A theoretical model of c-axis transport properties in cuprates is proposed. Interplane and in-plane charge fluctuations make hopping between planes incoherent and diffusive (the in-plane momentum is not conserved after tunneling). The non-Drude optical conductivity σc(ω) and the power-law temperature dependence of the dc conductivity are generically explained by the strong fluctuations excited in the process of tunneling. Several microscopic models of the charge fluctuation spectrum are considered.
