Efficient multi-keyword search over p2p web

Proceedings of the 17th international conference on World Wide Web, 2008
Current search mechanisms of DHT-based P2P systems can well handle a single keyword search problem. Other than single keyword search, multi-keyword search is quite popular and useful in many real applications. Simply using the solution for single keyword search will require distributed intersection/union operations in wide area networks, leading to ...

Heavy-tailed distributions and multi-keyword queries

Proceedings of the 30th annual international ACM SIGIR conference on Research and development in information retrieval, 2007
Intersecting inverted indexes is a fundamental operation for many applications in information retrieval and databases. Efficient indexing for this operation is known to be a hard problem for arbitrary data distributions. However, text corpora used in Information Retrieval applications often have convenient power-law constraints (also known as Zipf's ...

Multi-keyword ranked searchable public-key encryption

International Journal of Grid and Utility Computing, 2015
Most related works on Public-Key Encryption with Keyword Search scheme also called Searchable Public-key Encryption focus on single keyword search. Some works supporting multi-keyword search cannot provide search result ranking. In this paper, we study the problem of multi-keyword ranked search over encrypted data in public-key model.

Attribute-Based Encryption with Multi-keyword Search

2017 IEEE Second International Conference on Data Science in Cyberspace (DSC), 2017
Public key encryption with keyword search applies only to the certain circumstances that keyword ciphertext can only be retrieved by a specific user and only supports single-keyword matching. In the existing searchable encryption schemes, either the communication mode is one-to-one, or only single-keyword search is supported.

Ranked multi-keyword search data using cloud

2017 International Conference on Inventive Computing and Informatics (ICICI), 2017
Along with the tremendous implementation of cloud technologies for common person for free, data creators and owners are compelled to shift or outsource their tedious data handling and management systems from self-owned local data storage and management sites to the commercial and easy to use public cloud for fast and speedy data access mechanism and ...

Efficient forward secure searchable encryption supporting multi-keyword query

The 2nd International Conference on Computing and Data Science, 2021
Searchable encryption (SE) allows client to outsource personal data to an untrusted server while protecting the data privacy, which is widely used by corporations and individuals. Recently, many works show that forward privacy is the fundamental property for secure SE cryptosystem, and several forward secure SE schemes have been proposed. However, most
