Method for adaptively adjusting security level of V2X communication message and apparatus therefor
First Claim
1. A method of processing a vehicle-to-everything (V2X) message in a V2X message transmitting entity, the method comprising:
- obtaining, at the V2X message transmitting entity, status information of a transmission target entity;
determining a type of a V2X message to be transmitted to the transmission target entity;
adaptively determining a security level for the V2X message based on the type of the V2X message and a number of V2X messages that can be processed by the transmission target entity in a predetermined time duration;
generating the V2X message by applying a scheme for at least one of encryption, authentication, digital signature, or freshness check, the scheme being determined according to the determined security level; and
transmitting the V2X message to the transmission target entity,wherein the type of the V2X message includes at least one of a vehicle-to-vehicle (V2V) warning propagation, a V2V platooning, a V2V beaconing, or a vehicle-to-infrastructure (V2I) warning.

Abstract
A method of processing a vehicle-to-everything (V2X) message in a V2X message transmitting entity may comprise obtaining, at the V2X message transmitting entity, status information of a transmission target entity; determining adaptively a security level for a V2X message to be transmitted to the transmission target entity based on the obtained status information; and generating the V2X message according to the determined security level, and transmitting the V2X message to the transmission target entity. Because security levels of V2X messages are adaptively determined, the V2X messages can be processed according to a processing capability of the transmission target entity and the type of the V2X message, thereby assuring the safety of the driver.

8. A method of processing a vehicle-to-everything (V2X) message in a V2X message receiving entity, the method comprising:
-
obtaining, at the V2X message receiving entity, status information of the V2X message receiving entity, determining a type of a V2X message to be transmitted to the V2X message receiving entity; adaptively determining a security level of the V2X message based on the type of the V2X message and a number of V2X messages that can be processed by the V2X message receiving entity in a predetermined time duration, the security level determining a scheme for at least one of encryption, authentication, digital signature, or freshness check, the scheme being applied to generation of the V2V message for at least one counterpart entity; and transmitting a signal indicating the determined security level to the at least one counterpart entity, wherein the type of the V2X message includes at least one of a vehicle-to-vehicle (V2V) warning propagation, a V2V platooning, a V2V beaconing, or a vehicle-to-infrastructure (V2I) warning. - View Dependent Claims (9, 10, 11, 12)

13. A vehicle-to-everything (V2X) message processing apparatus mounted on a V2X message transmitting entity, comprising:
-
a processor executing at least one instruction; and a memory storing the at least one instruction executed by the processor, wherein the at least one instruction causes the processor to; obtain status information of a transmission target entity, determine a type of a V2X message to be transmitted to the transmission target entity, adaptively determine a security level of the V2X message to be transmitted to the transmission target entity based on the type of the V2X message and a number of V2X messages that can be processed by the transmission target entity in a predetermined time duration, generate the V2X message by applying a scheme for at least one of encryption, authentication, digital signature, or freshness check, the scheme being determined according to the determined security level, and transmit the V2X message to the transmission target entity, wherein the type of the V2X message includes at least one of a vehicle-to-vehicle (V2V) warning propagation, a V2V platooning, a V2V beaconing, or a vehicle-to-infrastructure (V2I) warning. - View Dependent Claims (14, 15)
