Practical implementations of secret-key generation are often based on sequential strategies,
which handle reliability and secrecy in two successive steps, called reconciliation and …

For a discrete or a continuous source model, we study the problem of secret-key generation
with one round of rate-limited public communication between two legitimate users. Although …

In the classical secret-key generation model, common randomness is generated by two
terminals based on the observation of correlated components of a common source, while …

This paper investigates the role of the eavesdropper's statistics in the implementation of a
practical secret-key generation system. We carefully conduct the information-theoretic …

In classical biometric authentication systems, the authenticity of each user is determined by
comparing two secret-keys which are generated based on the user's biometric enrollment …

Robust biometric authentication is studied from an information theoretic perspective.
Compound sources are used to account for uncertainty in the knowledge of the source …

Secure communication in a potentially hostile environment is becoming more and more
critical. The A rbitrarily V arying W iretap C hannel (AVWC) provides information-theoretical …

In the classical Secret-Key generation model, Common Randomness is generated by two
terminals based on the observation of correlated components of a common source, while …

In this work, secret-key generation based on a three-party compound source is studied
where the communication rate between legitimate users is limited. A robust secret-key …

I truly owe this thesis to my beloved family, who provided with its love and support for the last
26 years. My mom, Sandrine, who taught me her sense of esthetics and details, my dad …
