Fuzzy Keywords enabled Ranked Searchable Encryption Scheme for a Public Cloud Environment

Shahzaib Tahir, Sushmita Ruj, Ali Sajjad, Muttukrishnan Rajarajan
2018 Computer Communications  
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.  ...

Efficient Regular Language Search for Secure Cloud Storage

Karthikeyan B, Vishaal S, Ajithkumar P
2019 IJARCCE  
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  ...  Public-Key Encryption with Fuzzy Keyword Search: A Provably Secure Scheme under Keyword Guessing Attack This paper studies to avoid keyword guessing attack.  ...

Searching on Encrypted E-Data Using Random Searchable Encryption (RanSCrypt) Scheme

M Ahsan, Mohd Idna Bin Idris, Ainuddin Bin Abdul Wahab, Ihsan Ali, Nawsher Khan, Mohammed Al-Garwi, Atiq Rahman
2018 Symmetry  
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.  ...  We used Request for Comments database (RFC) similar to Fu et al.'s scheme [37] .  ...

A Survey of Provably Secure Searchable Encryption

Christoph Bösch, Pieter Hartel, Willem Jonker, Andreas Peter
2014 ACM Computing Surveys  
We survey the notion of provably secure searchable encryption (SE) by giving a complete and comprehensive overview of the two main SE techniques: searchable symmetric encryption (SSE) and public key encryption  ...  In a public key encryption (PKE) scheme, the private key decrypts all messages encrypted under the corresponding public key.  ...  Fuzzy search using Edit distance.  ...

Efficient Data Retrieval and Fine Grained Access Control on Secure Hybrid Cloud

2020 International Journal of Emerging Trends in Engineering Research  
Hybrid cloud is a model which is a combination of both private and public clouds. This model is proposed as a way of storing healthcare data.  ...  The retrieval data passed from cloud to user end is masked with simple transformation.  ...  Fuzzy keyword search, in addition to fine grained access control scheme, is proposed over encrypted data.  ...

Identification with Encrypted Biometric Data [article]

Julien Bringer, Herve Chabanne, Bruno Kindarji
2009 arXiv   pre-print
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.  ...

Query-Biased Preview over Outsourced and Encrypted Data

Ningduo Peng, Guangchun Luo, Ke Qin, Aiguo Chen
2013 The Scientific World Journal  
Based on private information retrieval protocol and the core concept of searchable encryption, we propose a single-server and two-round solution to securely obtain a query-biased snippet over the encrypted  ...  A generalization for symmetric searchable encryption was introduced in [12] . Another type of searchable encryption schemes is public-key based.  ...  References [20] [21] [22] introduced fuzzy keyword search over encrypted data. Similar to fuzzy keyword search but different, [23, 24] introduced similarity search over encrypted data.  ...

Privacy-Preserving and Regular Language Search Over Encrypted Cloud Data

Kaitai Liang, Xinyi Huang, Fuchun Guo, Joseph K. Liu
2016 IEEE Transactions on Information Forensics and Security  
Our security and performance analysis show that the proposed system is provably secure and more efficient than some public key searchable systems with high expressiveness.  ...  A major advantage of our new primitive compared to the existing public key based search systems is that it supports an extreme expressive search mode, regular language search.  ...  Most of existing public key based searchable encryption cannot hold against offiline keyword-guessing attacks.  ...

Text Retrieval Online: Historical Perspective on Web Search Engines

Trudi Bellardo Hahn
2005 Bulletin of the American Society for Information Science and Technology  
Search Capabilities The goal of a search capability is to match a user's specified information need with items in a database that will answer it.  ...  It is worth noting also that many of these search features had been conceptualized a decade or so earlier and used in serial searching of databases on magnetic tape.  ...  Elimination of stop words speeds retrieval by making some words not searchable.  ...
