Protection against reverse engineering in ARM

With the advent of the mobile industry, we face new security challenges. ARM architecture is deployed in most mobile phones, homeland security, IoT, autonomous cars and other industries, providing a hypervisor API (via virtualization extension technology). To research the applicability of this virtualization technology for security in this platform is an interesting endeavor. The hypervisor API is an addition available for some ARMv7-a and is available with any ARMv8-a processor. Some ARM platforms also offer TrustZone, which is a separate exception level designed for trusted computing. However, TrustZone may not be available to engineers as some vendors lock it. We present a method of appl…
