SPEKS: Forward Private SGX-Based Public Key Encryption with Keyword Search
Applied Sciences, 2020 Public key encryption with keyword search (PEKS) enables users to search over encrypted data outsourced to an untrusted server. Unfortunately, updates to the outsourced data may incur information leakage by exploiting the previously submitted queries ...

A Survey on Public Key Encryption with Keyword Search: Taxonomy and Methods
International Journal of Mathematics and Mathematical Sciences, 2022 Given the many benefits that cloud computing brings, organizations tend to outsource most of their data to reduce a large portion of their costs, but concern about the privacy of data is a major obstacle to outsourcing sensitive data.

Tree-Based Public Key Encryption with Conjunctive Keyword Search [PDF]
Security and Communication Networks, 2021 Searchable public key encryption supporting conjunctive keyword search is an important technique in today’s cloud environment. Nowadays, previous schemes usually take advantage of forward index structure, which leads to a linear search complexity. In order to obtain better search efficiency, in this paper, we utilize a tree index structure instead of ...

Towards efficient verifiable multi-keyword search over encrypted data based on blockchain [PDF]
PeerJ Computer Science, 2022 Searchable symmetric encryption (SSE) provides an effective way to search encrypted data stored on untrusted servers. When the server is not trusted, it is indispensable to verify the results returned by it.

Public Key Encryption with Keyword Search [PDF]
, 2004 We study the problem of searching on data that is encrypted using a public key system. Consider user Bob who sends email to user Alice encrypted under Alice’s public key. An email gateway wants to test whether the email contains the keyword “urgent” so that it could route the email accordingly. Alice, on the other hand does not wish to give the gateway

Combining Public Key Encryption with Keyword Search and Public Key Encryption
IEICE Transactions on Information and Systems, 2009 In this paper, we study the problem of secure integrating public key encryption with keyword search (PEKS) with public key data encryption (PKE). We argue the previous security model is not complete regarding keyword privacy and the previous constructions are secure only in the random oracle model.
