1. A method for secured communication between Bluetooth devices, the method comprising:
- generating and setting a first temporary Bluetooth Device Address (BD_ADDR), if a detection request for adjacent Bluetooth devices is requested from a user in a secured mode;
broadcasting an inquiry message including the first temporary BD_ADDR;
performing Bluetooth communication with a Bluetooth device selected by the user from among Bluetooth devices corresponding to a received inquiry response message using the first temporary BD_ADDR; and
releasing and eliminating the first temporary BD_ADDR and setting a default BD_ADDR, when the Bluetooth communication is terminated.

Abstract
Provided is a method and apparatus for secured communication between Bluetooth devices. A temporary Bluetooth Device Address (BD_ADDR) is generated and set if a Bluetooth communication request is generated in a secured mode and Bluetooth communication is performed using the temporary BD_ADDR; when the Bluetooth communication is terminated, the temporary BD_ADDR is released and eliminated and a default BD_ADDR is set. Thus, it is possible to prevent another Bluetooth device from performing the Bluetooth communication without a bonding process, thereby enabling secured communication.

6. An apparatus for secured communication between Bluetooth devices, the apparatus comprising:
-
a Bluetooth module for performing a Bluetooth communication using a set Bluetooth Device Address (BD_ADDR); and a controller for generating and setting a temporary BD_ADDR if a Bluetooth communication request is generated in a secured mode, and releasing and eliminating the temporary BD_ADDR and setting a default BD_ADDR when the Bluetooth communication is terminated, wherein the controller generates and sets a first temporary BD_ADDR, if a detection request for adjacent Bluetooth devices is requested from a user in the secured mode, and releases and eliminates the first temporary BD_ADDR and sets the default BD_ADDR, when the Bluetooth communication is terminated, and wherein the Bluetooth module broadcasts an inquiry message including the first temporary BD_ADDR and performs the Bluetooth communication with a Bluetooth device selected by the user from among Bluetooth devices corresponding to a received inquiry response message using the first temporary BD_ADDR. - View Dependent Claims (7, 8, 9, 10)
