Attribute-based keyword search encryption for power data protection
High-Confidence Computing, 2023 To protect the privacy of power data, we usually encrypt data before outsourcing it to the cloud servers. However, it is challenging to search over the encrypted data. In addition, we need to ensure that only authorized users can retrieve the power data.

Hybrid keyword search auctions
Proceedings of the 18th international conference on World wide web, 2009 Search auctions have become a dominant source of revenue generation on the Internet. Such auctions have typically used per-click bidding and pricing. We propose the use of hybrid auctions where an advertiser can make a per-impression as well as a per-click bid, and the auctioneer then chooses one of the two as the pricing mechanism.

Public-Key Encryption With Keyword Search via Obfuscation
IEEE Access, 2019 Public-key encryption with keyword search (PEKS) enables users to search on encrypted data, which is applicable to the scenario of sharing data in the cloud storage. In this paper, we focus on how to construct a PEKS scheme via obfuscation.
