Apple invents tamper prevention for Apple SIM

“Today that USPTO published a patent application from Apple’s senior iOS engineers that focuses on ‘Tamper Prevention for Electronic Subscriber Module (eSIM) Type Parameters,'” Jack Purcher reports for Patently Apple.

“Apple’s invention generally relates to techniques for preventing or at least partially securing Type parameters of electronic Subscriber Identity Modules (eSIMs) stored within an embedded Universal Integrated Circuit Card (eUICC) from being inappropriately modified by mobile network operators (MNOs),” Purcher reports. “The key patent figure that Apple shows as representing this invention best is patent FIG. 5A which illustrates a block diagram of an operating system (OS)-based registry that can be implemented to prevent or at least partially secure Type parameters of eSIMs from being erroneously updated.”

MacDailyNews Take: Highly technical, but another step towards iPhones equipped with Apple SIMs.

  1. Hugely important but largely ignored is the problem with rogue network towers used by many surveillance agencies and illegal organisations abroad. The Guardian had an article a while ago how GCHQ(and presumably the NSA) used these in foreign countries as an easier data collection method rather than hacking the carrier network. If this does anything to mitigate that threat then….yes please. The quicker the better.
