I'm interested the amount of avalanche involved with hash
functions.
Let's start by defining a measure: 'Avalanche Depth' which is 1
when there is just enough avalanche to make the input/output
probability of a function 0.5. If there is enough avalanche for
this to happen twice over, then the Avalanche Depth is 2 etc. I
appreciate this is rather a crude and at times very uneven
quantity, but the idea is to get an appreciation of the
effectiveness of hash functions.
Back to the question, can anyone supply the Avalanche Depth of a
round of hash functions such as SHA, MD5, Haval, RipeMD, Tiger
etc?
TIA,
Keith Lockstone.
