Abstract
Embodiments of this application provide a method and an apparatus for detecting a false base station. The method includes: A network device sends system information to a terminal device, where the system information includes a first signature of the system information and a first timestamp, and the first timestamp identifies time at which the network device generates the first signature. The network device receives private information from the terminal device. The network device signs the private information of the terminal device by using a private key corresponding to the network device, to obtain a second signature. The network sends the second signature to the terminal device. According to the foregoing method, the terminal device can accurately verify whether the terminal device is attacked by a false base station, to improve communication security.
