New Bounds in Secret-Key Agreement: The Gap between Formation and Secrecy Extraction
Perfectly secret message transmission can be realized with only partially secret and weakly correlated information shared by the parties as soon as this information allows for the ...

The Bare Bounded-Storage Model: The Tight Bound on the Storage Requirement for Key Agreement
Abstract--In the bounded-storage model (BSM) for information-theoretic secure encryption and key agreement, one makes use of a random string R whose length t is greater than the as...

Information-Theoretic Key Agreement: From Weak to Strong Secrecy for Free
One of the basic problems in cryptography is the generation of a common secret key between two parties, for instance in order to communicate privately. In this paper we consider in...

Secure Device Pairing Based on a Visual Channel: Design and Usability Study
— “Pairing” is the establishment of authenticated key agreement between two devices over a wireless channel. Such devices are ad hoc in nature as they lack any common preshar...

Non-malleable extractors and symmetric key cryptography from weak secrets
We study the question of basing symmetric key cryptography on weak secrets. In this setting, Alice and Bob share an n-bit secret W, which might not be uniformly random, but the ad...
