Cloud computing is a new computing style which provides IT infrastructure and software as dynamic, scalable, and pay-per-use services. One of its characteristics is that enterprise data are hosted by storage service providers in the cloud. Hence strong data security must be taken into account for planning migration of business applications into the cloud.In this paper we analyze privacy requirements for the cloudapplications and discuss data encryption approaches for securing ecommerce applications in the cloud. To provide quantitative estimation of performance penalties caused bydata encryption, we made a benchmark for an onlinemarketplace application as a case study. Lessons learned from the benchmark are also discussed in the paper to provide some recommendations for avoiding unnecessary encryption costs.
