Among the studies of the properties of Standard Model particles, single-top production attracts particular attention due to its direct connection with the third row of the CKM matrix and its sensitivity to anomalous couplings of the top quark. A new analysis strategy has been developed to measure the t-channel single top quark cross section with the CMS detector, aiming at the confirmation of the recent observation of single-top quark production by the Tevatron experiments. This strategy has been designed in a scenario of 200 pb^-1 of data collected at a centre-of-mass energy of 10 TeV (as expected for the first long run of the Large Hadron Collider), with emphasis on the robustness against the systematics of a yet imperfectly calibrated detector and yet unknown amounts of background contamination.
