A new One-time Password Method
Yun Huang, Zheng Huang, Haoran Zhao, Xuejia Lai · IERI Procedia · 2013
One-Time Passwords (OTP) can provide complete protection of the login-time authentication mechanism against replay attacks. In this paper, we propose TSOTP: a new effective simple OTP method that generates a unique passcode for each use. The calculation uses both time stamps and sequence numbers. A two-factor authentication prototype for mobile phones using this method has been developed and has been used in practice for a year.
