Apparatus and method for preventing leakage of vehicle information

摘要

An apparatus and method for preventing the leakage of vehicle information in a normal communication environment by inserting fake communication data into vehicle communication traffic on a vehicle network. In the method for preventing leakage of vehicle information, a vehicle information leakage prevention apparatus connected to an in-vehicle module analyzes a vehicle communication protocol between the module and another module. It is determined whether encryption has been applied to the vehicle communication protocol, based on results of analysis of the vehicle communication protocol. A method of generating fake communication data is selected depending on whether encryption has been applied to the vehicle communication protocol. A fake communication data is generated depending on the selected method, and the generated fake communication data is transferred to a vehicle information leakage prevention apparatus connected to the other module.

1. A method for preventing leakage of vehicle information, comprising:
analyzing, by a vehicle information leakage prevention apparatus connected to an in-vehicle module, a vehicle communication protocol between the module and another module; determining whether encryption has been applied to the vehicle communication protocol, based on results of analysis of the vehicle communication protocol; selecting a method of generating fake communication data depending on whether encryption has been applied to the vehicle communication protocol; and generating fake communication data depending on the selected method, and transferring the generated fake communication data to a vehicle information leakage prevention apparatus connected to the other module, wherein transferring the generated fake communication data comprises, if it is determined that encryption has not been applied to the vehicle communication protocol, inserting a normal OTP into communication data when status of communication between the modules is normal, and inserting a random OTP into the communication data when the status of communication is fake, thus generating the fake communication data.
