An Efficient Protocol for the Cross Certification Path Validation

경로기반 상호인증을 위한 효율적 프로토콜

With the expansion of E-commerce, Public Key Infrastructure (PKI) solutions are requited to resolve Internet security problems. But the certification mechanism for each organization has been independently developed under its own circumstances, so the cooperation of heterogeneous certification mechanisms must be carefully taken into account. In this paper, we propose an efficient protocol for the cross certification based on the path validation. The proposed “cross certification gateway” provides flexibility and convenience with the initial establishment protocol for the cross certification among different certification domains.
