Moreover a multisigning operation may be required to be performed simultaneously (in some sense) by all the involved cosigning parties. We describe a complete cooperation-based signature scheme achieving such requirements. It is based on mental games and in particular on the Guillou-Quisquater zero-knowledge scheme. In our scheme, the cosigners interact with an intermediate entity, the combiner, to produce a multisignature. Only one interactive exchange is required. The scheme is practical and secure. A cheating combiner can only prevent the operation from happening but it will be immediately detected. No impersonation, substitution, or coalition attacks are possible.
