In this dissertation, we addressed three problems of SSE. First, we gave an SSE scheme which supports the multi-reader setting. Second, we proposed a generic solution for multi-keyword ranked search over the encrypted cloud data. Lastly, we proposed two forward/backward secure dynamic SSE which support geometric range search. Moreover, we introduced a security notion called content privacy which captures the leakages that are critical in the context of geometric range search but not considered by forward/backward security.
