Zusammenfassung:A password-based authentication is still the most prevalent authentication method because of its convenience and easy implementations. Since a password is transmitted via network, it has an inherent vulnerability of password exposure to an attacker. A one-time password system reduces the risk of a security breach even when a password is exposed to an attacker, because the password is only meaningful at a given time. A grid data security system uses a technology, GridOne™, which allows the use of a one-time password without requiring preinstalled hardware or software infrastructures, and it provides strong security over conventional password-based authentication systems. We analyzed the weakness of the grid data security authentication system and provide a suggestion to compensate for its vulnerability.
