Visualizing Secure Hash Algorithm (SHA-1) on the Web

2011
Cryptographic hash functions play an important role in modern cryptography. In this paper, we present web-based interactive visualization applets for teaching secure hash algorithm (SHA-1). The visualization applets lead to more efficient learning outcomes.

A New Strategy for Finding a Differential Path of SHA-1

2007
In this paper, we propose a new construction algorithm for finding differential paths of Round 1 of SHA-1 for use in the collision search attack. Generally, the differential path of Round 1 is very complex, and it takes much time to find one by hand. Therefore, we propose a new search algorithm that consists of three sub searches, naming the forward ...

Exploiting Coding Theory for Collision Attacks on SHA-1

2005
In this article we show that coding theory can be exploited efficiently for the cryptanalysis of hash functions. We will mainly focus on SHA-1. We present different linear codes that are used to find low-weight differences that lead to a collision. We extend existing approaches and include recent results in the cryptanalysis of hash functions. With our

Hardware Architecture and Cost Estimates for Breaking SHA-1

2005
The cryptanalysis of hash functions has advanced rapidly, and many hash functions have been broken one after another. The most popular hash function SHA-1 has not been broken yet, but the new collision search techniques proposed by Wang et al. reduced the computational complexity down to 269, which is only 1/2,000 of the 280 operations needed for a ...
