Rateless coding with partial state information at the decoder
The problem of coding for channels with time-varying state is studied. Two different models are considered: one in which the channel state cannot depend on the transmitted signal,...

On the Secrecy Capabilities of ITU Channels
— We consider the secrecy inherent in the reciprocal nature of multipath fading channels and present a technique to generate a shared perfectly secret key by two terminals observ...

Increased Resilience in Threshold Cryptography: Sharing a Secret with Devices That Cannot Store Shares
Threshold cryptography has been used to secure data and control access by sharing a private cryptographic key over different devices. This means that a minimum number of these dev...

Noisy Tags: A Pretty Good Key Exchange Protocol for RFID Tags
We propose a protocol that can be used between an RFID tag and a reader to exchange a secret without performing any expensive computation. Similarly to the famous blocker tag sugge...

A Practical Attack on the Fixed RC4 in the WEP Mode
In this paper we revisit a known but ignored weakness of the RC4 keystream generator, where secret state info leaks to the generated keystream, and show that this leakage, also kno...
