This research based on Secure Electronic Transaction (shorten as SET) protocol, is purposed to an anonymous and security B2C E-Invoice system (SET-B2CEIS, Secure Electronic Transaction-B2C E-Invoice System). This system is established on the technique of Symmetric Encryption, Hash function, Triple Signature, Digital Envelope, Bit Commitment. We develop a SET-B2CEIS protocol which can keep the privacy of buyer and the confidentially, integrity, authentication and, nonrepudiation of transaction in our protocol have three characteristics (1) Once the buyer decides to devote E-Invoice, the right of E-Invoice can be transferred safely to the receiver. The buyer can not regret devoting and do not have the right to convert the premium of uniform invoice. (2)The Ministry of Finance can check whether the merchant correctly send it the E-Invoice, which can avoid tax evasion; (3)Buyer can directly convert the premium of uniform invoice anonymously .The merchant can not convert the premium of uniform invoice actively to avoid converting incorrectly and avoid not sending the invoice paper to buyer. Besides, the Ministry of Finance can test and verify the correction of receiver, to prevent the premium miss-payed. In this paper we describe how this E-Invoice system can satisfy our goal in safety and function by qualitative analysis method, and we will compare our system with the practicing paper invoice system based on SSL protocol and practicing E-Invoice system.
