  We investigate both theoretically and numerically the dynamics of
Out-of-Time-Ordered Correlators (OTOCs) in quantum resonance condition for a
kicked rotor model. We employ various operators to construct OTOCs in order to
thoroughly quantify their commutation relation at different time, therefore
unveiling the process of quantum scrambling. With the help of quantum resonance
condition, we have deduced the exact expressions of quantum states during both
forward evolution and time reversal, which enables us to establish the laws
governing OTOCs' time dependence. We find interestingly that the OTOCs of
different types increase in a quadratic function of time, breaking the freezing
of quantum scrambling induced by the dynamical localization under non-resonance
condition. The underlying mechanism is discovered and the possible applications
in quantum entanglement are discussed.
