Abstract
Methods and apparatus for providing access to a service are disclosed. An example apparatus includes at least one processor, and memory including machine readable instructions that, when executed, cause the at least one processor to perform operations including, in response to receipt of a first network communication, retrieve a first list identifying multicast group memberships of a device existing at a first time, the first list retrieved from a storage device based on an identifier in the first network communication, the first network communication including a second list identifying multicast group memberships of the device existing at a second time later than the first time. The device is authenticated based on a comparison of the first list to the second list. A second network communication is transmitted indicating the device has been authenticated in response to the authentication.
