The noteworthy BABAR and Belle evidence for D{sup 0}-D{sup 0} mixing motivates us to study its impact on D{sup 0}{yields}K*{sup {+-}}K{sup {+-}} decays and their CP-conjugate processes. We show that both the D{sup 0}-D{sup 0} mixing parameters (x and y) and the strong phase difference between D{sup 0}{yields}K*{sup {+-}}K{sup {+-}} and D{sup 0}{yields}K*{sup {+-}}K{sup {+-}} transitions ({delta}) can be determined or constrained from the time-dependent measurements of these decay modes. On the {psi}(3770) and {psi}(4140) resonances at a {tau}-charm factory, it is even possible to determine or constrain x, y and {delta} from the time-independent measurements of coherent (D{sup 0}D{sup 0}){yields}(K*{sup {+-}}K{sup {+-}})(K*{sup {+-}}K{sup {+-}}) decays. If the CP-violating phase of D{sup 0}-D{sup 0} mixing is significant in a scenario beyond the standard model, it can also be extracted from the K*{sup {+-}}K{sup {+-}} events.
