Abstract
Cloud computing is considered as the next step in the evolution of on-demand information technology which combines a set of existing and new techniques from research areas such as service-oriented architectures (SOA) and virtualization. With the rapid development of versatile cloud computing technology and services, it is routine for users to leverage cloud storage services to share data with others in a friend circle, e.g., Dropbox, Google Drive and AliCloud. He shared data in cloud servers, however, usually contains sers‘ sensitive information (e.g., personal profile, financial data, health records, etc.) and needs to be well protected. As the ownership of the data is separated from the administration of them, the cloud servers may migrate users‘ data to other cloud servers in outsourcing or share them in cloud searching. Therefore, it becomes a big challenge to protect the privacy of those shared data in cloud, especially in cross-cloud and big data environment. In order to meet this challenge, it is necessary to design a comprehensive solution to support user-defined authorization period and to provide fine-grained access control during this period. The shared data should be self destroyed after the user-defined expiration time. One of the methods to alleviate the problems is to store data as a common encrypted form. The disadvantage of encrypting data is that the user cannot share his/her encrypted data at a fine-grained level. When a data owner wants to share someone his/her information, the owner must know exactly the one he/she wants to share with.
