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 acc...
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...
Public-key encryption with keyword search (PEKS) enables users to search on encrypted data which is applicable to scenario of sharing data in the cloud storage. The existing PEKS schemes fail to verify the returned result from the tester, i.e. they cannot guarantee the correctness and completene...
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...
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...
However, most schemes only support single-keyword search and do not support file updates, which limit the flexibility of the scheme. To eliminate these problems, we propose a blockchain-enabled public key encryption scheme with multi-keyword search (BPKEMS), and our scheme supports file updates....
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:...
This is a scenario where public key encryption with keyword search (PEKS) is needed. In this paper we construct a new scheme (KR-PEKS) the K-Resilient Public Key Encryption with Keyword Search. The new scheme is secure under a chosen keyword attack without the random oracle. The abilit...
The notion of Public-key Encryption with Keyword Search (PEKS) was first proposed by Boneh et al. in 2004. However, almost all PEKS schemes cannot resist offline Keyword Guessing Attacks (KGA). To address this issue, Huang and Li introduced the notion of Public-key Authenticated Encryption wi...
Public key encryption with keyword search (PEKS) technology is capable of achieving accurate ciphertext retrieval while protecting data privacy. However, curious or malicious semi-trusted cloud servers can cause privacy breaches, which then creates a trust problem for ciphertext management and searching...
