Webproposed [19,20]. For example, distinguishing attacks on HMAC/NMAC-MD5 and MD5-MAC were proposed in [20]. The inner near-collisions are used in the distinguisher which reveals more information than inner collisions. In the same work, they were able to recover partial subkey of the MD5-MAC as well. 1 by Zheng Yuan, Keting Jia, Wei Wang, and ...

Paper: Cryptanalysis on HMAC/NMAC-MD5 and MD5-MAC

WebThe ground-breaking results of Wang et al. have attracted a lot of attention to the collision resistance of hash functions. In their articles, Wang et al. give input differences, differential paths and the corresponding conditions that allow to find collisions with a high probability. However, Wang et al. do not explain how these paths were found.

WebOct 22, 2024 · The cryptanalysis of HMAC-MD5 is usually conducted together with NMAC (Nested MAC) since they are closely related. NMAC uses two independent keys K1 and K2 such that NMAC(K1, K2, M) = H(K1, H(K2, M), where K1 and K2 are used as secret initialization vectors (IVs) for hash function H(IV, M).
