Abstract: A method for encoding and decoding TPMS data using a random code according to the present invention comprises the steps of generating a first password code using an ID reader; storing the first password code in at least one sensor to sense a tire state of a vehicle and transmitting the first password code to an ECU of the vehicle; generating a second password code before the sensor transmits a message; generating a secret data frame by encoding a data frame including TPMS system transceiving data of the vehicle into a second password code; generating a third password code based on the first password code and the second password code; and transmitting the secret data frame and the third password code. According to the method of the present invention, since the secret data frame is generated by encoding the TPMS transceiving data using an 8-bit random code and an independent password cord input in a process step, the secret data frames of the same type are not generated for respective vehicles. Therefore, compared to the prior invention which can decode wireless data only using the form and pattern thereof, vehicle communications security is enhanced. Also, since vehicle position tracking is not easy through the TMPS transceiving data and the communications security is excellent, user privacy can be protected due to the difficulties in acquiring internal transmitting/receiving information of the vehicle and tracking user position. In addition, since only the process of encoding/decoding the TPMS transceiving data is added to an existing device without adding or changing components, user convenience and economic feasibility can be improved using the existing device.
