1 compute n as a product of two very large random prime numbers p and q although n is part of the public key, factors of n, p and q are kept secret. In computer science, a one-way function is a function that is easy to compute on every input. One-way functions are easy to compute but it is very difficult to compute the value of their inverse functions. Objectives present asymmetric-key cryptography distinguish between symmetric-key cryptography and asymmetric-key cryptography introduce trapdoor one-way functions.
