An Efficient Threshold Access-Structure for RLWE-Based Multiparty Homomorphic Encryption

Jean-Pierre Hubaux, Christian Vincent Mouchet

We propose and implement a multiparty homomorphic encryption (MHE) scheme with a t-out-of -N-threshold access-structure that is efficient and does not require a trusted dealer in the common random string model. We construct this scheme from the ring-learni ...
