This paper aimed at the popular cloud computing technology, analyzed the security problems it faced. A model for protecting the data's integrity and confidentiality in the cloud server was raised, which took the reference of BLP (Bell-LaPadula) model, and the CW (Clark-Wilson) model, and component, security axiom and realization of the model are given. Cloud computing is an emerging computing model, which is based on grid computing, it is a distributed computing.
