We present a new message authentication code. It is based on a two trail construction, which underlies the unkeyed hash function RIPEMD-160. It is in comparison with the MDx-MAC ba...

The encryption system E0, which is the encryption system used in the Bluetooth specification, is examined. In the current paper, a method of deriving the cipher key from a set of ...
—For cryptographic applications, normal bases have received considerable attention, especially for hardware implementation. In this article, we consider fast software algorithms ...
Serpent is a 32-round AES block cipher finalist. In this paper we present several attacks on reduced-round variants of Serpent that require less work than exhaustive search. We at...
We present a method for finding efficient instruction sequences for the Serpent S-boxes. Current implementations need many registers to store temporary variables, yet the common ...
