Chameleon signatures were introduced by Krawczyk and Rabin, being non-interactive signature schemes that provide non-transferability. However, that first construction employs a c...

Abstract. Chameleon signatures simultaneously provide the properties of nonrepudiation and non-transferability for the signed message. However, the initial constructions of chamele...
