Secure Conjunctive Keyword Search over Encrypted Data
We study the setting in which a user stores encrypted documents (e.g. e-mails) on an untrusted server. In order to retrieve documents satisfying a certain search criterion, the user gives the server a capability that allows the server to identify exactly those documents. Work in this area has largely focused on search criteria consisting of a single keyword. If the user is actually interested i...
متن کاملOblivious Conjunctive Keyword Search
We study the problem of keyword search in which a server contains various multimedia contents and a user of server wishes to retrieve some multimedia item containing specific keywords without revealing to the server which item it is. Recently, Ogata and Kurosawa introduced an interesting keyword search scheme called oblivious keyword search by using the notion of oblivious transfer. However, on...
متن کاملSecure Data Storage Outsourcing with Conjunctive Keyword Search
This thesis in the field of cryptography considers secure data outsourcing with keyword search capabilities. To ensure data confidentiality the data is stored in encrypted format. An efficient solution has been developed to enable conjunctive keyword search. Also, a protocol is applied to enable efficient and secure sharing of encrypted data. It is possible to efficiently enrol and revoke users...
متن کاملPublic Key Encryption with Conjunctive Field Free Keyword Search Scheme
Searchable encryption allows a remote server to search over encrypted documents without knowing the sensitive data contents. Prior searchable symmetric encryption schemes focus on single keyword search. Conjunctive Keyword Searches (CKS) schemes improve system usability by retrieving the matched documents. In this type of search, the user has to repeatedly perform the search protocol for many t...
متن کاملConjunctive Fuzzy Keyword Search Over Encrypted Data in Cloud Computing
As Cloud Computing becomes prevalent, more and more sensitive information are centralized into the cloud. For the protect data privacy, sensitive data usually have to be encrypted before outsourcing, which makes efficient data utilization a very challenging task. Although traditional searchable encryption schemes allow a user to search over encrypted data through keywords and selectively retrie...
