On Converse Results for Secure Index Coding
Yucheng Liu, Lawrence Ong, Parastoo Sadeghi +2
In this work, we study the secure index coding problem where there are security constraints on both legitimate receivers and eavesdroppers. We develop two performance bounds (i.e.,…

Independent User Partition Multicast Scheme for the Groupcast Index Coding Problem
Arman Sharififar, Neda Aboutorab, Yucheng Liu +1
The groupcast index coding (GIC) problem is a generalization of the index coding problem, where one packet can be demanded by multiple users. In this paper, we propose a new coding…

Secure Index Coding with Security Constraints on Receivers
Yucheng Liu, Parastoo Sadeghi, Neda Aboutorab +1
Index coding is concerned with efficient broadcast of a set of messages to receivers in the presence of receiver side information. In this paper, we study the secure index coding p…
