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 …

The sponge duplex is a popular mode of operation for constructing authenticated encryption
schemes. In fact, one can assess the popularity of this mode from the fact that around $25 …

In this work, we evaluate the security of Merkle-Damgård (MD) hash functions and their
combiners (XOR and concatenation combiners) in quantum settings. Two main quantum …

Hash combiners are a practical way to make cryptographic hash functions more tolerant to
future attacks and compatible with existing infrastructure. A combiner combines two or more …

Over the past ten years, the statistical properties of random functions have been particularly
fruitful for generic attacks. Initially, these attacks targeted iterated hash constructions and …

We provide a survey about generic attacks on cryptographic hash constructions including
hash-based message authentication codes and hash combiners. We look into attacks …

The exclusive‐or (XOR) hash combiner is a classical hash function combiner, which is well
known as a good PRF and MAC combiner, and is used in practice in TLS versions 1.0 and …

Abstract At ASIACRYPT 2022, Benedikt, Fischlin, and Huppert proposed the quantum
herding attacks on iterative hash functions for the first time. Their attack needs exponential …

Encrypting too much data using the same key is a bad practice from a security perspective.
Hence, it is customary to perform re-keying after a given amount of data is transmitted. While …

目前, 在非平衡环境下的r-碰撞问题还没有得到有效的解决. 本文提出了一种新的高效算法来对r
个不同的非平衡函数寻找对应的r-碰撞. 新算法是将现有的r-碰撞算法, 并行碰撞搜索算法与非 …
