Bootstrapping as a Morphism: An Arithmetic Geometry Approach to Asymptotically Faster Homomorphic Encryption
Dongfang Zhao
Fully Homomorphic Encryption (FHE) provides a powerful paradigm for secure computation, but its practical adoption is severely hindered by the prohibitive computational cost of its…
Balancing Privacy and Efficiency: Music Information Retrieval via Additive Homomorphic Encryption
William Zerong Wang, Dongfang Zhao
Modern music retrieval runs on vector embeddings, and once these embeddings are shared for search or matching they can be copied, probed, or used to train generative models. Fully…
Hermes: Efficient Global Homomorphic Aggregation over Mutable Packed Ciphertexts
Dongfang Zhao
Fully Homomorphic Encryption (FHE) promises the ability to compute over encrypted data without revealing sensitive contents. However, enabling high-frequency updates and statistica…
Compile-Time Fully Homomorphic Encryption of Vectors: Eliminating Online Encryption via Algebraic Basis Synthesis
Dongfang Zhao
We propose a framework for compile-time ciphertext synthesis in fully homomorphic encryption (FHE) systems, where ciphertexts are constructed from precomputed encrypted basis vecto…
A Note on Efficient Privacy-Preserving Similarity Search for Encrypted Vectors
Dongfang Zhao
Traditional approaches to vector similarity search over encrypted data rely on fully homomorphic encryption (FHE) to enable computation without decryption. However, the substantial…
VLWE: Variety-based Learning with Errors for Vector Encryption through Algebraic Geometry
Dongfang Zhao
Lattice-based cryptography is a foundation for post-quantum security, with the Learning with Errors (LWE) problem as a core component in key exchange, encryption, and homomorphic c…
Hades: Homomorphic Augmented Decryption for Efficient Symbol-comparison -- A Database's Perspective
Dongfang Zhao
Outsourced databases powered by fully homomorphic encryption (FHE) offer the promise of secure data processing on untrusted cloud servers. A crucial aspect of database functionalit…
HOPE: Homomorphic Order-Preserving Encryption for Outsourced Databases -- A Stateless Approach
Baiqiang Wang, Dongfang Zhao
