A method to ensure data security in e-business cloud

Since the concept “cloud computing” was first put forward, arguments about its data security have been lasting, which involve two aspects. One is how to keep the information of client from hackers, the other is the assurance of security and accuracy when passing data to users. This paper shall explore in depth the solutions to security issues especially happening to the skyrocketing e-commerce established on cloud computing technology. By using key cryptographic system (KCS), data security of e-business cloud will be well-assured. Practical ways to realize the KCS method are discussed in this paper.
