Security of Cyclic Double Block Length Hash Functions
Abstract. We provide the first proof of security for Abreast-DM, one of the oldest and most wellknown constructions for turning a block cipher with n-bit block length and 2n-bit k...

Equivalent Keys of HPC
This paper presents a weakness in the key schedule of the AES candidate HPC (Hasty Pudding Cipher). It is shown that for the HPC version with a 128-bit key, 1 in 256 keys is weak i...

Compression Functions Suitable for the Multi-Property-Preserving Transform
Since Bellare and Ristenpart showed a multi-property preserving domain extension transform, the problem of the construction for multi-property hash functions has been reduced to th...
