Authentication extension to untrusted devices on an untrusted network

An authentication server for providing premium communication services via an untrusted network, comprising:

• a processor;
• a non-transitory memory;
• and
• an application stored in the non-transitory memory that, when executed by the processor, configures the processor to:
• receive a request from an untrusted communication device to access a premium communication service via the untrusted network, wherein the request comprises an internet protocol (IP) address of a router;
• and
• authenticate the untrusted communication device for a time period based on a time-to live value included in an earlier authentication for a trusted mobile communication device, the authenticating comprising:
• match the IP address of the router from the request with a previously stored source IP address of the router associated with a message received earlier from the trusted mobile communication device, wherein the trusted mobile communication device is authorized to access the premium communication service via the untrusted network;
• upon matching the IP address of the router from the request with the previously stored source IP address of the router associated with the message sent by the trusted mobile communication device, obtain a mobile directory number of the trusted mobile communication device;
• send a message to the mobile directory number of the trusted mobile communication device via a cellular wireless communication link, wherein the message requests a confirmation from the trusted mobile communication device before proceeding with authentication of the untrusted communication device in accessing the premium communication service;
• in response to the confirmation, determine whether the request is received within the time period indicated by the time-to-live value included in the earlier authentication for the trusted mobile communication device;
• upon determining that the request is received within the indicated time period, generate a cookie associated with the untrusted communication device;
• embed a new time-to-live value associated with premium content access within the cookie, wherein the new time-to-live value indicates a window of time for which extended authentication of the untrusted communication device is valid;
• and
• send the cookie to the untrusted communication device via the untrusted network, wherein the untrusted communication device and the trusted mobile communication device are different devices.
