Abstract
Nowadays, authentication is essential to identify the legal users in a network communication. Usually, there are few wars to achieve authentication over a publicly accessible network system in order to protect certain private data from the unauthorized users, ranging from simple ID/Password to Biometrics System. One of the most active areas in OTP(One Time Password) research today aims at exploiting OTP to provide authentication in the finance and security industry. OTP is usually discarded once it has been used. this prevents huge loophole of traditional authentication system which employs the same ID and Password every time. However this OTP system also has its weaknesses in surviving some attacks. this paper proposes an advanced OTP protocol using PingPong-128 without loop hole of pre-existing OTP.
