Abstract :This paper presents a multi-proxy insert ignore into journalissuearticles values(2 proxies); based encrypted keyword search scheme that enjoys the following properties: This scheme provides data confidentially that encrypted data does not leak any keywords and documents to the attackers insert ignore into journalissuearticles values(data server and a proxy);. Moreover, the proposed scheme provides trapdoor privacy. In other words, the attackers do not learn any information about searched keywords. Furthermore, even if a proxy is controlled by an attacker, the attacker does not learn any information about the queries insert ignore into journalissuearticles values(keywords that the user searches over the database); and database results. Different from other studies, this scheme provides lightweight user-side query and data processing. In other words, most of the job insert ignore into journalissuearticles values(query processing); is done by the proxies on behalf of the user. Finally, the proposed scheme relaxes the trust assumption that eliminates a single point of failure by introducing multi-proxy architecture.
Keywords : data privacy, multi proxies, keyword search
