What is Efficient Structure-Preserving Signatures about?

The document presents efficient structure-preserving signature schemes for large messages consisting of multiple group elements, achieving optimal verification key and signature sizes. It introduces both randomizable and strongly existentially unforgeable signatures, with a focus on fully structure-preserving signatures where the secret signing key consists solely of group elements. The proposed schemes demonstrate significant improvements in efficiency compared to existing methods, allowing for flexible si
