The security of iterated message authentication code (MAC) algorithms is considered, and in
particular, those constructed from unkeyed hash functions. A new MAC forgery attack …

We study the nonlinearity and the weight of the rotation-symmetric (RotS) functions defined
by Pieprzyk and Qu. We give exact results for the nonlinearity and weight of 2-degree RotS …

Recent years have witnessed an exceptional research interest in cryptographic hash
functions, especially after the popular attacks against MD5 and SHA-1 in 2005. In 2007, the …

This paper deals with the security of iterated hash functions against generic attacks, such as,
eg, Joux'multicollision attacks from Crypto 04. The core idea is to increase the size of the …

Highly nonlinear balanced Boolean functions both satisfying the propagation criterion and
having almost uniform correlation values with all linear functions are very important in the …

The first designs of cryptographic hash functions date back to the late 1970s; more
proposals emerged in the 1980s. During the 1990s, the number of hash function designs …

In this paper, we propose, implement, and analyze the structures of two keyed hash
functions using the Chaotic Neural Network (CNN). These structures are based on Sponge …

The chaotic maps posses high parameter sensitivity, random-like behavior and one-way
computations, which favor the construction of cryptographic hash functions. In this paper, we …

A bstract Recently, the construction of Narain CFT from a certain class of quantum error
correcting codes has been discovered. In particular, the spectral gap of Narain CFT …

Quantum hash function is an important area of interest in the field of quantum cryptography.
Quantum hash function based on controlled alternate quantum walk is a mainstream branch …
