WebJun 4, 2015 · Before an actual cryptographic primitive is broken, it's extremely unlikely that there won't be warning signs, such as theoretical advances in a related topic, slight improvements in our understanding of the mathematical structure of the primitive that lead to small but still impractical reduction of computation requirements to break it, etc. WebOne-way permutations are an important cryptographic primitive, and it is not known if their existence is implied by the existence of one-way functions. A trapdoor one-way function or trapdoor permutation is a special kind of one-way function. Such a function is hard to invert unless some secret information, called the trapdoor, is known. population buffalo
