摘要Abstract: Abstract. As cloud computing becomes prevalent, more and more sensitive
data is being centralized into the cloud by users. To maintain the confidentiality
of sensitive user data against untrusted servers, the data should
be encrypted before they are uploaded. However, this raises a new challenge
for performing search over the encrypted data efficiently. Although
the existing searchable encryption schemes allow a user 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 new verifiable fuzzy keyword
search scheme based on the symbol-tree which not only supports
the fuzzy keyword search, but also enjoys the verifiability of the searching
result. Through rigorous security and efficiency analysis, we show that
our proposed scheme is secure under the proposed model, while correctly
and efficiently realizing the verifiable fuzzy keyword search. The extensive
experimental results demonstrate the efficiency of the proposed scheme.
