Physical layer security (PHY-security) takes the advantages of channel randomness nature
of transmission media to achieve communication confidentiality and authentication. Wiretap …

Recently, there has been great interest in physical layer security techniques that exploit the
randomness of wireless channels for securely extracting cryptographic keys. Several …

Due to the broadcast nature of wireless channels, wireless communication is vulnerable to
eavesdrop**, message modification, and node impersonation. Securing the wireless …

We study the design of cryptographic primitives resilient to key-leakage attacks, where an
attacker can repeatedly and adaptively learn information about the secret key, subject only …

Fuzzy extractors (Dodis et al., in Advances in cryptology—EUROCRYPT 2014, Springer,
Berlin, 2014, pp 93–110) convert repeated noisy readings of a secret into the same …

A long line of work in the past two decades or so established close connections between
several different pseudorandom objects and applications, including seeded or seedless non …

In this work, we study position-based cryptography in the quantum setting. The aim is to use
the geographical position of a party as its only credential. On the negative side, we show that …

In this paper we give improved constructions of several central objects in the literature of
randomness extraction and tamper-resilient cryptography. Our main results are:(1) An …

Consider two parties holding correlated random variables W and W′, respectively, that are
within distance t of each other in some metric space. These parties wish to agree on a …

Fuzzy extractors derive strong keys from noisy sources. Their security is usually defined
information-theoretically, with gaps between known negative results, existential …
