Threshold encryption with silent setup
We build a concretely efficient threshold encryption scheme where the joint public key of a
set of parties is computed as a deterministic function of their locally computed public keys …

Reducing the CRS size in registered ABE systems
Attribute-based encryption (ABE) is a generalization of public-key encryption that enables
fine-grained access control to encrypted data. In (ciphertext-policy) ABE, a central trusted …
