US 9,544,768 B2 · Method and apparatus for performing secure Bluetooth communication

Abstract

A method for performing secure Bluetooth communication between a vehicle terminal and a user terminal is provided. The method includes: transmitting a user terminal inverse certificate request message to an authority server; receiving a message from the authority server in response to the transmission of the user terminal inverse certificate request message; obtaining a user terminal inverse certificate from the message received from the authority server; receiving a vehicle terminal inverse certificate from the user terminal in exchange for the user terminal inverse certificate; validating the vehicle terminal inverse certificate; pairing with the user terminal when the vehicle terminal inverse certificate is validated; and performing Bluetooth communication with the paired user terminal.

Dependent claims

A vehicle terminal for performing secure Bluetooth communication, comprising:

a communication unit configured to communicate with an authority server;
a validation unit configured to transmit a user terminal inverse certificate request message to the authority server through the communication unit, obtain a user terminal inverse certificate from a message received from the authority server in response to the transmitted user terminal inverse certificate request message, and validate a vehicle terminal inverse certificate received from the user terminal in exchange for the user terminal inverse certificate;
and
a Bluetooth communication unit configured to pair with the user terminal when the vehicle terminal inverse certificate is validated, and perform Bluetooth communication with the paired user terminal.

obtaining, by the vehicle terminal, a user terminal inverse certificate from the message received from the authority server;
receiving, at the vehicle terminal, a vehicle terminal inverse certificate from the user terminal in exchange for the user terminal inverse certificate;
validating, by the vehicle terminal, the vehicle terminal inverse certificate;
pairing, by the vehicle terminal, with the user terminal when the vehicle terminal inverse certificate is validated;
and
performing, by the vehicle terminal, Bluetooth communication with the paired user terminal.
