Lattices zero-knowledge proofs group encryption anonymity
2016/12/9
Group encryption (GE) is the natural encryption analogue of group signatures in that it allows verifiably encrypting messages for some anonymous member of a group while providing evidence that the rec...
We present group encryption, a new cryptographic primitive which is the encryption analogue
