Feasibility for improving the efficiency of the tag identification phase in OSK (Ohkubo, Suzuki i Kinoshita) RFID protocol is analyzed in this paper. First, the basic identification technique is presented in general. Then, a procedure for speeding up the identification by employment of TMTO (Time Memory Trade Off) approach is explained. Balancing between memory and time requirements is achieved with the chaining technique and introduction of an off-line, preparatory phase. As an additional effort, a second TMTObased level is proposed. It relies on a special look-up table which consists of the equidistant states generated during preparatory phase. The complexity of the proposed technique is discussed along with some numerical evaluation results obtained through experiments.
