Dynamic authentication: Need than a choice

The increasing number of reported security vulnerabilities exploiting the weaknesses of static password based authentication methods, and the significant financial/brand loss caused to the enterprises due to those vulnerabilities are only highlighting the fact that the traditional static password based authentication solutions are no longer an adequate protection mechanism for serious enterprise applications. This necessitates enterprises to seriously explore and embrace more robust, secure, multi-factor, dynamic one-time password based authentication technologies into their IT infrastructure. In this work we discuss the various authentication schemes with their pros and cons and present an implemented two factor dynamic onetime password scheme using a mobile device.
