This paper describes LOKI97, a new private key block cipher with 128-bit data and a 256-bit key schedule, which can be initialised by 128, 192, or 256-bit keys. The data computation uses 16 rounds of a balanced Feistel network with a complex function f which incorporates two S-P layers. The 256-bit key schedule uses 48 rounds of an unbalanced Feistel network using the same complex function f to generate the subkeys. The cipher specication is given, followed by some background and design considerations, and a preliminary analysis.read more

A High-Performance Flexible Architecture for Cryptography
TL;DR: This paper describes how various proposed AES algorithms could be implemented on PipeRench, a reconfigurable fabric that supports implementations which can yield better than custom-hardware performance and yet maintains all the flexibility of software based systems.
Statistical cryptanalysis of block ciphers
TL;DR: This thesis aims to add a (small) stone to the wall of provable security of block ciphers with the (theoretical and experimental) statistical analysis of the mechanisms behind Matsui's linear cryptanalysis as well as more abstract models of attacks.
