To do this, draw horizontal lines through the graph. If any horizontal line intersects the graph more than once, then the graph does not represent a one-to-one function.

WebOct 8, 2015 · Assume h(x) is not one-way. This means, there exists an algorithm A, which for uniformly chosen x calculates a preimage x0 to h(x) = y‖xn with non-negligible probability. Since f(x0) = y, the algorithm A also computes a preimage for f(x) with non-neglible probability. This contradicts the assumption that f is one-way.
