Abstract

Disclosed herein are a Bluetooth device and method for providing a service determined according to Bluetooth PIN. The Bluetooth device includes a storage unit, a reception unit, a control unit, a key generation unit and a transmission unit. The storage unit stores the types of services and security policies according to Bluetooth PIN. The reception unit receives a link key. The control unit searches for a Bluetooth PIN corresponding to the received link key. The key generation unit creates a security key in accordance with the search results and stored security policies. The transmission unit transmits data associated with a service using the created security key.

Claims

1. A Bluetooth device for providing a service determined according to a Bluetooth Personal Identification Number (PIN), comprising:

a storage unit configured to store types of services and security policies according to Bluetooth PIN;

a reception unit configured to receive a link key;

a control unit configured to search for a Bluetooth PIN corresponding to the received link key;

a key generation unit configured to create a security key in accordance with the search results and the stored security policies; and

a transmission unit configured to transmit data associated with a service using the created security key.

2. The Bluetooth device as set forth in claim 1, wherein the stored Bluetooth PINs are numbers that are previously set and stored manually or automatically.

3. The Bluetooth device as set forth in claim 1, wherein each of the security policies is information about the use of at least one of authentication, authorization, encryption and Secure Socket Layer (SSL).

4. The Bluetooth device as set forth in claim 3, wherein the security policy is information that applies at least one of a mandatory mode, an optional mode, a conditional mode and a determined-by-user mode to at least one of authentication, authorization, encryption and SSL.

5. The Bluetooth device as set forth in claim 1, wherein the security key comprises:

a link key created using the stored Bluetooth PINs; and

an encryption key created using the created link key.

6. The Bluetooth device as set forth in claim 1, wherein the transmission unit allows a Bluetooth link manager to provide the service according to the search results through authentication or encryption.

7. The Bluetooth device as set forth in claim 1, wherein the Bluetooth device is configured to serve a plurality of devices,

wherein each device of the plurality of devices contains a Bluetooth PIN,

wherein each device of the plurality of devices is served according a type of service and security policy according to its Bluetooth PIN, and

wherein the PIN of at least one device of the plurality of devices is identical to the PIN of another device of the plurality of devices.

8. A Bluetooth method of providing a service determined according to a Bluetooth pin, comprising:

storing types of services and security policies according to Bluetooth PIN;

receiving a link key;

searching for a Bluetooth PIN corresponding to the received link key;

creating a security key in accordance with the search results and the stored security policies; and

transmitting data associated with the service using the created security key.

9. The Bluetooth method as set forth in claim 8, wherein the stored Bluetooth PINs are numbers that are previously set and stored manually or automatically.

10. The Bluetooth method as set forth in claim 8, wherein each of the security policies is information about the use of at least one of authentication, authorization, encryption and Secure Socket Layer (SSL).

11. The Bluetooth method as set forth in claim 10, wherein the security policies is information that applies at least one of a mandatory mode, an optional mode, a conditional mode and a determined-by-user mode to at least one of the authentication, authorization, encryption and SSL.

12. The Bluetooth method as set forth in claim 8, wherein the operation of creating the security key comprises:

creating a link key using the stored Bluetooth PINs; and

creating an encryption using the created link key.

13. The Bluetooth method as set forth in claim 8, wherein the operation of providing the service is performed by allowing a Bluetooth link manager to provide the service according to the search results through authentication or encryption.

14. The Bluetooth method as set forth in claim 13, wherein the operation of providing the service comprises:

performing a link key exchange using the link key created according to the security policies;

creating the encryption key using a new link key created through the link key exchange; and

transmitting and receiving encrypted data using the encryption key.
