Leveled Certificateless Fully Homomorphic Encryption Schemes From Learning With Errors

IEEE Access, 2020
Fully homomorphic encryption (FHE) is a form of public-key encryption that allows the computation of arbitrary functions on encrypted data without decrypting the data. As a result, it is a useful tool with numerous applications.

FS-PEKS: Lattice-Based Forward Secure Public-Key Encryption with Keyword Search for Cloud-Assisted Industrial Internet of Things

IEEE Transactions on Dependable and Secure Computing, 2019
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.

Survey on public key encryption with equality test

网络与信息安全学报, 2018
As one of the important methods of solving the problem of computation over encrypted data under multiple public keys in cloud environment,public key encryption with equality test (PKEET) supports to check whether two ciphertexts encrypted under (possibly)

CCA-Secure Deterministic Identity-Based Encryption Scheme [PDF]

Journal of Universal Computer Science, 2019
Deterministic public-key encryption, encrypting a plaintext into a unique ciphertext without involving any randomness, was introduced by Bellare, Boldyreva, and O'Neill (CRYPTO 2007) as a realistic alternative to some inherent drawbacks in randomized ...

Provably sender-deniable encryption scheme [PDF]

Computer Science Journal of Moldova, 2015
The use of the well known provably secure public-key cryptoscheme by Rabin is extended for the case of the deniable encryption. In the proposed new sender-deniable encryption scheme the cryptogram is computed as coefficients of quadratic congruence, the

A CCA2 Secure Variant of the McEliece Cryptosystem [PDF]

, 2012
The McEliece public-key encryption scheme has become an interesting alternative to cryptosystems based on number-theoretical problems. Differently from RSA and ElGa- mal, McEliece PKC is not known to be broken by a quantum computer.

Public Key Image Encryption Based on Compressed Sensing

IEEE Access, 2019
The compression feature of compressed sensing (CS) enables that the ciphertext lengths of multimedia encryption schemes have reduced dramatically, and the simple linear measurements make the encryption process extremely efficient.
