Secret Key Generation from Sparse Wireless Channels: Ergodic Capacity and Secrecy Outage
Tzu-Han Chou, Stark C. Draper, Akbar M. Sayeed
This paper investigates generation of a secret key from a reciprocal wireless channel. In particular we consider wireless channels that exhibit sparse structure in the wideband reg…
Key Generation Using External Source Excitation: Capacity, Reliability, and Secrecy Exponent
Tzu-Han Chou, Stark C. Draper, Akbar M. Sayeed
We study the fundamental limits to secret key generation from an excited distributed source (EDS). In an EDS a pair of terminals observe dependent sources of randomness excited by…
The Sender-Excited Secret Key Agreement Model: Capacity, Reliability and Secrecy Exponents
Tzu-Han Chou, Vincent Y. F. Tan, Stark C. Draper
We consider the secret key generation problem when sources are randomly excited by the sender and there is a noiseless public discussion channel. Our setting is thus similar to rec…
