Methods for authentication using near-field
First Claim
1. A method for authentication comprising:
- generating, at a first device of a user, a number;
sending, by the first device to each of a second device of the user and an authenticator device, the number;
receiving, by the second device from the first device, the number;
sending, by the second device to the authenticator device, the number;
in response to receiving the same number from both the first and second devices, authenticating, by the authenticator device, the first device, the second device, and the user.

Abstract
Authentication methods are used to authenticate, a device1 having an ESN1 (electronic serial number), a device2 having an ESN2, and/or a user of the devices. In one implementation, device1 receives the ESN2 in a near-field signal; derives an authentication result as a function of the ESN1 and ESN2; and sends the authentication result to an authenticator device to use in completing authentication. Authentication is confirmed when the device1 authentication result matches an authentication result independently generated by the authenticator device, which is provisioned with the ESN1 and ESN2. In a second implementation, device1 generates a RAND1 (random number) and sends the RAND1 to device2 over a near-filed link. An authenticator device confirms authentication upon receiving the same RAND1 from both device1 and device2.

9. A system for authentication comprising:
-
a first device of a user that is configured to generate a number and send the number to each of a second device of the user and an authenticator device; the second device, wherein the second device is configured to receive the number from the first device and send the number to the authenticator device; and the authenticator device, wherein the authenticator device is configured to, in response to receiving the same number from both the first and second devices, authenticate the first device, the second device, and the user. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
