Abstract
Enterprise users access several applications and services routinely to carry out their work-related activities on a day-to-day basis. These applications and services could be hosted within an enterprise or on a third-party data center. The enterprise users login into the applications and services so as to gain access to the applications and services. In the case of single sign-on, it is expected that the users authenticate once to a specific application/service/system and obtain access to any other application/service/system. In such a scenario, it is important to ensure that during the course of this authenticated access grant, the right users are provided access to right information. This is achieved by a re-authentication system that demands minimum re-authentication effort from 'right' users and maximum re-authentication effort from 'non-right' users. A system and method of on the fly re-authentication involves a novel challenge-response mechanism.
