Secret-key Agreement with Channel State Information at the Transmitter
Ashish Khisti, Suhas Diggavi, Gregory Wornell
We study the capacity of secret-key agreement over a wiretap channel with state parameters. The transmitter communicates to the legitimate receiver and the eavesdropper over a disc…
Diversity Embedded Streaming Erasure Codes (DE-SCo): Constructions and Optimality
Ahmed Badr, Ashish Khisti, Emin Martinian
Streaming erasure codes encode a source stream to guarantee that each source packet is recovered within a fixed delay at the receiver over a burst-erasure channel. This paper intro…
Diversity Embedded Streaming Erasure Codes (DE-SCo): Constructions and Optimality
Ahmed Badr, Ashish Khisti, Emin Martinian
Streaming erasure codes guarantee that each source packet is recovered within a fixed delay at the receiver over a burst-erasure channel. This paper introduces a new class of strea…
Secret key agreement on wiretap channels with transmitter side information
Ashish Khisti
Secret-key agreement protocols over wiretap channels controlled by a state parameter are studied. The entire state sequence is known (non-causally) to the sender but not to the rec…
Secure Transmission with Multiple Antennas II: The MIMOME Wiretap Channel
Ashish Khisti, Gregory Wornell
The capacity of the Gaussian wiretap channel model is analyzed when there are multiple antennas at the sender, intended receiver and eavesdropper. The associated channel matrices a…
Interference Alignment for the Multi-Antenna Compound Wiretap Channel
Ashish Khisti
We study a wiretap channel model where the sender has transmit antennas and there are two groups consisting of and receivers respectively. Each receiver has a singl…
