Public Key Encryption with Keyword Search 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...
Public key Encryption with Keyword Search (PEKS) schemes offer encrypted search functionality to mitigate the impacts of privacy versus data utilization dilemma. PEKS schemes allow any client to encrypt their data under a public key such that the cloud, using the corresponding trapdoor, can later ...
The present principle relate to new public-key cryptosystems with searchable encryption, in particular, public key encryption with keyword search. Public key encryption with keyword search is a form of encryption that allows searching on data that is encrypted using a public key system. Notably, the...
Abstract—Cloud-assisted Industrial Internet of Things (IIoT) relies on cloud computing to provide massive data storage services. To ensure the confidentiality, sensitive industrial data need to be encrypted before being outsourced to cloud storage server. Public-key encryption with keyword search (PEKS...
摘要: Public-keyword encryption with keyword search (PEKS) is a newly emerged primitive which can provide data search functionality that is absent in traditional public-key encryption (PKE). In this work, we propose the first provably secure PEKS from lattice.关键词:...
Public key encryption with keyword search (PKES) enables senders to send encrypted data to a Freceiver like traditional public key encryption (PKE) schemes. The difference between PKES and PKE is that the receiver in PKES can search on the encrypted data which is stored on the third-party ser...
A public key encryption scheme with keyword search capabilities is proposed using lattices for applications in multiuser environments. The proposed scheme enables a cloud server to check if any given encrypted data contains certain keywords specified by multiple users, but the server would not have ...

We study the problem of a public key encryption with conjunctive keyword search (PECK). The keyword searchable encryption enables a user to outsource his data to the storage of an untrusted server and to have the ability to selectively search his data wi
Aiming at the problems of great computation of pairings in Public key Encryption with Keyword Search(PEKS) schemes are still time consuming and inefficient, and the proposed PEKS schemes can not resist to relay attacks, on the base of researching the PEKS, this paper proposes a more efficient ...
