Abstract—User authentication is one of the fundamental
procedures to ensure secure communications and share system
resources over an insecure public network channel. Especially,
the purpose of the one-time password is to make it more
difficult to gain unauthorized access to restricted resources.
Instead of using the password file as conventional
authentication systems, many researchers have devoted to
implement various one-time password schemes using smart
cards, time-synchronized token or short message service in
order to reduce the risk of tampering and maintenance cost.
However, these schemes are impractical because of the far
from ubiquitous hardware devices or the infrastructure
requirements. To remedy these weaknesses, the attraction of
the QR code technique can be introduced into our one-time
password authentication protocol. Not the same as before, the
proposed scheme based on QR code not only eliminates the
usage of the password verification table, but also is a cost
effective solution since most internet users already have mobile
phones.
