Collision attack

In cryptography, a collision attack on a cryptographic hash tries to find two inputs producing the same hash value, i.e. a hash collision. This is in contrast to a preimage attack where a specific target hash value is specified. There are roughly two types of collision attacks: Classical collision attackFind two different messages m1 and m2 such that hash(m1) = hash(m2). More generally: Chosen-prefix collision attackGiven two different prefixes p1 and p2, find two appendages m1 and m2 such that hash(p1 ∥ m1) = hash(p2 ∥ m2), where ∥ denotes the concatenation operation. (Wikipedia).

Elastic and Inelastic Collisions

When you take a shot on a pool table or tackle someone in a football game, you're participating in a collision. But the two events we just mentioned are totally different kinds of collisions! But what are elastic collisions, and what are inelastic collisions? We have to learn the varieties
