This tutorial reviews fundamental contributions to information security. An integrative
viewpoint is taken that explains the security metrics, including secrecy, privacy, and others …

We address security and privacy problems for digital devices and biometrics from an
information-theoretic optimality perspective to conduct authentication, message …

Secret-key agreement using physical identifiers is a promising security protocol for the
authentication of users and devices with small chips, owing to its lightweight security. In the …

This thesis addresses security and privacy problems for digital devices and biometrics,
where a secret key is generated for authentication, identification, or secure computations. A …

We analyze the fundamental trade-off of secret key-based authentication systems in the
presence of an eavesdropper for correlated Gaussian sources. A complete characterization …

The problem of secret-key based authentication under privacy and storage constraints on
the source sequence is considered. The identifier measurement channels during …

A basic model for key agreement with a remote (or hidden) source is extended to a multi-
user model with joint secrecy and privacy constraints over all entities that do not trust each …

We consider a distributed function computation problem in which parties observing noisy
versions of a remote source facilitate the computation of a function of their observations at a …

Secret-key agreement based on biometric or physical identifiers is a promising security
protocol for authenticating users or devices with small chips and has been extensively …

The problem of secret-key-based authentication under privacy and storage constraints on
the source sequence is considered. Identifier measurement channels during authentication …
