Cryptanalysis of ForkAES
Forkciphers are a new kind of primitive proposed recently by Andreeva et al. for efficient encryption and authentication of small messages. They fork the middle state of a cipher and encrypt it twice under two...

Gimli : A Cross-Platform Permutation
This paper presents Gimli, a 384-bit permutation designed to achieve high security with high performance across a broad range of platforms, including 64-bit Intel/AMD server CPUs, 64-bit and 32-bit ARM smartphone...

Cryptographic Attack Metrics
When evaluating systems containing cryptographic components, the question arises how to measure the security provided by the cryptography included in the system. In this chapter we highlight the difficulties i...

The Saturation Attack — A Bait for Twofish
This paper introduces the notion of a “saturation attack”. Consider a permutation p over w-bit words. If p is applied to all 2w disjoint words, the set of outputs is exactly the same as the set of inputs. A satur...

Bias in the LEVIATHAN Stream Cipher
We show two methods of distinguishing the LEVIATHAN stream cipher from a random stream using 236 bytes of output and proportional effort; both arise from compression within the cipher. The first models the cipher...

Faster Luby-Rackoff ciphers
This paper deals with a generalization of Luby's and Rackoff's results [9] on the construction of block ciphers and their consequences for block cipher implementations. Based on dedicated hash functions, block...
