Zanny, I disagree with your use of the &quot;nothing is completely secure&quot; truism as an argument against &quot;storing private keys inside cellphones is not a good idea&quot;.<p>The local police department has ISMI catchers.<p>I estimate they won&#x27;t have the ability to extract a file via the baseband until something like eZing becomes ubiquitous.<p>At that point, automated private key extraction will just become another feature of the ISMI catchers.<p>All of this is tangential to the real problem: basebands.  Both in cell phones and cable modems.  Time to take &#x27;em back.  You wouldn&#x27;t allow OTA updates of your router or PC...  Now would you?<p>I&#x27;ll anticipate one response: &quot;But, giving consumers control of their PHYs would be hell for the cellular&#x2F;cable operators!&quot;  Well, after a few years, their&#x2F;our networks (and devices) will be more secure.
