Consider a network of processors among which elements in a finite field K can be verifiably shared in a constant number of rounds. Assume furthermore constant-round protocols ar...
Privacy-preserving protocols allow multiple parties with private inputs to perform joint computation while preserving the privacy of their respective inputs. An important cryptogr...
Multisignatures allow n signers to produce a short joint signature on a single message. Multisignatures were achieved in the plain model with a non-interactive protocol in groups ...
