Commercial information is transmitted on Internet.How to guarantee the transmission of the data which is not eavesdropped and revised by the hacker on the net,how to realize the security of transmitting the data,and identity for both trade confirms,which is the key to development of the e-commerce vigorously.Directly against the security question in ecommerce,the paper adopts new Rijndael algorithm that belongs to the criteria of Advances Encryption and asymmetrical cipher(RSA) used extensively in the world at present.By combining them,the article had put forward a kind of new mix data encrypting and digital signature scheme.The scheme developed symmetrical key cipher that has high speed and runs conveniently and asymmetric key cipher mechanism that is convenient and security.The paper realized the function of mix data encryption transmission,data integrality examination,digital signature and so on.So we set up a safe network channel among the customer,the trade company,and the gate of paying the net in this way.In the channel,we can guarantee the secure application of e-commerce.
