Webcryptography is based on the following empirically observed fact (here written as if it were carved in stone): Multiplying two integers is easy, but finding a nontrivial factor of an integer is hard. In other words, integer multiplication is in practice a “one-way function.” If a number is large, it’s essentially impossible to factor it. 11 WebJul 5, 2024 · Federal agency reveals the first group of winners from its six-year competition.
