Design and Implementation of High-Speed Certification Path Discovery Server on Public Key Infrastructure

공개키 기반 구조에서의 고속 인증 경로 탐색 서버의 설계 및 구현

In the field of secure information systems including electronic commerces, public key infrastructure(PKI) is widely used for secure services. The more PKI domains are established, the more needs are required for cross-domain certifications. Furthermore, each country has many certificate authorities(CA) which require more complex cross certification: We may need a fast algorithm in order to find the possible certification paths. This will be more indispensible in the growing PKI systems. We designed and implemented the high-speed certification path discovery algorithm. Also, we investigated the feature of operation of the system.
