During operation a security token will indicate whether or not a device is operating in a secured or unsecured state. The security token controls whether or not image validation will take place and if access to security critical resources is allowed. The method and apparatus allow (503) only approved images to be stored and executed on the device, and allow (503) security dependent features to be fully operational when it has been determined (501) that the security token is present. The method and apparatus allow (505) non-approved images to be stored and executed on the device, and not allow (505) security dependent features to be fully operational when it has been determined (501) that the security token is not present.</p> |
