Super-Strong RKA Secure MAC, PKE and SE from Tag-based Hash Proof System [PDF]

, 2016
$\mathcal{F}$-Related-Key Attacks (RKA) on cryptographic systems consider adversaries who can observe the outcome of a system under not only the original key, say $k$, but also related keys $f(k)$, with $f$ adaptively chosen from $\mathcal{F}$ by the ...
