Improving the Security of Cloud Computing using Trusted Computing Technology

Cloud Computing is a collection of computers and servers that are publicly accessible via Internet. It is a significantly new idea that influence the power of internet to process, store and share data from a network of remote servers located anywhere in the world. That is a good way to share a many kinds of distributed resources, but it also makes security problems more complicate and more important for users than before. This paper analyses some security services in cloud computing environment and a method to build a trusted computing environment for cloud computing system by integrating the trusted computing platform into cloud computing system. Trusted Computing Platform (TCP) model can improve the cloud computing security and will not bring much complexity to users. In this model, some important security services including encryption, authentication, integrity and confidentiality are provided in cloud computing system.
