Oblivious keyword search (OKS) is a secure two party protocol such that the server has ( Data={(x_i,m_i)} ), and the client receives ( Search(w)={m_i mid w=x_i} ) for a search word $w$, where $x_i$ is a keyword and $m_i$ is the associated payload (database record). In the previous protocols, only the privacy of each party is proved. In this paper, we show the first fully secure OKS protocol under the DDH assumption in the CRS model. Not only the privacy of each party is proved, but also it is proved that the client outputs $Search(w)$ correctly even if the server is malicious. |
