Title: “Searchable Symmetric Encryption”
Short abstract: “Searchable Symmetric Encryption (SSE) has received a lot of research attention recently. To date, SSE schemes seem to provide the best tradeoffs between efficiency and security among different encrypted search solutions (e.g. property-preserving encryption, fully-homomorphic encryption, ORAM, functional encryption). Informally, SSE schemes encrypt a search structure which is outsourced to an untrusted server (e.g. in the cloud) together with the corresponding encrypted data collection. SSE enables clients to privately query the search structure in order to retrieve matching documents from the data collection. SSE has been studied in different security models and tradeoffs between security, efficiency and query expressiveness have been explored.”
