US 2022/0038904 A1 · WIRELESS-NETWORK ATTACK DETECTION

Abstract

In some examples, a terminal can establish wireless communication with a base station. The terminal can determine a challenge, transmit the challenge, receive a response, and determine that the response is valid. The terminal can, in response, establish a secure network tunnel to a network node. In some examples, a terminal can determine a first communication parameter associated with communication with the base station. The terminal can receive data indicating a second communication parameter via a secure network tunnel. The terminal can determine that the communication parameters do not match, and, in response, provide an indication that an attack is under way against the network terminal. Some example terminals transmit a challenge, determine a response status associated with the challenge, and determine that an attack is under way based on the response status.

Dependent claims

A network terminal, comprising:

a secure storage unit having stored therein a stored key;
and
a control unit configured to perform operations comprising:
attaching to a wireless network using stored network credentials;
determining a challenge;
after attaching to the wireless network, transmitting the challenge to a network node via the wireless network;
subsequently, determining a response status associated with the challenge;
determining that an attack is under way based at least in part on the response status;
providing an indication that the attack is under way in response to the determining that the attack is under way;
and
wherein at least:
the determining the challenge is based at least in part on the stored key;
or
the determining that the attack is under way is based at least in part on the stored key.
