I found the one-way functions rather interesting in the reading today. Also, the notion of one-way functions is interesting. It was a little difficult to understand the theory behind one-way functions and public key theory in general. I'm wondering if there will ever be a time that our "one-way" functions are no longer one way, either due to our computing power or mathematical skills.
It is interesting to recognize that one-way functions exist, where the original function is very accessible but the inverse is not. I wonder if there is an efficient one-way function out there; I know RSA is sometimes unfeasible to use because of time constraints. Perhaps there are more feasible public-key systems that are more commonly used.
