Research on the searchable encryption
网络与信息安全学报, 2016 Searchable encryption has been recognized as a promising method to achieve the secure cloud search.According to the types of encryption keys,searchable encryption can be divided into searchable public-key and symmetric-key encryptions.The existing and ...

Combining Public Key Encryption with Keyword Search and Public Key Encryption
IEICE Transactions on Information and Systems, 2009 In this paper, we study the problem of secure integrating public key encryption with keyword search (PEKS) with public key data encryption (PKE). We argue the previous security model is not complete regarding keyword privacy and the previous constructions are secure only in the random oracle model.

Lattice-based certificateless public-key encryption in the standard model [PDF]
, 2013 The notion of certificateless public-key encryption (CL-PKE) was introduced by Al-Riyami and Paterson in 2003 that avoids the drawbacks of both traditional PKI-based public-key encryption (i.e., establishing public-key infrastructure) and identity-based ...

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

Parallel authentication and public-key encryption [PDF]
, 2003 A parallel authentication and public-key encryption is introduced and exemplified on joint encryption and signing which compares favorably with sequential Encrypt-then-Sign (ɛtS) or Sign-then-Encrypt (Stɛ) schemes as far as both efficiency and security ...

Public Trace-and-Revoke Proxy Re-encryption [PDF]
, 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

An Efficient RSA Public Key Encryption Scheme [PDF]
, 2008 In this paper, we propose an efficient RSA public key encryption scheme, which is an improved version of original RSA scheme. The proposed RSA encryption scheme is based on linear group over the ring of integer mod a composite modulus n which is the ...

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.

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)

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 ...
