摘要
商务交易信息在Internet上传输,如何保证其传输数据不被黑客窃取且篡改,并保证实现数据的安全传输及交易对方的身份认证技术是电子商务能否得到发展的关键。针对电子商务中的安全性问题,文章采用最新的高级加密标准(AES)的Rijndael算法和目前国际上广泛应用的非对称密码(RSA)算法相结合,提出了一种新的混合数据加密与数字签名方法。该方法综合发挥了对称密钥密码体制的高速简便性和不对称密钥密码机制密钥管理的方便性和安全性,实现了电子商务中数据加密传输、数据完整性校验、数字签名等功能。这样在客户、商家和支付网关之间建立了一个安全的网络通道,保证了电子商务系统的安全应用。
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 e -commerce, the paper adopts new Rijndaelalgorithm that belongs to the criteria of Advances Encryption and asymmetrical cipher （RSA） usedextensively 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.
