METHOD AND APPARATUS FOR AUTHENTICATION

摘要

A method (500) of authentication using a near-field link comprises a first device (118) of a user generating (504) a random number, sending (504) the random number to a second device of the user over a near-field link; and sending (506) the random number to an authenticator device (104). At least one of the first device (118), the second device, or the user of the first (118) and second devices is authenticated (508, 510) upon the authenticator device (104) receiving the same random number from both the first (118) and second devices. Public safety radios (118) and other devices (116) may thereby be provided with a strong authentication method that does not require the user to input a password or other information to complete the authentication process.
