【 摘 要 】

Since the cloud storage technology has distribution, isolation and sharing characteristics, key management has become more and more difficulty. As a consequence, the research of key management technology has become a hot topic in recent years. In order to solve the untrustworthiness of cloud storage server provider, the complexity, security of key and some other issues under cloud storage environment, this paper proposed a (n+1,s+1) key management technology on the basis of Shamir (n,s) and then this technology was used in cloud storage system. The main idea of the technology is that the whole key spited into n+1 parts and distributed to the different cloud storage service providers and data owner to manage the sub-keys. Through the performance analysis, in this technology, the data owner is the core of the management process. The technology is more secure than the traditional technology and solves the untrustworthiness of cloud storage server provider based on the premise of reducing the burden of data owner.
