Enhanced Certificate-Based Authentication for Distributed Environment

The unsecured open network is full of threats, viruses, and malicious Trojans. Digital certificates are one fundamental approach for providing safe and sound online security. In this paper, we propose a system that enables organizations to act as a CA and issue digital certificates to their clients. The client uses the certificates to access the services from the organization. The advantage of the proposed system is that it is more secure and faster than the other traditional systems. The various attacks relating to digital certificates were analyzed, and appropriate measures were suggested. These measures were considered in developing the proposed system. The paper also describes the procedure for generating, issuing, and revoking certificates and how it is implemented using Java platform.
