摘要：With the rapid development of cloud computing, cloud storage has become a cost effective solution for many users with the demand of data storage. However there are two major concerns like whether it is secured to store private data in cloud and security issues in data sharing scheme, with other users. There are five techniques discussed here in this paper Encrypted data sharing Collaborative key management protocol in CP-ABE, Time Domain attribute based access protocol (TAAC), Revisited attribute based data sharing scheme, Broadcast group key management (BGKM) and its secure construction called ACV-BGKM etc. But some problems exist in these methods. So to overcome these problems that are given in analysis and discussion a new improved method is proposed.
