An algorithm for MD5 single-block collision attack using high-performance computing cluster
hash functions MD5 computing cluster
2016/1/6
The parallel algorithm and its implementation for performing a single-block collision attack on
MD5 are described. The algorithm is implemented as MPI program based upon the source code of Dr Marc
S...
We present the hash function BLAKE2, an improved version of the SHA-3 finalist BLAKE optimized for speed in software. Target applications include cloud storage, intrusion detection, or version control...
Fast Collision Attack on MD5
Hash Function MD5 Differential Cryptanalysis Collision Attack Single-Block Collision
2013/4/18
We presented the first single block collision attack on MD5 with complexity of $2^{47}$ MD5 compressions and posted the challenge for another completely new one in 2010. Last year, Stevens presented a...
How To Find Weak Input Differences For MD5 Collision Attacks
MD5 Differential Collision Attack Divide-and-Conquer
2009/6/15
Since the first feasible collision differential was given for MD5 in 2004 by Wang et al, a lot
of work has been concentrated on how to improve it, but the researches on how to select weak input
diff...
Short Chosen-Prefix Collisions for MD5 and the Creation of a Rogue CA Certificate
MD5 collision attack certificate PlayStation 3
2009/6/12
We present a refined chosen-prefix collision construction for
MD5 that allowed creation of a rogue Certification Authority (CA) cer-
tificate, based on a collision with a regular end-user website ce...
1-MSB 输入差分可否成为MD5 算法最快碰撞攻击差分?
MD5 碰撞攻击 碰撞差分 差分路径
2009/6/9
迄今为止,已经发现MD5 算法的两个不同的3-bit 碰撞差分,其中一个由王小
云于2004 年发现并被最终改进至采用普通PC 机一分钟内可生成一对碰撞数据;另
一个由谢涛于2007 年发现,稍后被改进至半个小时之内即可产生一对碰撞数据。是
否存在更多的可行MD5 碰撞差分?是否存在更高效的MD5 碰撞搜索算法?
本文在抽象出MD5 算法可行碰撞差分路径性质的基础上,列出了所有构成可行

A New Collision Differential For MD5 With Its Full Differential Path
MD5 differential cryptanalysis collision attacks
2009/6/4
Since the first collision differential with its full differential path was presented for MD5 function
by Wang et al. in 2004, renewed interests on collision attacks for the MD family of hash function...
Preimage Attacks on 3-Pass HAVAL and Step-Reduced MD5
cryptanalysis hash function preimage attack
2009/6/4
This paper presents preimage attacks on the hash functions 3-pass HAVAL
and step-reduced MD5. Introduced in 1992 and 1991 respectively, these functions underwent
severe collision attacks, but no pre...
产生MD5碰撞的新的充分条件集
保密通信 MD5 碰撞攻击
2009/5/12
Wang Xiaoyun等(2005)给出了MD5能产生碰撞的一个充分条件集,并首次成功对MD5进行了碰撞攻击。Yuto Nakano等(2006)指出上述充分条件集中有16个条件是冗余的,并给出了其中14个条件冗余的原因。Liang Jie和Lai Xuejia(2005)指出Wang Xiaoyun等给出的充分条件集并非总能产生碰撞,并增加新的条件使之总能产生碰撞,同时提出了一个新的碰撞攻击算...
Joux and Wang’s multicollision attack has yielded collisions for several one-way hash algorithms. Of
these, MD5 is the most problematic due to its heavy deployment, but there exists a perception that...
Practical Attacks on Digital Signatures Using MD5 Message Digest
collision hash function MD5
2009/4/3
We use the knowledge of the single MD5 collision published by
Wang et al. [2] to show an example of a pair of binary self-extract packages
with equal MD5 checksums, whereas resulting extracted contr...
Wang et al [12] caused great excitement at CRYPTO2004
when they announced a collision for MD5 [11]. This paper is examines
the internal differences and conditions required for the attack to be succe...
Collisions for Hash Functions MD4, MD5, HAVAL-128 and RIPEMD
Hash Functions MD4 MD5 HAVAL-128 RIPEMD
2009/3/27
MD5 is the hash function designed by Ron Rivest [9] as a strengthened version of MD4 [8]. In 1993 Bert den Boer and Antoon Bosselaers [1] found pseudo-collision for MD5 which is made of the same messa...
In this paper, we present a fast attack algorithm to find two-block collision of hash function MD5. The algorithm is based on the two-block colli-sion differential path of MD5 that was presented by Wa...
In EUROCRYPT2005, a collision attack on MD5 was proposed by Wang et al. In this
attack, conditions which are sufficient to generate collisions (called “sufficient condition”) are introduced. This att...
