Abstract
We investigate the problem of privately searching encrypted data that is structured in the form of knowledge. Our rationale in such an investigation lies on the potential emergence of knowledge-based search using natural language, which makes content searches more effective and is context-aware when compared with existing keyword searches. With knowledge-based search, indexes and databases will consist of data stored using knowledge representation techniques such as description logics and conceptual graphs. This leads naturally to the issue of how to privately search this data, especially when most existing searchable encryption schemes are keyword-based. We propose the first construction with CQA2-security for searching encrypted knowledge, where the knowledge is represented in a well-established formalism known as basic conceptual graphs. Our proposals are based on structured encryption schemes of Chase and Kamara [8].
