Abstract
A system and method enabling a recipient correspondent of a keyed PV signature to convert it to a signature with properties similar to a traditional signature (i.e., where the message is public and may be verified by anyone), removing the keyed aspect of the signature. The recipient correspondent may transfer the converted signature to a third party and provide the third party with a proof of knowledge such that the third party may be convinced that the originator of the signature signed the message.
