Certificateless Searchable Encryption Scheme in Multi-User Environment
Cryptography, 2022 Searchable encryption technology enables users to access data that has been made publicly encrypted without divulging the original content. The majority of the currently available multi-user certificateless searchable encryption technologies are based on

New leakage-resilient CCA-secure public key encryption
Journal of Mathematical Cryptology, 2013 This paper shows a generic method of constructing CCA-secure public key encryption schemes with leakage-resilience on the secret key. It is based on a new kind of universal2 hash proof system which accepts an auxiliary parameter.

A New Technique in Rank Metric Code-Based Encryption
Cryptography, 2018 We propose a rank metric codes based encryption based on the hard problem of rank syndrome decoding problem. We propose a new encryption with a public key matrix by considering the adding of a random distortion matrix over F q m of full column ...

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 ...

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.

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

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.

Certificate-based hybrid encryption scheme in the standard model
Tongxin xuebao, 2009 For construction a public cryptosystem that requiring fewer infrastructures than public key infrastructure（PKI）,a certificate-based public-key encryption（CBE） scheme was proposed by Gentry.In CBE scheme,a certification was signed by a third part on an ...
