As a result of the network, exchange has already been applied to our daily life and then people can transact business on the network. Fair exchange requires that both parties can all ob-tain expected item in reciprocity case. For instance, after a customer (C) made the pay-ment then he will receive the merchandise. In the same way, a merchant (M) sent the merchandise to the customer should get the payment. With the transmission of messages, both parties can verify the encrypted product, product decryption key, and payment, and reach the principle of fair exchange. Though the network exchange has already been popularized day by day, while any malicious outsider that has some special equipment or software can intercept the information in the network, or imitate others to convey wrong information. Hence anonymity ensures that the identity of two parties is not revealed during the exchange process.
In this thesis, we propose a new anonymous fair exchange protocol. A trusted third party (TTP) will act as the intermediary between the two parties. This protocol has fol-lowing features: (1) guaranteeing the fair exchange in transaction, (2) assuring anonymity for both parties during the transaction, (3) ensuring that both parties all can prove the correctness of the receiving message, (4) message exchange is efficient.
