Abstract
A mobile device is provided which includes a working memory having a memory area divided into a secure domain and a non-secure domain; and a system-on-chip configured to access and process contents stored in the secure domain. The system-on-chip includes a processing unit driven by at least one of a secure operating system and a non-secure operating system; at least one hardware block configured to access the contents according to control of the processing unit comprising a master port and a slave port which are set to have different security attributes; at least one memory management unit configured to control access of the at least one hardware block to the working memory; and an access control unit configured to set security attributes of the slave port and the master port or an access authority on each of the secure domain and the non-secure domain of the working memory.
