We present a generalized tweakable blockcipher HPH, which is constructed from a public random permutation PP and an almost-XOR-universal (AXU) hash function HH with a tweak and key schedule (t1,t2,K)∈...
Cogliati et al. introduced the tweakable Even-Mansour cipher constructed from a single permutation and an almost-XOR-universal (AXU) family of hash functions with tweak and key schedule. Most of previ...
The tweakable Even-Mansour construction generalizes the conventional Even-Mansour scheme through replacing round keys by strings derived from a master key and a tweak. Besides providing plenty of inhe...
We present XPX, a tweakable blockcipher based on a single permutation P. On input of a tweak (t11, t12, t21, t22) ∈ T and a message m, it outputs ciphertext c = P(m⊕∆1)⊕∆2, where ∆...
The iterated Even-Mansour construction defines a block cipher from a tuple of public $n$-bit permutations $(P_1,\ldots,P_r)$ by alternatively xoring some $n$-bit round key $k_i$, $i=0,\ldots,r$, and a...
