How to Obtain Fully Structure-Preserving (Automorphic) Signatures from Structure-Preserving Ones
signature trapdoor signature fully structure-preserving
2016/12/9
In this paper, we bridge the gap between structure-preserving signatures (SPSs) and fully structure-preserving signatures (FSPSs). In SPSs, all the messages, signatures, and verification keys consist ...
Efficient Fully Structure-Preserving Signatures for Large Messages
Digital signatures pairing-based cryptography full structure-preservation
2015/12/23
We construct both randomizable and strongly existentially
unforgeable structure-preserving signatures for messages consisting of
many group elements. To sign a message consisting of N = mn group ele...
