摘要：A system and method for access control is provided. In one embodiment, asystem includes a computing device connected to an access server that controls theability 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 fromthe activation server. The activation server is operable to generate the certificate andembed a unique identifier of the computing device and/or the access server and/or thelike inside the certificate. Once generated, the certificate is installed in the computingdevice. 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 certificatereceived by the access server does not include the expected unique identifier(s), thenaccess to the computing resource is prevented and/or restricted. If the key received bythe access server includes the expected unique identifier(s), then access to the computingresource is permitted.
