Methods and user device and authenticator device for authentication of the user device
A method and a user device ( 110 ) for authentication of the user device ( 110 ) as well as a method and an authenticator device ( 120 ) for authentication of the user device ( 110 ) are disclosed. The user device ( 110 ) generates (A 030 ) a one-time password. The user device ( 110 ) sends (A 040 ), to an authenticator device ( 120 ), the one-time password as an acoustic signal, wherein the acoustic signal comprises a frequency within an ultrasound range or an infrasound range. The authenticator device ( 120 ) receives (A 050 ), from the user device ( 110 ), the one-time password. The authenticator device ( 120 ) validates (A 060 ) the one-time password.
1. A method, performed by a user device, for authentication of the user device, wherein the method comprises:
receiving a request for a one-time password, wherein the request was transmitted by an authenticator device, and wherein the request comprises location information indicating a location of the authenticator device and time information indicating the time at which the request was sent;
in response to the request, generating a one-time password based on the time information and the location information; and
sending to the authenticator device the one-time password as an acoustic signal, wherein the acoustic signal comprises a frequency within an ultrasound range or an infrasound range.
2. The method of claim 1 , wherein the method further comprises:
receiving, from the authenticator device, a response indicating success or failure of the authentication.
3. The method of claim 1 , wherein the method further comprises:
sending, to the authenticator device, authentication information, being independent of the one-time password.
4. A method, performed by an authenticator device, for authentication of a user device, wherein the method comprises:
determining that the user device is in the proximity of the authenticator device;
in response to determining that the user device is in the proximity of the authenticator device, transmitting to the user device a request for a one-time password, wherein the request for the one-time password comprises location information indicating a location of the authenticator device and time information indicating the time at which the request was sent;
receiving, from the user device, the requested one-time password as an acoustic signal, wherein the acoustic signal comprises a frequency within an ultrasound range or an infrasound range; and
validating the one-time password.
5. The method of claim 4 , wherein the validating of the one-time password is based on one or more authenticator parameters, wherein the one or more authenticator parameters comprises location of the authenticator device.
6. The method of claim 4 , wherein the validating of the one-time password is based on the request.
7. The method of claim 4 , wherein the method further comprises:
receiving, from the user device, authentication information, being independent of the one-time password.
8. The method of claim 4 , wherein determining that the user device is in the proximity of the authenticator device comprises receiving a signal transmitted by the user device; determining a received power of the received signal; and determining that the received power is above a threshold.
9. A user device configured for authentication of the user device, wherein the user device is configured for:
receiving a request for a one-time password, wherein the request was transmitted by an authenticator device, and wherein the request comprises location information indicating a location of the authenticator device and time information indicating the time at which the request was sent;
in response to the request, generating a one-time password based on the time information and the location information; and
sending to the authenticator device the one-time password as an acoustic signal, wherein the acoustic signal comprises a frequency within an ultrasound range or an infrasound range.
10. The user device of claim 9 , wherein the user device is configured for receiving, from the authenticator device, a response indicating success or failure of the authentication.
11. The user device of claim 9 , wherein the user device is configured for sending, to the authenticator device, authentication information, being independent of the one-time password.
12. An authenticator device configured for authentication of a user device, wherein the authenticator device is configured for:
determining that the user device is in the proximity of the authenticator device;
in response to determining that the user device is in the proximity of the authenticator device, transmitting to the user device a request for a one-time password, wherein the request for the one-time password comprises location information indicating a location of the authenticator device and time information indicating the time at which the request was sent;
receiving, from the user device, the requested on-time password as an acoustic signal, wherein the acoustic signal comprises a frequency within an ultrasound range or an infrasound range; and
validating the one-time password.
13. The authenticator device of claim 12 , wherein the authenticator device is configured for validating the one-time password based on one or more authenticator parameters, wherein the one or more authenticator parameters comprises the location information.
14. The authenticator device of claim 12 , wherein the request for the one-time password further comprises and identity of the authenticator device.
15. The authenticator device of claim 14 , wherein the authenticator device is configured for validating the one-time password based on the request.
16. The authenticator device of claim 12 , wherein the authenticator device is configured for receiving, from the user device, authentication information, being independent of the one-time password.
17. The authenticator device of claim 12 , wherein determining that the user device is in the proximity of the authenticator device comprises receiving a signal transmitted by the user device; determining a received power of the received signal; and determining that the received power is above a threshold.
18. A computer program product comprising a non-transitory computer readable medium storing a computer program comprising computer readable code units which when executed on a user device causes the user device to perform the steps of:
receiving a request for a one-time password, wherein the request was transmitted by an authenticator device, and wherein the request comprises location information indicating a location of the authenticator device and time information indicating the time at which the request was sent;
in response to the request, generating a one-time password based on the time information and the location information; and
sending to the authenticator device the one-time password as an acoustic signal, wherein the acoustic signal comprises a frequency within an ultrasound range or an infrasound range.
19. A computer program product comprising a non-transitory computer readable medium storing a computer program, comprising computer readable code units which when executed on an authenticator device causes the authenticator device to perform the steps of:
determining that the user device is in the proximity of the authenticator device;
in response to determining that the user device is in the proximity of the authenticator device, transmitting to the user device a request for a one-time password, wherein the request for the one-time password comprises location information indicating a location of the authenticator device and time information indicating the time at which the request was sent;
receiving, from the user device, the requested one-time password as an acoustic signal, wherein the acoustic signal comprises a frequency within an ultrasound range or an infrasound range; and
