$\hat{I}\pm$-leakage Interpretation of Rényi Capacity

Ni Ding, Farhad Farokhi, Tao Guo +2

For $\tilde{f}(t)=\exp (\frac{\hat{I}\pm -1}{\hat{I}}\pm t)$, this paper shows that the Sibson mutual information is an $\hat{I}\pm$-leakage averaged over the adversary's $\tilde{f}$-mean relative informatio…
