With recent significant development in the portable device market, cloud computing is getting more and more utilized. Many sensitive data are stored in cloud central servers. To ensure privacy, these data are usually encrypted before being uploaded - making file searching complicated. Although previous cloud computing searchable encryption schemes al-low users to search encrypted data by keywords securely, these techniques only support exact keyword search and will fail if there are some spelling errors or if some morphological variants of words are used. In this paper, the authors provide the solution for fuzzy keyword search over encrypted cloud data.
