초록
In this paper, we present a secure on-line lottery protocol which consists of three entities: the players, the lottery provider and the bank. We utilize blind signature and hash chain technique as basic building blocks. Our protocol faithfully satisfies the general security requirements to deal with electronic transactions in safe. The proposed protocol reduces the number of communications and all transactions are executed through the Internet(On-line). By using bank as a notary and bulletin board managed by the lottery provider, we can easily settle down potential disputes which frequently occur during commercial transactions.
