Two Improved Multiple‐Differential Collision Attacks [PDF]
Mathematical Problems in Engineering, 2014 In CHES 2008, Bogdanov proposed multiple‐differential collision attacks which could be applied to the power analysis attacks on practical cryptographic systems. However, due to the effect of countermeasures on FPGA, there are some difficulties during the collision detection, such as local high noise and the lack of sampling points.

A Meaningful MD5 Hash Collision Attack [PDF]
, 2006 It is now proved by Wang et al., that MD5 hash is no more secure, after they proposed an attack that would generate two different messages that gives the same MD5 sum. Many conditions need to be satisfied to attain this collision.
