Searchable Encryption in Cloud Storage
Cloud outsource storage is one of important services in cloud computing. Cloud users upload data to cloud servers to reduce the cost of managing data and maintaining hardware and software. To ensure data confidentiality, users can encrypt their files before uploading them to a cloud system. However, retrieving the target file from the encrypted files exactly is difficult for cloud server. This ...
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...
متن کاملEfficient Attribute-Based Searchable Encryption on the Cloud Storage
Cloud computing is very popular for its computing and storage capacity at lower cost. More and more data are being moved to the cloud to reduce storage cost. On the other hand, since the cloud is not fully trustable, in order to protect data privacy against third-parties and even the cloud server, they are usually encrypted before uploading. However, many operations, such as searching, are hard...
متن کاملMuSE: Multimodal Searchable Encryption for Cloud Applications
In this paper we tackle the practical challenges of searching encrypted multimodal data (i.e. data containing multiple media formats), stored in public cloud servers, with minimal information leakage. To this end we propose MuSE, a Multimodal Searchable Encryption scheme that, by combining only standard cryptographic primitives and symmetric-key block ciphers, allows cloud-backed applications t...
متن کاملA High-Security Searchable Encryption Framework for Privacy-Critical Cloud Storage Services
Searchable encryption has received a signi cant attention from the research community with various constructions being proposed, each achieving asymptotically optimal complexity for speci c metrics (e.g., search, update). Despite their elegancy, the recent attacks and deployment e orts have shown that the optimal asymptotic complexity might not always imply practical performance, especially if ...
