Abstract
A method and apparatus for protecting the integrity of a mobile terminal are provided. The mobile terminal includes a secure world for preventing unauthorized access to resources, and a normal world other than the secure world. The integrity protection method for the mobile terminal includes sensing a power-on of the mobile terminal, verifying, by a trusted entity in the normal world, the integrity of a first subsequent entity, and sending, when an integrity breach is detected in the first subsequent entity, by the trusted entity, a modification indication signal to the secure world.
