The Role of Feedback in Two-way Secure Communications
Xiang He, Aylin Yener
Most practical communication links are bi-directional. In these models, since the source node also receives signals, its encoder has the option of computing its output based on the…
Two-hop Secure Communication Using an Untrusted Relay
Xiang He, Aylin Yener
We consider a source-destination pair that can only communicate through an untrusted intermediate relay node. The intermediate node is willing to employ a designated relaying schem…
Interference Channels with Strong Secrecy
Xiang He, Aylin Yener
It is known that given the real sum of two independent uniformly distributed lattice points from the same nested lattice codebook, the eavesdropper can obtain at most 1 bit of info…
Cooperation with an Untrusted Relay: A Secrecy Perspective
Xiang He, Aylin Yener
We consider the communication scenario where a source-destination pair wishes to keep the information secret from a relay node despite wanting to enlist its help. For this scenario…
Providing Secrecy With Structured Codes: Tools and Applications to Two-User Gaussian Channels
Xiang He, Aylin Yener
Recent results have shown that structured codes can be used to construct good channel codes, source codes and physical layer network codes for Gaussian channels. For Gaussian chann…
Providing Secrecy with Lattice Codes
Xiang He, Aylin Yener
Recent results have shown that lattice codes can be used to construct good channel codes, source codes and physical layer network codes for Gaussian channels. On the other hand, fo…
