Cloud computing and its applications have attracted great attention from both academia and industry in the past few years. Cloud computing offers powerful data storage and large-scale processing capabilities for users with the help from third-party centers. The benefits for users are obvious, such as efficient on-the-move data access and sharing can be enabled, the local expenditure cost on hardware and software can be saved, and the burden of complicated data storage management can be relieved. When user data are hosted on public cloud centers, the owner would lose the ability to physical access and control these data. Usually data users are not confident that cloud centers always provide secure and trusted services. Thus, cloud computing raises many security and privacy concerns to users in some fields including data confidentiality, integrity, security, availability, access control, and secure computing. To address these issues, some technologies and protocols have been proposed. This workshop aims to solicit the latest advances in securing cloud computing from both industry and academic researchers, and offers a platform to exchange their ideas and experiences.
