A Domain Transformation for Structure-Preserving Signatures on Group Elements
We present a generic transformation that allows us to use a large class of pairing-based signatures to construct schemes for signing group elements in a structure preserving way. A...

Optimal Structure-Preserving Signatures in Asymmetric Bilinear Groups
Structure-preserving signatures are signatures defined over bilinear groups that rely on generic group operations. In particular, the messages and signatures consist of group elem...

Short Signatures from the Weil Pairing
Abstract. We introduce a short signature scheme based on the Computational Diffie-Hellman assumption on certain elliptic and hyper-elliptic curves. The signature length is half the...

A New and Efficient Signature on Commitment Values
We present a new short signature scheme based on a variant of the Boneh-Boyen's short signatures schemes. Our short signature scheme is secure without requiring the random or...
