With the development of computer technology, especially the rapid development of the network, information security is becoming more and more important. In practical applications, access control is the system security technology implement of security policy. It manages all the access request of resource according to the security policy and determines the access request of resource authorities whether or not. And it can effectively prevent illegal users access system resources and legitimate users illegally use of resources. This paper combined the requirements of access control model in scientific data sharing platform. By comparing several major models currently, we summed up their advantages and disadvantages. Finally, according to the characteristics of scientific data sharing platform, we are combining MAC model with ERBAC model and expecting to apply to this platform.
