    Two Factor Access Control Using DNA Algorithm
    (2017-08-14T11:05:14Z) Keerthana, V; Konduru, Iswarya; Priyanka, G S
    In this paper, we introduce a new two-factor access control using DNA algorithm. Specifically, in our proposed two factor access control system, an attribute-based access control mechanism is implemented with the necessity of both a user secret key and a lightweight security device. As a user cannot access the system if they do not hold both, the mechanism can enhance the security of the system, especially in those scenarios where many users share the same computer for web-based services. In addition, attribute-based control in the system also enables the database to restrict the access to those users with the same set of attributes while preserving user privacy, i.e., the data base only knows that the user fulfills the required predicate, but has no idea on the exact identity of the user.
