Strong Converse for a Degraded Wiretap Channel via Active Hypothesis Testing
Masahito Hayashi, Himanshu Tyagi, Shun Watanabe
We establish an upper bound on the rate of codes for a wiretap channel with public feedback for a fixed probability of error and secrecy parameter. As a corollary, we obtain a stro…

Strong Converse and Second-Order Asymptotics of Channel Resolvability
Shun Watanabe, Masahito Hayashi
We study the problem of channel resolvability for fixed i.i.d. input distributions and discrete memoryless channels (DMCs), and derive the strong converse theorem for any DMCs that…

Converses for Secret Key Agreement and Secure Computing
Himanshu Tyagi, Shun Watanabe
We consider information theoretic secret key agreement and secure function computation by multiple parties observing correlated data, with access to an interactive public communica…
