Searchable Keyword-Based Encryption
To solve the problem of searching on encrypted data, many keyword search schemes have been proposed in recent years. The goal of such schemes is to enable a user to give an untrusted storage server the ability only to test whether an encrypted document contains a few keywords without learning anything else about the document. In this paper, we are concerned with decrypting the searched results ...
متن کاملSearchable Encryption with Keyword-Recoverability
Searchable encryption has many applications including email systems and storage systems. The usefulness of searchable encryption derives from its support of keyword-testability. Keyword-testability means that a receiver of a ciphertext can test whether the ciphertext contains a specific keyword. Recently, Bellare et al. suggested an efficientlysearchable encryption scheme with keyword-recoverab...
متن کاملA Study of Conjunctive Keyword Searchable Schemes
We study the development of conjunctive keyword searchable scheme which enables one to search encrypted documents by using more than one keyword. The notion of conjunctive keyword searching was presented by Golle et al. in 2004. However, their security model was constructed in a symmetric-key setting which is not applicable for the overall applications in the reality. So Park et al. extended Go...
متن کاملFFSSE: Flexible Forward Secure Searchable Encryption with Efficient Performance
Searchable Symmetric Encryption (SSE) has been widely applied in the design of encrypted database for exact queries or even range queries in practice. In spite of its efficiency and functionalities, it always suffers from information leakages. Some recent attacks point out that forward privacy is the desirable security goal. However, there are only a very small number of schemes achieving this ...
متن کاملForward-Secure Searchable Encryption on Labeled Bipartite Graphs
Forward privacy is a trending security notion of dynamic searchable symmetric encryption (DSSE). It guarantees the privacy of newly added data against the server who has knowledge of previous queries. The notion was very recently formalized by Bost (CCS ’16) independently, yet the definition given is imprecise to capture how forward secure a scheme is. We further the study of forward privacy by...
