A system and method for access control is provided. In one embodiment, a system includes a computing device connected to an access server that controls the ability of the computing device to access to a computing resource, such as the Internet. The access server connects to an activation server via a network. The activation server is operable to receive a request for to generate a certificate for the computing device from the activation server. The activation server is operable to generate the certificate and embed a unique identifier of the computing device and/or the access server and/or the like inside the certificate. Once generated, the certificate is installed in the computing device. When the computing device initiates a request to access the computing resource, the computing device initially sends the certificate to the access server. If the certificate received by the access server does not include the expected unique identifier(s), then access to the computing resource is prevented and/or restricted. If the key received by the access server includes the expected unique identifier(s), then access to the computing resource is permitted. |
