In this paper, we first propose a non-signature authenticated encryption
scheme, which accomplishes the message authentication, confidentiality, and integrity
for communications on an open channel. Compared with the related works, the proposed
scheme does not require constructing the digital signature so that the computation costs
can be reduced. Based upon the non-signature authenticated encryption scheme, we fur-
ther propose a fair electronic payment system such that the payment information can
be securely transmitted on Internet. Moreover, the proposed electronic payment system
can solve the synchronization problem between the payer and the merchant. Therefore,
the transaction fairness of the payer and the merchant can be efficiently accomplished
in off-line environments. According to the above-mentioned advantages, the proposed
electronic payment system provides an efficient and practical payment tool for electronic
transactions.
