A Secure Shared Group Model of Cloud Storage

Cloud Computing has been envisioned as the next-wave system architectures of IT. Essentially, it can have ubiquitous access through variety of devices and applications provided by cloud service providers. In particular, cloud storage service brings benefits not only low cost and scalability, but also great appropriateness for group working, such as learning resource storage. However, the data security and privacy protection is still regarded as challenges. This paper aims the present problem, a secure shared group model of cloud storage is presented. With the using of crypto logical technology, the groups share their data security and efficiency. According to our security analysis and efficiency evaluation, the proposed model have lightweight overheads in terms of keys management as also security and confidentiality can be protected in cloud storage.
