摘要：“Cloud Computing” Cloud computing is a type of computing that relies on sharing computingresources rather than having local servers or personal devices to handle applications. In cloud computing, theword cloud (also phrased as "the cloud") is used as a metaphor for "the Internet," so the phrase “cloudcomputing” means "a type of Internet-based computing," where different services such as servers, storage andapplications are delivered to an organization's computers and devices through the Internet. Cloud is aimed at sharing ofdata through internet. Data security and policy are the critical issues for remote data storage. A security user enforceddata access control mechanism must be provided before cloud users have the liberty to outsource sensitive data to thecloud for storage. Which can be overcome by Key-Policy Attribute-Based Encryption (KP-ABE) is a promisingcryptographic primitive which enables fine-grained access control over sensitive data.
