Abstract
There is provided a method (100) of authenticating a first device (120) to a second device (110) based on a number of data elements and based on a predefined recombination function known by the first device and the second device. The method is executable by the first device and comprises receiving (101) an input signal by the first device from the second device, the input signal being indicative of selected ones of the data elements, generating (102), by the first device, an authentication signal by using the recombination function and based on the selected data elements as input elements, wherein the authentication signal represents a basis for the second device for authenticating the first device, and sending (103) the authentication signal to the second device.
Claims15
A method of authenticating a first device to a second device based on a number of stored data elements and based on a predefined recombination function known by the first device and the second device, the method being executable by the first device and comprising:
- receiving an input signal by the first device from the second device, the input signal being indicative of selected ones of the stored data elements;
- generating, by the first device, an authentication signal by using the predefined nonlinear recombination function and based on the selected ones of the stored data elements as input elements, wherein the authentication signal represents a basis for the second device for authenticating the first device;
- and
- sending the authentication signal to the second device.
A method of authenticating a first device to a second device based on a number of stored data elements and based on a predefined recombination function known by the first device and the second device, the method being executable by the second device and comprising:
- sending an input signal by the second device to the first device, the input signal being indicative for selected ones of the stored data elements;
- receiving an authentication signal by the second device from the first device, the authentication signal being generated by the first device based on the input signal;
- generating, by the second device, a comparison signal by using the predefined nonlinear recombination function and based on the selected ones of the stored data elements as input elements, wherein the comparison signal represents a basis for the second device for authenticating the first device;
- and
- comparing the comparison signal and the authentication signal for authenticating the first device.

- a receiving unit configured to receive an input signal from the second device, the input signal being indicative of selected ones of the stored data elements;
- a generating unit configured to generate an authentication signal by using the predefined recombination function and based on the selected ones of the stored data elements as input elements, wherein the authentication signal represents a basis for the second device for authenticating the first device;
- and
- a sending unit configured to send the authentication signal to the second device.
A second device for authenticating a first device to the second device based on a number of stored data elements and based on a predefined nonlinear recombination function known by the first device and the second device, the second device comprising:
- a sending unit configured to send the input signal to the first device, the input signal being indicative for selected ones of the stored data elements;
- a receiving unit configured to receive an authentication signal from the first device, the authentication signal being generated by the first device based on the input signal;
- a generating unit configured to generate a comparison signal by using the predefined recombination function and based on the selected ones of the stored data elements as input elements, wherein the comparison signal represents a basis for the second device for authenticating the first device;
- and
- a comparing unit configured to compare the comparison signal and the authentication signal for authenticating the first device.
