Secrecy and Privacy in Multi-Access Combinatorial Topology
Mallikharjuna Chinnapadamala, B. Sundar Rajan
In this work, we consider the multi-access combinatorial topology with caches where each user accesses a unique set of caches. For this setup, we consider secrecy, where ea…
Placement Delivery Arrays for Coded Caching with Shared and Private Caches
K. K. Krishnan Namboodiri, Elizabath Peter, B. Sundar Rajan
We consider a coded caching network consisting of a server with a library of files connected to users, where each user is equipped with a dedicated cache of size unit…
Two-Dimensional Multi-Access Coded Caching with Multiple Transmit Antennas
K. K. Krishnan Namboodiri, Elizabath Peter, B. Sundar Rajan
This work introduces a multi-antenna coded caching problem in a two-dimensional multi-access network, where a server with transmit antennas and files communicates to $K_1K_…
Private Information Delivery with Coded Storage
Kanishak Vaidya, B Sundar Rajan
In private information delivery (PID) problem, there are messages stored across servers, each capable of storing messages and a user. Servers want to convey one of the…
