Generalized Tweakable Even-Mansour Cipher with Strong Security Guarantee and Its Applications
Tweakable Even-Mansour almost-XOR-universal hash functions HPH
2017/2/20
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)∈...
On the Provable Security of the Tweakable Even-Mansour Cipher Against Multi-Key and Related-Key Attacks
Tweakable Even-Mansour almost-XOR-universal hash functions multi-key attack
2016/12/29
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...
Multi-key Analysis of Tweakable Even-Mansour with Applications to Minalpher and OPP
Collision-based Cryptanalysis Minalpher OPP
2016/12/7
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...
XPX: Generalized Tweakable Even-Mansour with Improved Security Guarantees
XPX XEX Even-Mansour
2015/12/30
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 ∆...
Beyond-Birthday-Bound Security for Tweakable Even-Mansour Ciphers with Linear Tweak and Key Mixing
tweakable block cipher iterated Even-Mansour cipher key-alternating cipher
2015/12/23
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...
