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)

Efficient public key encryption with revocable keyword search
Security and Communication Networks, 2013 ABSTRACTPublic key encryption with keyword search is a novel cryptographic primitive enabling one to search on the encrypted data directly. In the known schemes, once getting a trapdoor, the server can search associated data without any restrictions. However, in reality, it is sometimes essential to prevent the server from searching the data all the ...

Certificate-Based Encryption with Keyword Search: Enabling Secure Authorization in Electronic Health Record [PDF]
Journal of Internet Services and Information Security, 2016 In an e-Health scenario, we study how the practitioners are authorized when they are requesting access to medical documents containing sensitive information. Consider the following scenario. A clinician wants to access and retrieve a patient’s Electronic
