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...
Towards a Characterization of the Related-Key Attack Security of the Iterated Even-Mansour Cipher
Iterated Even-Mansour cipher related-key attack
2016/7/20
We prove the related-key security of the Iterated Even-Mansour cipher under broad classes of related key derivation (RKD) functions. Our result extends the classes of RKD functions considered by Farsh...

The r-round (iterated) Even-Mansour cipher (also known as key-alternating cipher)
defines a block cipher from r fixed public n-bit permutations P1, . . . , Pr as follows: given a sequence
of n-bit r...
On the Provable Security of the Iterated Even-Mansour Cipher against Related-Key and Chosen-Key Attacks
block cipher ideal cipher related-key attacks
2016/1/4
The iterated Even-Mansour cipher is a construction of a block cipher from r public permutations P1,…,Pr which abstracts in a generic way the structure of key-alternating ciphers. The indistinguishabil...
