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). If we re-write the HMAC equation … WebIn this paper, we present the first full key-recovery attacks on NMAC and HMAC instantiated with a real-life hash function, namely MD4.
