Abstract(in English) | We point out that there exists a counterexample for the generic method to construct zero-way fuctions shown by Niemi-Renvall in Asiacrypt'94. Based on the notion of zero-way function, we then define the class of functions called no-way functions in this paper. This is a provable-security version of zero-way function. Intuitively, a function f is a no-way function if, without a trapdoor, computing f is as hard as some problem, and computing f<-1> is as hard as some (possibly different) problem. We give an example of no-way function such that computing f and f<-1> is proven to be as hard as breaking the Diffie-Hellman key exchange scheme. |
