In the previous chapter, we discussed the idea behind a forward search attack on a public key cryptosystems. In certain applications, a forward search attack can be used against a hash function.

a. What is a forward search attack on public key encryption, and how is it prevented?

b. Describe one plausible use for a hash function where a forward search attack is feasible.

c. How can you prevent a forward search attack on a hash function?
