knowledge of …

A two-party key agreement problem with public discussion, known as the source model
problem, is considered. By relating key agreement to hypothesis testing, a new coding …

Hypergraphical sources are a natural class of sources for secret key generation, within
which different subsets of terminals sharing secrets are allowed to discuss publicly in order …

We propose a lattice-based scheme for secret key generation from Gaussian sources in the
presence of an eavesdropper, and show that it achieves the strong secret key capacity in the …

Secret key agreement (SKA) is an essential primitive in cryptography and information
security. In a multiterminal key agreement problem, there are a set of terminals each having …

We propose a lattice-based scheme for secret key generation from Gaussian sources in the
presence of an eavesdropper, and show that it achieves the strong secret key capacity in the …

We study a distributed sampling problem where a set of processors want to output
(approximately) independent and identically distributed samples from a given joint …

We consider the source model key agreement problem involving two legitimate parties and
an eavesdropper who observe n iid samples of X and Y and Z respectively. The best-known …

We study the change of multivariate mutual information among a set of random variables
when some common randomness is added to or removed from a subset of the random …

In this paper, we explore the connection between secret key agreement and secure
omniscience within the setting of the multiterminal source model with an eavesdropper …
