Abstract : Validation using partial passwords is a mode of authentication which is used in financial sector. This mode of authentication enhances security against attckers attemting to retrieve password by not allowing to realize the full password in a single attempt. Since the studies regarding partial password authentication are available comparatively less in the academic literature, many queries regarding it remain unanswered. In this paper, we propose a scheme for partial password authentication based on vector decomposition problem. The proposed scheme is based on a two-party protocol to securely evaluate 2DNF formula in higher dimensional vector spaces, using vector decomposition problem. The proposed scheme permits the user to select the arbitrary characters of the actual password to be entered, in random order.
