Communication-Constrained Secret Key Generation: Second-Order Bounds

We study communication-constrained secret key generation, where two legitimate parties would like to generate a secret key using communication subject to a rate constraint. The problem is studied in the finite-blocklength regime. In this regime, the use of ...

On Measuring Linkability of Multiple Protected Biometric Templates Using Maximal Leakage

Yanina Yurina Shkel, Hatef Otroshi Shahreza

With the rapid development of biometric recognition systems, users can be simultaneously enrolled in multiple biometric recognition systems, either with a single or multiple biometric characteristics (e.g., face, voice, etc.). With such a growth of biometr ...

Binary Maximal Leakage

Yanina Yurina Shkel

Given two random variables X and Y, the maximal leakage L(X → Y) from X to Y was recently proposed as an operational privacy measure. Maximal leakage quantifies the multiplicative increase of the probability of correctly guessing any randomized function of ...

Measuring Linkability of Protected Biometric Templates Using Maximal Leakage

Yanina Yurina Shkel, Hatef Otroshi Shahreza

As the applications of biometric recognition systems are increasing rapidly, there is a growing need to secure the sensitive data used within these systems. Considering privacy challenges in such systems, different biometric template protection (BTP) schem ...

Information Spectrum Converse for Minimum Entropy Couplings and Functional Representations

Yanina Yurina Shkel

Given two jointly distributed random variables (X,Y), a functional representation of X is a random variable Z independent of Y, and a deterministic function g(⋅,⋅) such that X=g(Y,Z). The problem of finding a minimum entropy functional representation is kn ...

Secrecy by Design With Applications to Privacy and Compression

Yanina Yurina Shkel

Secrecy by design is examined as an approach to information-theoretic secrecy. The main idea behind this approach is to design an information processing system from the ground up to be perfectly secure with respect to an explicit secrecy constraint. The pr ...

Secret Key Generation Over Wireless Channels Using Short Blocklength Multilevel Source Polar Coding

Yanina Yurina Shkel

This paper investigates the problem of secret key generation from correlated Gaussian random variables in the short block-length regime. Inspired by the state-of-the-art performance provided by polar codes in the short blocklength regime for channel coding ...
