a dispatch from the crypto wars review of matt curtin Brute Force Cracking the data encryption standard 2005
Social Science Research Network, 2006Co-Authors: Michael A FroomkinAbstract:Matt Curtin's Brute Force is a primarily personal account of one early effort to harness the power of distributed computing. In 1997, Mr. Curtin and other members of the DESCHALL (DES Challenge) project built, distributed, and managed software that united thousands of computers, many of them ordinary personal computers, in the search for a single decryption key among 72 quadrillion possibilities. The DESCHALL project sought to demonstrate that DES, then the U.S. national standard encryption algorithm, was no longer as secure as advertised. While Brute Force also offers some background on encryption regulation, export control policy, and other aspect of the Crypto Wars, it succeeds best as an almost diaristic account of the technical and organizational challenges at the heart of one of the earliest large- scale widely dispersed volunteer computing projects. The DES Cracking project chronicled in Brute Force exemplifies the interplay between technology and politics. More importantly, Brute Force reminds us that although we survived one round of the Crypto Wars without actual controls on the use of cryptography, and indeed with some substantial relaxation of the export control regime that stood in the way of the routine adoption of strong crypto in many types of software, that result was not inevitable – and might again come under threat.

research and implementation of md5 Brute Force Cracking algorithm based on cuda
Communications Technology, 2013Co-Authors: Lan TiaAbstract:CUDA( Compute Unified Device Architecture) is a popular research and application field in parallel computing. And a major challenge is how to refractor parallel program and maximize the crack speed. With the single-machine single-card and single-machine multi-card experimental environment platform built up previously,a series of parallel crypto algorithm are designed. On the other hand,the existing researches and implementions are mostly based on the single-machine single-card or single- machine multi-card mode. This paper proposes a general platform of GPU cluster for Brute-Force Cracking,and on this platform a series of experiments are done,thus to evaluate the robustness and effectiveness in Brute-Force Cracking of MDS algorithm. In addition,the experiments on this general platform could provide certain foundation for future design of crypto-analysis algorithm and enhancement of algorithm performance.

A homogeneous parallel Brute Force Cracking algorithm on the GPU
ICTC 2011, 2011Co-Authors: Jea-il Han, Hong-an Nguyen, Young Man KimAbstract:From the early days of computing, passwords have been considered as the essential authentication method to protect accesses to computer systems and users. Due to their importance, sensitiveness and confidentiality, many cryptography mechanisms have been utilized to secure password storage. Among them, cryptography hash methods are the most popular solutions. A cryptography hash function converts plaintext passwords to unreadable message digests which frustrates attackers from exploiting system failures and stealing stored passwords. On the other hand, it is possible to get the plaintext passwords from digests. We examined Brute Force attack to get the original passwords from the hashed ones and studied some existing GPU-based Brute Force Cracking tools. These applications implement a hybrid algorithm that generates available passwords on CPU side and hashes them in parallel on GPU side. In this paper, we propose a new homogeneous parallel Brute Force Cracking algorithm that performs all the works on GPU side. In our experiments, we successfully cracked many kinds of passwords. For example, with 6-digit passwords, it took about 0.23 ms for initialization, 1.97 ms for combination generation, and 52.81 ms for Brute-Force. So we need less than 1 second to crack passwords of this kind.
