A Simple Security Model Based on Cloud Reference Model

Cloud computing is Internet-based computing, whereby shared resources, software and information, are provided to computers and devices on-demand. That is a kind of computing paradigm and means service - oriented architecture. but it also makes security problems more complicate and more important for users than before. In this paper, we define cloud and its characteristics firstly, and then propose a security model based on Cloud Computing Model (SM_CRM). Finally, the experimental results show that the SM_CRM has the more stable performance when facing the attack threat.
