Why aren't trapdoor functions known?
Functions related to the hardness of the discrete logarithm problem (either modulo a prime or in a group defined over an elliptic curve) are not known to be trapdoor functions, because there is no known "trapdoor" information about the group that enables the efficient computation of discrete logs.

Why do we use trap doors?
For a programmer, trap doors make sense. If the programmer needs to modify the program sometime in the future, he can use the trap door instead of having to go through all of the normal , customer-directed protocols just to make the change. Trap doors should be closed or eliminated in the final version of the program after all testing is complete, but, intentionally or unintentionally, some are left in place. Other trap doors may be introduced by error and only later discovered by crackers who are roaming around, looking for a way into system programs and files. Typical trap doors use such system features as debugging tools, program exits that transfer control to privileged areas of memory, undocumented application calls and parameters, and many others.
When did computer hackers break into the Internet?
