An Adaptive Two-Factor Authentication Scheme Based on the Usage of Schnorr Signcryption Algorithm

With the current continuous increase in usage of communication technologies and data transmission amount, available web services mobile applications are used to access complete several online activities such as education, e-commerce, financial transactions. The needs for a strong secure control authentication solution users’ resources crucial. Authentication can play major rule protection by implementing solution, which allows users prove their identities provide permission all legitimate only. This paper proposes two-factor scheme based on modified copy Schnorr Signcryption algorithm. proposed achieves target goal this paper, provides with an efficient that be implemented any second factor, no special requirement authenticate recourses permission. Moreover, Java-based application is developed order examine client/server architecture where it found successfully authorised reject unauthorised request adequate security level acceptable performance.
