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 ...

In this paper, we revisit the security of several message authentication code (MAC) algorithms based on block ciphers, when instantiated with 64-bit block ciphers such as DES. We e...

We investigate some of the algebraic properties of the SAFER block cipher when the message space is considered as a Z-module. In particular we consider the invariant Z-submodules ...

In this paper we present the block cipher Rijndael, which is one of the fifteen candidate algorithms for the Advanced Encryption Standard (AES). We show that the cipher can be impl...

In this paper we define a notion of leak extraction from a block cipher. We demonstrate this new concept on an example of AES. A result is LEX: a simple AES-based stream cipher wh...
