Multi-user Conjunctive Keyword Search Scheme over Ciphertext
Wu Q · 2013
Searchable encryption becomes increasingly significant with the prevalence of data outsourcing in cloud computing.To overcome the flaw in Yang et al.'s scheme that users have to provide all keywords,an improved one was proposed in this paper.The correctness,security and performance of the proposed scheme were analyzed in detail.It shows that the new scheme maintains the security properties of Yang et al.'s scheme but allows users to provide part of keywords.The new scheme performs well in terms of computational complexity,and can be applied to cloud computing wherethin clientis demanded.At last,a simple implementation of the new scheme was given.
