In this paper we consider the following natural extension: is there a generic construction of "identity-based signature schemes with additional properties" (such as identity-based blind signatures, verifiably encrypted signatures, ...) from PKI-based signature schemes with the same properties? Our results show that this is possible for great number of properties including proxy signatures; (partially) blind signatures; verifiably encrypted signatures; undeniable signatures; forward-secure signatures; (strongly) key insulated signatures; online/offline signatures; threshold signatures; and (with some limitations) aggregate signatures. Using well-known results for PKI-based schemes, we conclude that such identity-based signature schemes with additional properties can be constructed, enjoying some better properties than specific schemes proposed until know. In particular, our work implies the existence of identity-based signatures with additional properties that are provably secure in the standard model, do not need bilinear pairings, or can be based on general assumptions.
