Abstract: A secured communication method for a V2X communication device is disclosed. The secured communication method for a V2X communication device comprises the steps of; receiving at least one message on the basis of V2X communication; extracting adaptive certificate pre-distribution (ACPD) target information when the at least one message includes the ACPD target information; pre-authenticating at least one short-term certificate acquired from the ACPD target information; collecting at least one pre-authenticated short-term certificate to be broadcasted at a specific predicted time at a specific predicted location; and broadcasting an ACPD group (ACPDG) message including the collected at least one pre-authenticated short-term certificate at the specific predicted location at the specific predicted time.

Abstract: Disclosed is a V2X communication method of a V2X communication device. The V2X communication method can comprise the steps of: detecting misbehavior of a V2X communication device; determining whether or not the V2X communication device is in a potential misbehavior detection state; if the V2X communication device is in a potential misbehavior detection state, determining a reaction mode of the V2X communication device; and performing a predetermined operation in accordance with the reaction mode. The reaction mode can comprise at least one of a first mode, for deactivating a V2X communication function of the V2X communication device, a second mode, for activating only a reception function of the V2X communication device, and a third mode for activating the reception function and a limited transmission function of the V2X communication device.
