The XOR of two independent permutations (XoP) is a well-known construction for achieving
security beyond the birthday bound when implementing a pseudorandom function using a …

In this paper, we study the problem of lower bounding any given cost function depending on
the false positive and false negative probabilities of adversaries against indistinguishability …

We consider constructions that combine outputs of a single permutation $\pi:\{0, 1\}^
n\rightarrow\{0, 1\}^ n $ using a public function. These are popular constructions for …

A cryptosystem that performs compression before encryption may leak information about the
plaintext from the ciphertext length, giving rise to a compression side channel. An attacker …
