Secure authentication of remote equipment

A network device comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the network device to:
• receive, from a first computing system, a challenge message;
• send, to the first computing system, a response to the challenge message;
• and
• receive, from the first computing system and based on the response, an indication of permission to transmit non-secure data between a user device and a second computing system.

A non-transitory computer-readable storage medium storing instructions that, when executed, cause:

• receiving, by a network device and from a first computing system, a challenge message;
• sending, by the network device and to the first computing system, a response to the challenge message;
• and
• receiving, by the network device from the first computing system and based on the response, an indication of permission to transmit non-secure data between a user device and a second computing system.
