WebJun 7, 2012 · The first cryptographic collision attack against the cryptographic hash function MD5 was invented by Xiaoyun Wang et al. in 2004 [3], which however did not pose a serious immediate threat due to technical limitations. Subsequently, we have devised a more flexible collision attack against MD5 in 2007, a so-called chosen-prefix collision attack [4]. Webcollision attack (plural collision attacks) (cryptography) An attack on a cryptographic hash function that is able to find a hash collision (a pair of different inputs that have the same hash) faster than by brute force. Coordinate terms . preimage attack, second preimage attack; Translations
