Two-factor authentication (2FA) schemes that rely on a combination ofknowledge factors (e.g., PIN) and device possession have gained popularity.Some of these schemes remain secure even against strong adversaries that (a)observe the traffic between a client and server, and (b) have physical accessto the client's device, or its PIN, or breach the server. However, thesesolutions have several shortcomings; namely, they (i) require a client toremember multiple secret values to prove its identity, (ii) involve severalmodular exponentiations, and (iii) are in the non-standard random oracle model.In this work, we present a 2FA protocol that resists such a strong adversarywhile addressing the above shortcomings. Our protocol requires a client toremember only a single secret value/PIN, does not involve any modularexponentiations, and is in a standard model. It is the first one that offersthese features without using trusted chipsets. This protocol also imposes up to40% lower communication overhead than the state-of-the-art solutions do.
