  • cryptographic hash function w/ a 60 bit hash,
  • on average 20 bits of work to hash a short document

On average how many bits of work would it take to find two short documents with the same hash

  • one beginning with the word “banana”
  • the other beginning with the word “fish”

solution

since I didn’t do this last time

  • There are 2^60 possible hashes
  • Each hash takes 2^20 time to compute
  • Due to the birthday attack, on average you need to find sqrt(2^60)=2^30 hashes

2^30*2^20=2^50 (50 bits of work)
