2009 International Conference on Networks Security, Wireless Communications and Trusted Computing, 2009
In 2005, collision resistance of several hash functions was broken by Wang et al. The strategy of determining message differential is the most important part of collision attacks against hash functions. So far, there are only three other message differentials attack published, one of which is 6 bits difference and two are 1 bit difference.

Enhancing MD5 Collision Susceptibility
Proceedings of the 4th International Conference on Industrial and Business Engineering, 2018Collision vulnerability of MD5 cryptographic hash function greatly affects the data integrity and authenticity of the hash value. In this study, the researchers introduced a new method for the padding process of the original message and implemented additional operations in the cryptographic hash function of MD5.

Design and Implementation of OTP Base on MD5
Applied Mechanics and Materials, 2014Encryption of information is getting increasingly large attention, due to the popularity of internet and the advance of technology. One of the encryption algorithms, MD5, is commonly used in data encryption nowadays. In this paper, MD5 algorithm was briefly described and used to construct a dynamic password encryption technique with time parameters ...

Improved Collision Attacks on MD4 and MD5
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2007At Eurocrypt'05, Wang et al. presented efficient collision attacks on MD5 and MD4 hash functions. They found a collision of MD5 with a complexity of less than 237 MD5 hash operations, and a collision of MD4 with complexity less than 28 MD4 hash operations. In their attack, the procedure to generate a collision is divided into 4 steps.

2008 International Conference on Advanced Computer Theory and Engineering, 2008
A new image retrieval method was introduced based on the combination of CBIR (content-based image retrieval) and MD5, after a brief introduction to current status of image retrieval technology. Kernel thought was that MD5 value was extracted from an image file and then indexed. These indexed MD5 values were used for image retrieval.

Collisions of MMO-MD5 and Their Impact on Original MD5
2011In this paper, we find collisions of MD5 in the Matyas-Meyer-Oseas mode and Miyaguchi-Preneel mode with a complexity of 239 operations, which runs contrary to the cryptographer's belief that these modes are stronger against collision attacks than the Davies-Meyer mode due to the impossibility of the message modification.

MD5 collisions and the impact on computer forensics
Digital Investigation, 2005In August 2004 at the annual cryptography conference in Santa Barbara, California a group of cryptographers, Xianyan Wang, Dengguo Feng, Xuejia Lai, Hongbo Yu, made the announcement that they had successfully generated two files with different contents that had the same MD5 hash.

An Improved Collision Attack on MD5 Algorithm
2008The research on the attack algorithm for a MD5 collision is one of the focuses in cryptology nowadays. In this paper, by analyzing the properties of the nonlinear Boolean functions used in MD5 and the differences in term of XOR and subtraction modulo 232, we prove that some sufficient conditions presented by Jie Liang and Xuejia Lai are also necessary ...

Debugging using MD5 process firewall
2014 International Conference on Contemporary Computing and Informatics (IC3I), 2014An Operating system (OS) is software that manages computer hardware and software resources by providing services to computer programs. One of the important user expectations of the operating system is to provide the practice of defending information from unauthorized access, disclosure, modification, inspection, recording or destruction.

Preimage Attacks on Step-Reduced MD5
2008In this paper, we propose preimage attacks on step-reduced MD5. We show that a preimage of a 44-step MD5 can be computed to a complexity of 296. We also consider a preimage attack against variants of MD5 where the round order is modified from the real MD5.
