TrustZone Architecture: Hardware-Level Privacy Protection for Smartphones

TrustZone implements a hardware‑level privacy shield for smartphones by partitioning CPU, bus, memory, peripherals and interrupts into a Secure World and a Normal World, using ARMv8 exception levels and extensions such as SCR, TZPC, TZASC, GIC and MMU to isolate user data from non‑secure software.

Android Kernel Hooking: Bypassing GKI Limits & Memory Protection

This article examines the security challenges of Android and IoT devices built on ARM/ARM64 platforms, explains how Google's Generic Kernel Image (GKI) restricts kernel modifications, and provides detailed techniques—including memory‑page attribute manipulation, remap_pfn_range, and assembly‑level hook implementations—to safely inject custom functionality into the kernel while addressing write‑protection, concurrency, and module‑unloading issues.
