&gt; If I&#x27;m reading this right then they basically have access to all 3G&#x2F;4G data and they do so in a way that cannot be detected.<p>How did you reach that conclusion? While probably true, this article merely (poorly) describes how GCHQ &quot;improved&quot; on another backdoored encryption standard by making snooping impossible to detect.<p>This is only a thing because GCHQ has started certifying software and supporting the MIKEY-SAKKE protocol is a hard requirement.
