Multi-user Searchable Encryption in the Cloud
While Searchable Encryption (SE) has been widely studied, adapting it to the multi-user setting whereby many users can upload secret files or documents and delegate search operations to multiple other users still remains an interesting problem. In this paper we show that the adversarial models used in existing multi-user searchable encryption solutions are not realistic as they implicitly requi...
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 کاملA Searchable Symmetric Encryption Scheme using BlockChain
At present, the cloud storage used in searchable symmetric encryption schemes (SSE) is provided in a private way, which cannot be seen as a true cloud. Moreover, the cloud server is thought to be credible, because it always returns the search result to the user, even they are not correct. In order to really resist this malicious adversary and accelerate the usage of the data, it is necessary to...
متن کاملMulti-level Searchable Symmetric Encryption
Remote storage delivers a cost effective solution for data storage. If data is of a sensitive nature, it should be encrypted prior to outsourcing to ensure confidentiality; however, searching then becomes challenging. Searchable encryption is a well-studied solution to this problem. Many schemes only consider the scenario where users can search over the entirety of the encrypted data. In practi...
متن کاملA multi-user searchable encryption scheme with keyword authorization in a cloud storage
Multi-user searchable encryption (MSE) allows a user to encrypt its files in such a way that these files can be searched by other users that have been authorized by the user. The most immediate application of MSE is to cloud storage, where it enables a user to securely outsource its files to an untrusted cloud storage provider without sacrificing the ability to share and search over it. Any pra...
