The cross section of the process e{sup +}e{sup -}{yields}K{sup +}K{sup -} was measured in the energy range {radical}(s)=1.04-1.38 GeV in the SND experiment at the VEPP-2M e{sup +}e{sup -} collider. The measured cross section is described by the model of vector meson dominance with contributions from the light vector mesons {rho}, {omega}, {phi} and their lowest excitations. The mean statistical accuracy of the measurement is 4.4%, and the systematic uncertainty is 5.2%.
