Cryptographic identification of false base stations

A computer system comprising:

• one or more processors, and
• one or more computer storage media storing computer-useable instructions that, when used by the one or more processors, cause the one or more processors to:
• receive, by a false base station identification system, a base station certification request from a user computing device, wherein the base station certification request comprises at least a base station identifier, and a base station signature encrypted utilizing an encryption key;
• utilizing, by the false base station identification system, a decryption key associated with the false base station identification system, decrypt the base station signature;
• based on decrypting the base station signature, determine, by the false base station identification system, that a base station associated with the base station identifier is a false base station;
• and
• store, by the false base station identification system, the base station identifier, in association with a false base station indicator in a data store.

One or more non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed by a computing device, perform a method comprising:

• transmitting, by the computing device, a request for a verification message to a base station;
• receiving, by the computing device, an encrypted verification message from the base station, the encrypted verification message comprising at least a base station identifier and a signature encrypted using an encryption key associated with the base station;
• decrypting, by the computing device, the signature utilizing a decryption key associated with the computing device;
• based on decrypting the signature, determining, by the computing device, that the encryption key does correspond to the decryption key;
• and
• based on determining that the encryption key corresponds to the decryption key, storing, by the computing device, the base station in a data store, wherein the base station identifier is stored in association with a real base station indicator.
