An Efficient and Secure Public Key Authenticated Encryption With Keyword Search in the Logarithmic Time

open access: yesIEEE Access, 2021
Searchable encryption is an important cryptographic technique that achieves data security and keyword retrieval over encrypted data in cloud. In 2004, Boneh et.al proposed the first searchable encryption scheme based on asymmetric cryptography.

Multi-key Fully Homomorphic Encryption from Additive Homomorphism

open access: yesThe Computer Journal, 2021
Abstract Fully homomorphic encryption (FHE) allows direct computations over the encrypted data without access to the decryption. Hence multi-key FHE is well suitable for secure multiparty computation. Recently, Brakerski et al. (TCC 2019 and EUROCRYPT 2020) utilized additively homomorphic encryption to construct FHE schemes with ...

An improved secure designated server public key searchable encryption scheme with multi-ciphertext indistinguishability

open access: yesJournal of Cloud Computing: Advances, Systems and Applications, 2022
In the cloud, users prefer to store their sensitive data in encrypted form. Searching keywords over encrypted data without loss of data confidentiality is an important issue. In 2004, Boneh et al.

Quantum Indistinguishability for Public Key Encryption [PDF]

open access: yes, 2021
In this work we study the quantum security of public key encryption schemes (PKE). Boneh and Zhandry (CRYPTO\u2713) initiated this research area for PKE and symmetric key encryption (SKE), albeit restricted to a classical indistinguishability phase ...
