Ensuring Scalable, Secured, Maintenance and Access Control of College Data, Using Cloud Computing

Cloud computing has been envisioned as the next-generation architecture of IT Enterprise. Privacy security is a key issue of cloud storage. Encryption is a well-established technology for protecting sensitive data. This paper addresses how to ensuring scalable, secured, maintenance and access control of college data storage in Cloud Computing. The problem of simultaneously achieving fine-grainedness, scalability, and data confidentiality of access control still remains unresolved. To overcome this problem, the authors defining and enforcing policies based on data attributes and allowing data owner to delegate most of the computation tasks involved in fine-grained data access control to untrusted cloud servers without disclosing the underlying data contents. They achieve this goal by exploiting and uniquely combining techniques of Attribute-Based Encryption (ABE), proxy re-encryption and lazy re-encryption.
