1. A method for detecting an unauthorized access point, comprising:
receiving, from an access point, network information allocated to a terminal device by the access point regarding a wireless network access by the terminal device via the access point;
making, by the terminal device, a wireless transmission to the access point, the wireless transmission including a message directed to a validation server, the message comprising the network information and requesting a validity verification of the network information;
determining, by the terminal device, that the access point is unauthorized when at least one from among a response indicating that the network information is invalid is received from the validation server, or the validation server is inaccessible to the terminal device for a predetermined time following the wireless transmission,
wherein, in response to determining that the access point is unauthorized, the terminal device discontinues wireless communication between the terminal device and the access point, and
wherein, in response to a receiving a response indicating that the network information is authorized from the validation server, the terminal device continues the wireless communication between the terminal device and the access point.
