摘要：Currently, the Ministry of National Defense of Korea has established and is operating a DefenseIntegrated Data Center(DIDC) in order to provide a stable defense information service with low-cost andhigh efficiency. In fact, however, current version of DIDC is a physical aggregation of servers anddatabase systems operated widely in different places without core data center technologies such asintegrated security solutions or cloud computing technologies.In this paper, we propose a cloud computing based secure DIDC, called CS-DIDC, which is based oncloud computing, secret sharing, and erasure coding. Under CS-DIDC, individual user can protect his/herown sensitive data regardless of the data protection service provided by cloud service provider(CSP).
