US 2011/0238995 A1 · METHODS FOR AUTHENTICATION USING NEAR-FIELD

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.

Dependent claims

A method of authentication using a near-field signal, the method comprising:

receiving, by a first device of a user having a first electronic serial number, a second electronic serial number from a second device of the user, wherein the second electronic serial number is received in a near-field signal;
deriving, by the first device, an authentication result as a function of at least one of the first or second electronic serial numbers;
and
sending the authentication result to an authenticator device to use in authenticating at least one of the first device, the second device, or the user of the first and second devices.

1 more element

A method of authentication using near-field, the method comprising:

a first device of a user having a first electronic serial number, performing:
receiving an authentication demand from an authenticator device;
receiving, from a second device of the user, a second electronic serial number that is communicated using near-field apparatus in the first and second devices;
deriving an authentication result as a function of at least one of the first or second electronic serial numbers;
sending the authentication result to the authenticator device, wherein the first and second electronic serial numbers are provisioned in the authenticator device to enable generation of an authentication response based on the authentication result;
and
receiving the authentication response from the authenticator device.
