Differential Cryptanalysis Mod 232 with Applications to MD5


We introduce the idea of differential cryptanalysis mod 232 and apply it to the MD5 message digest algorithm. We derive a theory for differential cryptanalysis of the circular shift function. We demonstrate high-probability differentials which leave the message digest register unchanged for each of MD5's four rounds, and explain how more such differentials may be calculated.
