Triple receiver public key encryption cryptosystem

网络与信息安全学报, 2020
A triple receiver public key cryptosystem was proposed. In the cryptosystem, a sender encrypted a message and sent to three receivers, while the three receivers were able to decrypt the message with their own private keys.

Public-Key Encryption With Keyword Search via Obfuscation [PDF]

IEEE Access, 2019
Public-key encryption with keyword search (PEKS) enables users to search on encrypted data, which is applicable to the scenario of sharing data in the cloud storage. In this paper, we focus on how to construct a PEKS scheme via obfuscation.

On Multiple Encryption for Public-Key Cryptography

Cryptography, 2023
Using multiple, individual encryption schemes is a well-established method to increase the overall security of encrypted data. These so-called multiple encryption or hybrid schemes have regained traction in the context of public-key cryptography due to ...

Public-Key Encryption Secure Against Related Randomness Attacks for Improved End-to-End Security of Cloud/Edge Computing

IEEE Access, 2020
Public-key encryption is often used to protect data security/privacy and secure communication in scenarios of cloud computing and edge computing. Related randomness attacks model (RRA) for public-key encryption was motivated by randomness failures.
