Functional Encryption with Bounded Collusions via Multi-party Computation
We construct a functional encryption scheme secure against an a-priori bounded polynomial number of collusions for the class of all polynomial-size circuits. Our constructions req...

Multi-party Indirect Indexing and Applications
Abstract. We develop a new multi-party generalization of Naor-Nissim indirect indexing, making it possible for many participants to simulate a RAM machine with only poly-logarithmi...

Multiparty Computation with Low Communication, Computation and Interaction via Threshold FHE
Fully homomorphic encryption (FHE) provides a simple template for secure computation between two parties (Alice and Bob) where: (I) Alice encrypts her input under her key, (II) Bo...

Secure Multiparty AES
Abstract We propose several variants of a secure multiparty computation protocol for AES encryption. The best variant requires 2200 + 400 255 expected elementary operations in expe...

Semi-homomorphic Encryption and Multiparty Computation
An additively-homomorphic encryption scheme enables us to compute linear functions of an encrypted input by manipulating only the ciphertexts. We define the relaxed notion of a se...
