|Abstract: ||Traditional password authentication has been used for many years, yet at the same time is
increasingly being attacked. Having realised the security breach and its potential damage to
existing online resources, most individuals have diverted their research interests to a more
secure authentication method.
Multifactor authentication requires the user to possess security devices that compute a
unique one time password, addressing “what the users’ possess” factor, as well as “what the
users’ know” factor in traditional password authentication.
Today’s most widely used implementations apply a time-synchronised approach to design
the computing algorithm. This involves tokens which read the time from an internal clock
when computing passwords. The password uniqueness is thus derived from the variable
Although much work has been done to date, further studies can be conducted using a nontime-
synchronised approach to ascertain whether such implementations can compute
passwords without the use of internal clock. Additional work can also be made on mobile
phone implementations with new algorithms that target improvements in user friendliness,
portability and ease of reach.
The purpose of this study is to derive a non-time-synchronised approach that can carry out
the same functionalities that of their counterparts. A prototype will be constructed to
demonstrate the proposed algorithm alongside further enhancements made to existing
implementations on mobile phones.|
