description Methods and systems for detecting false base stations are provided. A computing device transmits a request for a verification message to a base station. An encrypted verification message comprising a base station identifier and a signature encrypted using an encryption key associated with the base station is received by the computing device. The computing device decrypts the signature included in the encrypted verification message utilizing a decryption key associated with the computer system. Based on the decrypted signature, the computing device determines that the encryption key does not correspond to the decryption key. Based on determining that the encryption key does not correspond to the decryption key, the computing device stores the base station identifier in a data store in association with a false base station indicator.
