security - Collision Rate With NTLMv2 Hashing Technique In Windows -
im doing research assignment @ uni investigating hash functions.
with sha1 , (from can understand) hash techniques there (incredibly rarely) hash collisions. see here
can anyove give me figure of how hashing collision occurs in ntlmv2 (used in windows 7)?
thanks
tom
ntlmv2 hmac-md5 implementation. should noted collisions not affect hmacs. in order attacker generate collision md5 has complexity of (2^24.1)/2=2^23.1, don't believe such attack can mounted against ntlmv2. ii believe answer (2^128)/2=2^127. number thinking of md5 ideal message digest function, , of course no such ideal function can exist.
division 2 done account birthday paradox.
