Searchable encryption
We built a system supporting encrypted substring search of a text document. The user can encrypt and upload files to a server. The client can also query the server to ask whether an encrypted file contains a particular string of characters. The query, like the file, is not sent in plaintext but is encrypted or hashed. The server should be able to respond correctly to queries without learning th...
متن کاملSearchable Encryption for Outsourced Data Analytics
Two sets of privacy requirements need to be fulfilled when a company’s accounting data is audited by an external party: the company needs to safeguard its data, while the auditors do not want to reveal their investigation methods. This problem is usually addressed by physically isolating data and auditors during the course of an audit. This approach however no longer works when auditing is perf...
متن کاملBrowse searchable encryption schemes: Classification, methods and recent developments
With the advent of cloud computing, data owners tend to submit their data to cloud servers and allow users to access data when needed. However, outsourcing sensitive data will lead to privacy issues. Encrypting data before outsourcing solves privacy issues, but in this case, we will lose the ability to search the data. Searchable encryption (SE) schemes have been proposed to achieve this featur...
متن کاملGarbled Searchable Symmetric Encryption
In a searchable symmetric encryption (SSE) scheme, a client can keyword search over symmetrically-encrypted files which he stored on the server (ideally without leaking any information to the server). In this paper, we show the first multiple keyword search SSE scheme such that even the search formula f (AND, OR and so on) is kept secret. Our scheme is based on an extended garbled circuit satis...
متن کاملMulti-Key Searchable Encryption
We construct a searchable encryption scheme that enables keyword search over data encrypted with different keys. The scheme is practical and was designed to be included in a new system for protecting data confidentiality in client-server applications against attacks on the server.
