Beyond eCK: Perfect Forward Secrecy under Actor Compromise and Ephemeral-Key Reveal
We show that it is possible to achieve perfect forward secrecy in two-message key exchange (KE) protocols that satisfy even stronger security properties than provided by the extend...

Verification of Secret Key Generation from UWB Channel Observations
Theoretical models of ultrawideband (UWB) radio channels indicate that pairs of UWB radio transceivers measure their common radio channel with a high degree of agreement and third ...

High-Rate Uncorrelated Bit Extraction for Shared Secret Key Generation from Channel Measurements
—Secret keys can be generated and shared between two wireless nodes by measuring and encoding radio channel characteristics without ever revealing the secret key to an eavesdropp...

Generic Constructions of Parallel Key-Insulated Encryption
Exposure of a secret key is a significant threat in practice. As a notion of security against key exposure, Dodis et al. advocated key-insulated security, and proposed concrete k...

Secret Key Generation for a Pairwise Independent Network Model
Abstract— We investigate secret key generation for a “pairwise independent network” model in which every pair of terminals observes correlated sources which are independent o...
