Problems solved by technology

[0008] In the past, in the communication between the vehicle and the vehicle portable device, since a special algorithm is used, even if a third party intercepts the communication content, it is difficult to analyze the signal and understand the content
However, when a malicious third party intercepts the content of the communication in general public wireless communication such as Bluetooth, there is a possibility of knowing the content
In particular, when highly confidential information such as the parking position is leaked to a malicious third party, there is a concern of causing vehicle theft, etc.
