1. A method comprising:
providing, from a base station of a communications provider to a web server, an identifier of a user associated with a user equipment that is communicatively coupled with the base station;
based on the identifier, receiving, by a secure server of the communications provider from the web server, an authentication request;
sending, from the secure server to the user equipment, a command to generate and send a purposely generated malformed packet;
in response to the command, receiving, at the base station from the user equipment, the malformed packet;
performing, by the base station, a checksum associated with the malformed packet that causes a failure of the checksum with a known value;
providing, by the base station to the secure server, a notification of the failure of the checksum with the known value;
authenticating, by the secure server, the user equipment based on the failure caused by the malformed packet that is purposely generated by the user equipment; and
in response to the authentication request and the authenticating of the user equipment, providing, by the secure server to the web server, an authentication response indicating the user equipment has been authenticated, wherein
the authentication response from the secure server causes the web server to send a notification of authorization to access a service of the web server to the user equipment.
