- Additional information
- The research was supported by a major grant from the Office of Naval Research. We show the first delegations of entire cryptographic schemes: the well-known digital signature schemes by El-Gamal, Schnorr, Okamoto, over the q-order subgroup and their variants based on elliptic curves. Previous efficient delegation results were limited to the delegation of single algorithms within cryptographic schemes.
