Abstract
Disclosed is an authentication method and system for a device using a Bluetooth technology. A method for performing authentication by a first device, using Bluetooth low energy (LE), according to an embodiment of the present invention comprises: authenticating a user on the basis of ID information of the user; and authenticating a device by comparing information acquired from a user input with information acquired using an exchanged public key. The authentication scheme for a device is determined according to the input/output capability of the device.
Claims20
A method of performing authentication by a first device using Bluetooth low energy (LE), the method comprising:
- forming a Bluetooth LE connection with a second device;
- obtaining identification information for identifying a user;
- performing a user authentication procedure of authenticating the user based on the identification information;
- transmitting, to the second device, a first notification message comprising an identifier corresponding to the identification information;
- receiving, from the second device, a write request message comprising a first public key;
- obtaining a first value for authentication of the second device using a first algorithm having the first public key as an input value;
- transmitting, to the second device, a second notification message comprising a second public key;
- and
- performing a device authentication procedure for authenticating the second device using a specific authentication method, and
- wherein the specific authentication method is determined based on an input/output capability of the first device.
A method of performing authentication by a first device using Bluetooth low energy (LE), the method comprising:
- forming a Bluetooth LE connection with a second device;
- transmitting, to the second device, a write request message to request a start of an authentication procedure;
- receiving, from the second device, a notification message comprising an identifier corresponding to identification information of a user;
- transmitting, to the second device, a write request message comprising a first public key;
- receiving, from the second device, a notification message comprising a second public key;
- obtaining a first value for authentication of the second device using a first algorithm having the second public key as an input value;
- performing a device authentication procedure for authenticating the second device using a specific authentication method;
- and
- transmitting, to the second device, a write request message representing results of the device authentication procedure,
- wherein the specific authentication method is determined based on an input/output capability of the first device.
A first device for performing authentication using Bluetooth low energy (LE), the first device comprising:
- memory storing data;
- and
- a processor controlling the memory,
- wherein the first device is configured to:
- form a Bluetooth LE connection with a second device;
- obtain identification information for identifying a user;
- perform a user authentication procedure of authenticating the user based on the identification information;
- transmit, to the second device, a first notification message comprising an identifier corresponding to the identification information;
- receive, from the second device, a write request message comprising a first public key;
- obtain a first value for authentication of the second device using a first algorithm having the first public key as an input value;
- transmit, to the second device, a second notification message comprising a second public key;
- and
- perform a device authentication procedure for authenticating the second device using a specific authentication method, and
- wherein the specific authentication method is determined based on an input/output capability of the first device.
