Multiple to One Fully Homomorphic Encryption Algorithm Based on Integer Polynomial Ring [PDF]
Jisuanji gongcheng, 2019 Aiming at the limitation that most traditional public key encryption mode can only send messages from a single sender to a single receiver,a one to one homomorphic encryption algorithm based on integer polynomial ring is designed based on integer ...

Modified Multi-Key Fully Homomorphic Encryption Scheme in the Plain Model
The Computer Journal, 2022 Abstract Multi-key fully homomorphic encryption (MFHE) supports arbitrary meaningful computations on encrypted data under different public keys even without access to the secret key, which is well tailored for the secure multiparty computation scenarios.

Multi-Key Homomorphic Encryption from TFHE
, 2019 In this paper, we propose a Multi-Key Homomorphic Encryption (MKHE) scheme by generalizing the low-latency homomorphic encryption by Chillotti et al. (ASIACRYPT 2016). Our scheme can evaluate a binary gate on ciphertexts encrypted under different keys followed by a bootstrapping.

Practical identity-based key agreement for secure communication in sensor networks [PDF]
, 2009 Despite much research effort key distribution in Wireless Sensor Networks (WSNs) still remains an open problem. In this paper we address this issue by proposing a simple identity- based key agreement scheme. Our protocol uses Identity-Based Cryptography (

Multi-authority Attribute-based Encryption Scheme with Policy Hiding [PDF]
Jisuanji gongcheng, 2018 Most existing attribute-based encryption schemes of hidden policies are directed to a single authority,without taking into account the situation where the users’ attributes are managed by multi-authority,having the problems such as low-efficient of key ...

Multi-Instance Secure Public-Key Encryption [PDF]
, 2023 Mass surveillance targets many users at the same time with the goal of learning as much as possible. Intuitively, breaking many users’ cryptography simultaneously should be at least as hard as that of only breaking a single one, but ideally security ...
