Verifiably encrypted signatures (VES) are signatures encrypted
by a public key of a trusted third party and we can verify their validity
without decryption. This paper proposes a new VES scheme whic...

An aggregate signature scheme is a digital signature that supports aggregation: Given n signatures on n distinct messages from n distinct users, it is possible to aggregate all these signatures into a...

Aggregate signatures provide bandwidth-saving aggregation of ordinary signatures. We present the first unrestricted instantiation in the standard model, Moreover, our construction yields a multisignat...

In a verifiably encrypted signature scheme, signers encrypt their signature
under the public key of a trusted third party and prove that they did so correctly. The
security properties are unforgeabi...
