Abstract
A secure onboard network communication method includes obtaining an initial value of a first freshness value (FV), obtaining a second value based on the initial value, and refreshing the initial value to the second value; sending a first message, where the first message includes the second value of the first FV; obtaining an initial value of a second FV, and when a first condition is met, refreshing the second FV to the second value, where the first condition includes a condition that the second value of the first FV is greater than or equal to a sum of the initial value of the second FV and a predetermined value.
Claims20
A secure onboard network communication method applied to a sending apparatus, wherein the secure onboard network communication method comprises:
- refreshing an initial value of a first freshness value (FV) to a second value, wherein the initial value is of a reset FV and is associated with a vehicle status parameter, wherein the vehicle status parameter comprises an accumulated driving mileage of a vehicle or an accumulated driving time of the vehicle, and wherein the second value is based on the initial value and is greater than the initial value;
- and
- sending a first message comprising the second value.
A secure onboard network communication method applied to a receiving apparatus, wherein the secure onboard network communication method comprises:
- receiving a first message comprising a second value of a first freshness value (FV);
- and
- refreshing an initial value of a second FV to the second value when a first condition is met,
- wherein the initial value is of a reset FV and is associated with a vehicle status parameter,
- wherein the vehicle status parameter comprises an accumulated driving mileage of a vehicle or an accumulated driving time of the vehicle, and
- wherein the first condition is that the second value is greater than or equal to a sum of the initial value and a predetermined value.
An onboard network sending apparatus, comprising:
- a memory configured to store instructions;
- and
- one or more processors coupled to the memory and configured to execute the instructions to cause the onboard network sending apparatus to:
- refresh an initial value of a first freshness value (FV) to a second value, wherein the initial value is of a reset FV and is associated with a vehicle status parameter, wherein the vehicle status parameter comprises an accumulated driving mileage of a vehicle or an accumulated driving time of the vehicle, and wherein the second value is based on the initial value and is greater than the initial value;
- and
- send a first message comprising the second value.
