A method includes receiving authentication information for a client device at a server. The authentication information includes a network address of the client device, a geographic location of the client device, and a first result of a one-way hash function based on a combination of the network address, an authentication seed, and a first secret. The method includes computing, with the server, a second result of the one-way hash function based on a combination of the network address, the authentication seed, and a second secret. The method also includes enabling the client device to access a second network in response to a determination by the server that the first result matches the second result and a determination by the server that the client device is authorized to access the second network based on the geographic location. |
