Proxy blind signature is a cryptographic research hotspot, and has been applied in many occasions. Many proxy blind signature schemes were proposed, however, all the schemes rely on secure channels to transmit proxy secret key. Therefore, Lu, Cao and Zhou proposed a new proxy blind multi-signature scheme recently, which does not need a secure channel and is provably secure under the random oracle...
In a designated verifier proxy signature scheme, one can delegate his or her signing capability to another user in such a way that the latter can sign messages on behalf of the former, but the validity of the resulting signatures can only be verified by the designated verifier. Several designated verifier proxy signature schemes have been proposed so far. However, most of the schemes were proven secure...
