There is a great adventure of watermarking usage in the context of conventional authentication since it does not require additional storage space for supplementary metadata. Howeve…
Secret Key Agreement Over Multipath Channels Exploiting a Variable-Directional Antenna
Valery Korzhik, Viktor Yakovlev, Guillermo Morales-Luna +1
We develop an approach of key distribution protocol (KDP) proposed recently by T. Aono et al. A more general mathematical model based on the use of Variable-Directional Antenna (VD…
Key Distribution Protocols Based on Extractors Under the Condition of Noisy Channels in the Presence of an Active Adversary
Viktor Yakovlev, Valery Korzhik, Guillermo Morales-Luna +1
We consider in this paper the information-theoretic secure key distribution problem over main and wire-tap noise channels with a public discussion in presence of an active adversar…
Wet Paper Coding for Watermarking of Binary Images
