A series of operation processes of the key management are elaborated, including key distribution, key updating and key agreement, etc. Analysis shows that the scheme can solve the problem of large-scale key management and storage issues in cloud storage effectively. The scheme feathers high efficiency and good scalability. It is able to resist collusion attack and ensure safe and reliable service provided by the cloud storaee system展开更多

Based on the existing theories and approaches, this paper discusses the categories and analysis procedure of security requirements in information systems. And according to the basic steps of security requirements analysis, the security hazard analysis model and the security risk analysis model are presented here. At the end, the methods of security requirements specification and the corresponding improvements are also introduced.展开更多
