Photoproduction of $K^*$ vector mesons off nucleon is investigated within theRegge framework where the electromagnetic vertex of $\gamma K^*K^*$ fully takesinto account the magnetic dipole and electric quadrupole moments of spin-1$K^*$ vector meson. The $t$-channel $K^*(892)$, $K(494)$ and $\kappa(800)$meson exchanges are considered for the analysis of the production mechanism.The experimentally observed rapid decrease of the cross sections for the$\gamma p \to K^{*+} \Lambda$ reaction beyond the resonance region is wellreproduced by the dominance of the exchange of $K$-meson trajectory. The roleof the scalar $\kappa$-meson trajectory is found to be minor in both $\gamma p$and $\gamma n$ reactions. The cross sections for the $\gamma n \to K^{*0}\Lambda$ reaction are predicted to be about twice those of the $\gamma p \toK^{*+}\Lambda$ reaction. The role of the $K^*$ electromagnetic multipoles andthe proton anomalous magnetic moment is studied through the total anddifferential cross sections and spin/parity asymmetries. We suggest themeasurement of the photon polarization asymmetry as a tool for identifying therole of the magnetic dipole and electric quadrupole moments of the $K^*$ vectormeson.
