Problem

Hash Function Requirements For a hash function to produce a fingerprint of a message or a file, it should have the following properties: H can be applied to a block of any size. H produces a fixed length output. H(x) should be easy to compute in terms of software and hardware. The function needs to be one-way or irreversible. This means that, given the output, it should be impossible to retrieve the hash function input. It should be impossible to find any input that produces the same digest as the following formula tells: It is impossible to find y, which is not equal to x such that H(y) = H(x). This is called weak collision resistant. It is impossible to find a pair (x,y) such that H(y)=H(x). Get the instant assignment help. Which is known as strong collision resistant?
