Registered FE beyond predicates:(attribute-based) linear functions and more
This paper introduces the first registered functional encryption RFE scheme tailored for
linear functions. Distinctly different from classical functional encryption (FE), RFE addresses …

Fine-grained polynomial functional encryption
Z Zhu, J Gong, Y Wang, H Qian - Theoretical Computer Science, 2024 - Elsevier
In this work, we present fine-grained secure polynomial functional encryption (PFE) for
degree d≥ 1 over a field F: a ciphertext encrypts x∈ F n, a key is associated with a degree-d …
