However, the traditional structure of CA is either hierarchical or reticular, and none of them is suitable for security require-nients come from the new trend in enterprise cooperation, namely virtual enterprise (VE). In this paper a new idea - virtual certificate authority (VCA), is proposed, as well as its implemen-tation. The goal of VCA is to provide global certificate service over vital enterprise while keeping CA of each participant intact as much as possible. Unlike PEM, PGP, and BCA, by using secret sharing scheme, virtual CA avoids the need for TTP and supports virtual enterprise's feature of dynamical construction and destruction.展开更多

The United Nations Convention on the Law of the Sea (hereinafter the “Convention”) is a major achievement of the UNCLOS III and the Agreement Relating to the Implementation of Part XI of the United Nations Convention on the Law of the Sea of 10 December 1982 (hereinafter the “1994 Agreement”) is an achievement of the informal consultations. The Enterprise regime has been dramatically changed in many ways with the adoption of 1994 Agreement. Envisaged as an operational organ of the International Seabed Authority, the outlook of the Enterprise is still unknown. In this connection, this paper highlights a few questions which need to be answered urgently, and proposes the way forward for the operationalization of the Enterprise in terms of legal principles and institutional design.展开更多
