Dedicated hash functions are cryptographically secure compression functions which are
designed specifically for hashing. They intend to form a practical alternative for hash …

The goal of this paper is to discuss techniques for the protection of the authenticity of
information. The theoretical background is sketched, but most attention is paid to overview …

Collision resistant hash functions are an important basic tool for cryptographic applications
such as digital signature schemes and integrity protection based on “fingerprinting”. This …

In what follows we present the basic features of a proposed block cipher that is fast to
implement in software. In consideration of the uncharacteristically large block size, it might …

Attacks on double block length hash functions using a block cipher are considered in this
paper. We present a general free-start attack, in which the attacker is free to choose the …
