인터넷을 기반으로 하는 금융서비스를 제공함에 있어 보안성에 대한 필요성이 최근 들어 매우 중요시되어져가고 있으며, 이 분야에 대한 많은 연구가 진행되어 오고 있다. 국내 대부분의 은행 기관에서는 인터넷 뱅킹 서비스를 지원하고 있으나, 그 서비스 이용에 있어 윈도우 사용자에 국한되어 있는 실정이다. 본 논문에서는 리눅스 기반에서 보다 더 안전한 인터넷 뱅킹 서비스를 지원하기 위한 PKI 기반 기술을 제안한다.

One of very important features that are necessarily supported by clustered parallel computer systems is a single I/O system image in which users can access both the local and remote I/O resources transparently. In this paper, we propose an efficient disk sharing technique supporting a single disk I/O system image architecture. The design separates the I/O subsystem of a cluster into the file system and a set of virtual hard disk drivers. The virtual hard disk driver deals with a hard disk in the remote node as a local hard disk. All services provided by it are performed in the device driver level without any modification of file systems. Users can, therefore, access all the disks in the cluster regardless of their locations. Our virtual hard disk driver is implemented under the linux, and also tested in a linux cluster system. We find by experiments that it can successfully support a single disk I/O space, and at the same time it shows better performance than NFS. We are sure that this paper can be a guideline for single I/O space of other devices to be easily constructed.
