Is there a way to prove/create (or are there known hash functions) 2two hash functions that never have the same collision? I mean, like provable in way that someone who took 1one cryptography class in university can prove.
For example, I want hash functions A$A$ and B$B$ such that if hash function A$A$ collides on X$X$ and Y$Y$, then B$B$ will not collide on Xthese $X$ and Y.$Y$:
$$A(X) = A(Y) \quad \Rightarrow \quad B(X) \neq B(Y) $$
