Electronic funds transfer protocol using domain-verifiable signcryption scheme

Abstract

In this paper, we propose Domain-verifiable signcryption scheme, which is applied to the Electronic Funds Transfer(EFT) protocol, that only predetermined n participants within the domain of protocol participants can decrypt their own part of message and verify whole transaction. The computational cost of our scheme is as low as that of Zheng’s scheme assuming that Trusted Third Party(TTP) must be used to keep partial information for participants confidential and multi-verification. Our scheme does not require the role of TTP.
