SHARD: cell-keyed residual splitting for alignment-resistant private dense retrieval
Sergey Kurilenko
The paper introduces SHARD, a technique that divides PCA‑derived document vectors into a short public prefix and a residual encrypted with cell‑specific orthogonal keys, aiming to…

Hybrid privacy-aware semantic search: SVD-truncated document geometry and CKKS-encrypted query reranking under a restricted threat model
Sergey Kurilenko
The paper proposes a hybrid semantic search system that uses a public SVD‑based document representation and client‑side candidate selection, while encrypting the query with the CKK…
