Experimental Demonstration of Quantum Fully Homomorphic Encryption with Application in a Two-Party Secure Protocol [PDF]
Physical Review X, 2020 A fully homomorphic encryption system hides data from unauthorized parties while still allowing them to perform computations on the encrypted data. Aside from the straightforward benefit of allowing users to delegate computations to a more powerful ...

Secure Fully Homomorphic Authenticated Encryption
IEEE Access, 2021 Homomorphic authenticated encryption allows implicit computation on plaintexts using corresponding ciphertexts without losing privacy, and provides authenticity of the computation and the resultant plaintext of the computation when performing a ...

Potential of Homomorphic Encryption for Cloud Computing Use Cases in Manufacturing
Journal of Cybersecurity and Privacy, 2023 Homomorphic encryption enables secure cloud computing over the complete data lifecycle. As so-called in-use encryption methodology, it allows using encrypted data for, e.g., data analysis—in contrast to classic encryption methods.

Homomorphic-Encrypted Volume Rendering [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2021 Computationally demanding tasks are typically calculated in dedicated data centers, and real-time visualizations also follow this trend. Some rendering tasks, however, require the highest level of confidentiality so that no other party, besides the owner, can read or see the sensitive data.

Experimental quantum homomorphic encryption [PDF]
npj Quantum Information, 2021 AbstractQuantum computers promise not only to outperform classical machines for certain important tasks, but also to preserve privacy of computation. For example, the blind quantum computing protocol enables secure delegated quantum computation, where a client can protect the privacy of their data and algorithms from a quantum server assigned to run ...

NTRU-type fully homomorphic encryption scheme without key switching
网络与信息安全学报, 2017 In order to construct a fully homomorphic encryption scheme based on NTRU cryptosystem from ring learning with errors, noise growth and homomorphic property in the NTRU cryptosystem were analyzed. The con-cept of zero homomorphic encryption was introdced

Research on privacy information retrieval model based on hybrid homomorphic encryption
Cybersecurity, 2023 The computational complexity of privacy information retrieval protocols is often linearly related to database size. When the database size is large, the efficiency of privacy information retrieval protocols is relatively low.
