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 کاملCorrelation-Resistant Storage via Keyword-Searchable Encryption
We consider the problem of using untrusted components to build correlation-resistant survivable storage systems that protect file replica locations, while allowing nodes to continuously re-distribute files throughout the network. The principal contribution is a chosen-ciphertext secure, searchable public key encryption scheme which allows for dynamic re-encryption of ciphertexts, and provides f...
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 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 کاملKey Aggregate Searchable Encryption for Group Data Sharing Via Cloud Data Storage
the ability of preferentially sharing encrypted data with unlike users through public cloud storage might really ease security distress, by possibility data disclose in the cloud. A key test to design such encryption idea lies in the well-organized management encryption keys. The preferred flexibility of allocating any group documents with any group of users by attaining weightage different enc...
