电子商务安全与数据加密技术研究 摘要：Abstract E-commerce is the utilization of computers, mobile communications and Internet platform for commercial activities. Is a kind of way through the Internet for all kinds of business transactions, combined with modern logistics, communications and many other aspects of the technical support, realize the height of the trading information, so as to provide a very comprehensive, complete information trading platform, make more network, electronic business activities.Compared to traditional business, it has the more obvious advantages, it can provide a very powerful product information, greatly simplifying the purchasing process, and also save a lot of transaction costs, so in recent years, its development speed is very fast. However, due to its development time is not long enough, so there are many problems in terms of transaction security can not provide protection ancestor, therefore, along with research data encryption technology to flourish, as a major electricity supplier activities carried out security technology, it is also the electricity supplier of many security technologies an integral part. Covering e-commerce data encryption technology mainly rely on the Internet to complete, to achieve data encryption of information transmitted over the network. This article focuses on two aspects of the electricity industry and the providers of data encryption and associated with each other, and from the theory and research results, discuss the depth of knowledge of all aspects of it.
