摘要：Data outsourcing has attracted considerable attentions recently. It can not only bring high quality data service to users, it also reduces their burden of data storage and maintenance. As the confidentiality of sensitive data, it should be encrypted before outsourcing. To achieve search over the encrypted data becomes a challenging problem. Although the existing searchable encryption schemes allow users to search the encrypted data with confidentiality, these solutions cannot support the verifiability of searching result. We argue that a cloud server may be selfish in order to save its computation ability or bandwidth. For example, it may execute only a fraction of the search and returns part of the searching result. In this paper, we propose a novel verifiable fuzzy keyword search scheme based on the bloom filter which can support the fuzzy keyword search, while enjoying the verifiability of the searching result. Through rigorous security analysis, we show that our proposed scheme is se- cure under the proposed model, while correctly and efficiently realizing the verifiable fuzzy keyword search
