Abstract: A method for authenticating a user in a session initiated on a computing device is disclosed herein. In a specific embodiment, the method comprises identifying a selection of an authentication verifier (801, 1101, 1205, 1305, 1405, 1505) from a set of possible authentication verifiers for the session, the selected authentication verifier (801, 1101, 1205, 1305, 1405, 1505) being 10 communicated within the session to the session user; identifying an authentication device (17) associated with an identifier for the session; providing at least two of the set of possible authentication verifiers for selection at the authentication device (17) for the session, the at least two of the set of possible authentication verifiers including the selected authentication verifier (801, 1101, 15 1205, 1305, 1405, 1505); receiving an authentication device selection from the authentication device (17) by a user’s selection from the at least two of the set of possible authentication verifiers; and determining if the authentication device selection matches the selected authentication verifier (801, 1101, 1205, 1305, 1405, 1505) as communicated within the session. A system for authenticating 20 the user in the session is also disclosed.

Abstract: A method of establishing a direct wireless communication link between a first device and a second device (the first device being designated as a sender and the second device being designated as a receiver) comprises: a proximity authentication operation that comprises determining, based on signals received by the first and second devices over one or more RF channels from a plurality of wireless access points, that the first device is proximate the second device; following the proximity authentication operation, a key generation operation that comprises: generating a shared secret by performing randomness extraction on respective signals received at the first and second devices over a selected channel of the one or more RF channels; and establishing the direct wireless communication link using the shared secret.
