Abstract: A method by which a first user terminal transmits a signal in a wireless communication system is disclosed. The method can comprise: monitoring a message related to the mobility of one or more user terminals; transmitting, to a second user terminal selected from among the one or more user terminals, a message for requesting to join a cluster to which the first user terminal belongs; receiving, from the second user terminal, a message for acknowledging joining of the cluster; and transmitting a message related to the mobility of the cluster. In addition, the second user terminal can be selected on the basis of comparison between the mobility of the cluster and the mobility of the second user terminal.

Abstract: Disclosed herein is a method of transmitting a collective perception message (CPM) at a vehicle-to-everything (V2X) communication apparatus of a vehicle. A method of transmitting V2X message of a vehicle includes generating a collective perception (CP) message including information on a plurality of objects detected by the vehicle, determining whether to fragment the CP message depending on whether a size of the CP message is greater than a predefined size, fragmenting the CP message based on the plurality of detected objects, upon determining that the CP message is fragmented, and transmitting the fragmented CP messages. Each of the fragmented CP messages comprises at least one of header information, information on the vehicle or sensor information used to detect the plurality of objects, which is included in the CP message.

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 method for inspecting the forgery/falsification of a private key of a V2X communication device. A first PKM random number message including information on an encrypted random number may be received from an external V2X communication device; the encrypted random number may be decrypted using a private key of a V2X communication device; the decrypted random number may be re-encrypted using a public key of the external V2X communication device; a second PKM random number message including information on the re-encrypted random number may be transmitted to the external V2X communication device; and a PKM result message including information on the result of a forgery/falsification inspection of the private key of the V2X communication device may be received from the external V2X communication device.
