Our investigating challenge is to enable keyword queries on an encrypted cloud storage. We design a secure indexes schema based on the work of Eu-Jin Goh and Hore et al. Our implementation using a modified version of Bloom filter yields similar security level to Hore’s report, but provides flexible control over the performance-security tradeoff on every single query. Preliminary experiments are conducted to evaluate the efficiency and performance of the system against real-world large datasets.
