Inner product encryption from ring learning with errors

open access: yesCybersecurity, 2020
The functional encryption scheme designed using the lattice can realize fine-grained encryption and it can resist quantum attacks. Unfortunately, the sizes of the keys and ciphertexts in cryptographic applications based on learning with errors are large,

Efficient Multi-Client Functional Encryption for Conjunctive Equality and Range Queries

open access: yesIEEE Access, 2022
In multi-client functional encryption (MC-FE) for predicate queries, clients generate ciphertexts of plaintexts $x_{1}, \ldots, x_{n}$ binding with a time period $T$ and store them on a cloud server, and the cloud server receives a function key ...

Certified Everlasting Functional Encryption

open access: yesIACR Cryptol. ePrint Arch., 2022
Computational security in cryptography has a risk that computational assumptions underlying the security are broken in the future. One solution is to construct information-theoretically-secure protocols, but many cryptographic primitives are known to be impossible (or unlikely) to have information-theoretical security even in the quantum world.

Fuzzy Keyword Searchable Encryption Scheme Based on Blockchain

open access: yesInformation, 2022
Searchable encryption is a keyword-based ciphertext retrieval scheme, which can selectively retrieve encrypted documents on encrypted cloud data. Most existing searchable encryption schemes focus only on exact keyword searches and cannot return data of ...

Public Trace-and-Revoke Proxy Re-encryption

open access: yes, 2022
Proxy re-encryption (PRE), as a promising cryptographic primitive for secure data sharing in cloud, has been widely studied for decades. PRE allows the proxies to use the re-encryption keys to convert ciphertexts computed under the delegator’s public key
