Secure Boot

As you can see, the boot chain has evolved significantly. In 2015, the possible attack area was condensed, and the Secondary Bootloader (SBL) chain was merged into one unified SBL. As we move further down the line, we see SBL entirely replaced with Qualcomm’s new proprietary solution, the eXtensible Bootloader (XBL), which mitigated many of the security issues SBL presented. Aboot has also matured from LittleKernel (an open-source bootloader) with some additions into a fully independent solution now called the proprietary Android Bootloader (ABL). This new bootloader allows the use of UEFI, among many other security and quality-of-life enhancements, for developers/OEMs. The system_as_root configuration has also improved security, as well as the general architecture, significantly. It moves the Android-ramdisk from being stored in the boot image to being stored in the system partition, which, as the name would imply, is mounted as ’/’. This was done in part to allow it to be verified by dm-verity/Android Verified Boot. NOTE: The new seamless update system coined “A/B” is separate from system_as_root, even though they are commonly seen hand in hand. OEM’s have the option of implementing one and not the other.
