OTP Bidirectional Authentication Scheme Based on MAC Address

With the development of Internet technology, the traditional static password based authentication solutions are no longer an adequate protection scheme to various enterprise applications. In this article, the principle of dynamic password technology is described, and the pros and cons of implementing dynamic password technology by software and hardware are analyzed as well. In addition, a dynamic password mutual authentication protocol base on MAC/IMEI of client is designed. The system architecture, authentication processes and safety measures are described and its security is also analyzed, which proves the high security features and wide application of such system. The new OTP scheme can be conveniently used and implemented with significant cost efficiency. It is mutual authentication and resistant to phishing attacks.
