This paper presents several methods to construct trapdoor block ciphers. A trapdoor cipher contains some hidden structure; knowledge of this structure allows an attacker to obtain ...

Feistel ciphers are very common and very important in the design and analysis of blockciphers, especially due to four reasons: (1) Many (DES-like) ciphers are based on Feistel’s ...

Matsui's linear cryptanalysis for iterated block ciphers is generalized to an attack called. This attack exploits a weakness that can be described by an e ective partition-pa...

In this paper we present a new 128-bit block cipher called Square. The original design of Square concentrates on the resistance against di erential and linear cryptanalysis. Howeve...

We propose secret-key cryptosystems MISTY1 and MISTY2, which are block ciphers with a 128-bit key, a 64-bit block and a variable number of rounds. MISTY is a generic name for MISTY...
