Benefits of Coded Placement for Networks with Heterogeneous Cache Sizes
Abdelrahman M. Ibrahim, Ahmed A. Zewail, Aylin Yener
In this work, we study coded placement in caching systems where the users have unequal cache sizes and demonstrate its performance advantage. In particular, we propose a caching sc…
Coded Caching for Heterogeneous Systems: An Optimization Perspective
Abdelrahman M. Ibrahim, Ahmed A. Zewail, Aylin Yener
In cache-aided networks, the server populates the cache memories at the users during low-traffic periods, in order to reduce the delivery load during peak-traffic hours. In turn, t…
Device-to-Device Secure Coded Caching
Ahmed A. Zewail, Aylin Yener
This paper studies device to device (D2D) coded-caching with information theoretic security guarantees. A broadcast network consisting of a server, which has a library of files, an…
Universal Covertness for Discrete Memoryless Sources
Remi A. Chou, Matthieu R. Bloch, Aylin Yener
Consider a sequence of length emitted by a Discrete Memoryless Source (DMS) with unknown distribution . The objective is to construct a lossless source code that map…
Coded Caching in the Presence of a Wire and a Cache Tapping Adversary of Type II
Mohamed Nafea, Aylin Yener
This paper introduces the notion of cache-tapping into the information theoretic models of coded caching. The wiretap channel II in the presence of multiple receivers equipped with…
Learning an Adversary's Actions for Secret Communication
Mehrdad Tahmasbi, Matthieu R. Bloch, Aylin Yener
Secure communication over a wiretap channel is investigated, in which an active adversary modifies the state of the channel and the legitimate transmitter has the opportunity to se…
