A measurement of the top quark pair production cross section in proton antiproton collisions at an interaction energy of {radical}(s)=1.96 TeV is presented. This analysis uses 405{+-}25 pb{sup -1} of data collected with the D0 detector at the Fermilab Tevatron Collider. Fully hadronic tt decays with final states of six or more jets are separated from the multijet background using secondary vertex tagging and a neural network. The tt cross section is measured as {sigma}{sub tt}=4.5{sub -1.9}{sup +2.0}(stat){sub -1.1}{sup +1.4}(syst){+-}0.3(lumi) pb for a top quark mass of m{sub t}=175 GeV/c{sup 2}.
