Secure Capacity Region for Erasure Broadcast Channels with Feedback
László Czap, Vinod M. Prabhakaran, Suhas Diggavi +1
We formulate and study a cryptographic problem relevant to wireless: a sender, Alice, wants to transmit private messages to two receivers, Bob and Calvin, using unreliable wireless…
Subspace Properties of Network Coding and their Applications
Mahdi Jafari Siavoshani, Christina Fragouli, Suhas Diggavi
Systems that employ network coding for content distribution convey to the receivers linear combinations of the source packets. If we assume randomized network coding, during this p…
Exchanging Secrets without Using Cryptography
Iris Safaka, Mahdi J. Siavoshani, Uday Pulleti +4
We consider the problem where a group of n nodes, connected to the same broadcast channel (e.g., a wireless network), want to generate a common secret bitstream, in the presence of…
On the Sum-Capacity with Successive Decoding in Interference Channels
Yue Zhao, Chee Wei Tan, A. Salman Avestimehr +2
In this paper, we investigate the sum-capacity of the two-user Gaussian interference channel with Gaussian superposition coding and successive decoding. We first examine an approxi…
