Blind signatures enable a receiver to obtain signatures on messages of its choice without revealing any message to the signer. Round-optimal blind signatures are designed as a two-round interactive protocol between a signer and receiver. Coincidentally, the choice of message is not important in many applications, and is routinely set as a random (unstructured) message by a receiver.
With the goal of designing more efficient …
