Efficient Dynamic Searchable Encryption with Forward Privacy
Searchable symmetric encryption (SSE) enables a client to perform searches over its outsourced encrypted files while preserving privacy of the files and queries. Dynamic schemes, where files can be added or removed, leak more information than static schemes. For dynamic schemes, forward privacy requires that a newly added file cannot be linked to previous searches. We present a new dynamic SSE ...
متن کاملForward-Private Dynamic Searchable Symmetric Encryption with Efficient Search
Dynamic Searchable Symmetric Encryption (DSSE) allows to delegate keyword search and le update over an encrypted database via encrypted indexes, and therefore provides opportunities to mitigate the data privacy and utilization dilemma in cloud storage platforms. Despite its merits, recent works have shown that e cient DSSE schemes are vulnerable to statistical attacks due to the lack of forward...
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 کاملVerifiable Dynamic Symmetric Searchable Encryption: Optimality and Forward Security
Symmetric Searchable Encryption (SSE) is a very efficient and practical way for data owners to outsource storage of a database to a server while providing privacy guarantees. Such SSE schemes enable clients to encrypt their database while still performing queries for retrieving documents matching some keyword. This functionality is interesting to secure cloud storage, and efficient schemes have...
متن کاملAn Efficient Symmetric Searchable Encryption Scheme for Cloud Storage
Symmetric searchable encryption for cloud storage enables users to retrieve the documents they want in a privacy-preserving way, which has become a hotspot of research. In this paper, we propose an efficient keyword search scheme over encrypted cloud data. We firstly adopt a structure named as inverted matrix (IM) to build search index. The IM is consisted of index vectors, each of which is ass...
