Cloud computing emerges as a new computing paradigm that aims to provide reliable, customized
and quality of service guaranteed computation environments for cloud users.
Applications and databases are moved to the large centralized data centers, called cloud.
Due to resource virtualization, global replication and migration, the physical absence of
data and machine in the cloud, the stored data in the cloud and the computation results
may not be well managed and fully trusted by the cloud users. Most of the previous work
on the cloud security focuses on the storage security rather than taking the computation
security into consideration together. In this paper, we propose a privacy cheating discouragement
and secure computation auditing protocol, or SecCloud, which is a first protocol
bridging secure storage and secure computation auditing in cloud and achieving privacy
cheating discouragement by designated verifier signature, batch verification and probabilistic
sampling techniques. The detailed analysis is given to obtain an optimal sampling size
to minimize the cost. Another major contribution of this paper is that we build a practical
secure-aware cloud computing experimental environment, or SecHDFS, as a test bed to
implement SecCloud. Further experimental results have demonstrated the effectiveness
and efficiency of the proposed SecCloud.
