There's no "mobile Linux". Linux supports Secure Boot just fine, and if a distro wants to sandbox applications that too is done by just configuring Linux to do so (after all, that's what Android does).

    Why? That has nothing to do with the topic we're discussing. You can configure Linux as Android does it, or choose not to.

    (Secure Boot is what enables "Verified boot" - which is just Android's name for a common sense secure boot loader implementation which is the norm in well protected IoT systems etc)

    Android boots in layers that are encrypted with different keys. The first key in the TPM enlocks the base OS up to the lock screen. From there a pin is entered and the rest of the system is decrypted.

    If a compromise happened in the OS the phone would just fail to boot since the integrity of the system is validated by the TPM.

    Yes, that's how a normal bootchain works in every system ever - like the IoT device running Linux I'm right now working with.

    Linux does not suck on phones regarding security. Linux is what brings the security mechanisms faulty ascribed to as being "Android's". See previous posters claiming it was all "extensive modifications" by Android and not just Linux security mechanisms.

    Feel free to get a Fairphone 4, sign your Ubuntu Touch image with keys supported by the chipset and off you go. The fact that no one is selling you that has no relevance whatsoever to whether "Linux" supports it.

    Linux doesn't have the same permission controls. SElinux profiles would need to be manually configured for each app which would take a lot of time.

    Mobile linux also doesn't support measured boot which is what is used to protect the system in the case of theft. Before I consider mobile Linux it would be nice if there was a detailed security review of the entire system.

    I think this will sort itself out quicker if you show me what "mobile linux" is.
