Fuzzy Keywords enabled Ranked Searchable Encryption Scheme for a Public Cloud Environment
2018
Computer Communications
Preserved Fulltext
This paper presents a novel ranked searchable encryption scheme that addresses this issue by supporting fuzzy keywords. ...
The proposed construction is deployed on the British Telecommunication's public Cloud architecture and evaluated over a real-life speech corpus. ...
It may be observed that the proposed scheme does not require a relational database, therefore, the masking function can be strengthened by using OPE. ...

Searchable encryption could provide the functions of confidentiality protection and privacy-preserving data retrieval, which is an important tool for secure storage. ...
So they propose a novel concept called public-key encryption with fuzzy keyword search (PEFKS), by which the un-trusted server only obtains the fuzzy search trapdoor instead of the exact search trapdoor ...

Abstract: Cloud computing is intensifying the necessity for searchable encryption (SE) for data protection in cloud storage. ...
However, due to the smaller size of the keyword space, SEs using a public key are susceptible to a Keyword Guessing Attack (KGA) and other statistical information leakage. ...

This is the first non-trivial identification scheme dealing with fuzziness and encrypted data. ...
Biometrics make human identification possible with a sample of a biometric trait and an associated database. Classical identification techniques lead to privacy concerns. ...
For that purpose, we need to find a way to: • mitigate the effects of biometrics fuzziness, • and efficiently identify someone over an encrypted database. ...
