Query: About set-theoretic properties of one-way functions   We investigate the problem of cryptanalysis as a problem belonging to the
class NP. A class of problems UF is defined for which the time constructing any
feasible solution is polynomial. The properties of the problems of NP, which
may be one-way functions, are established.
