ELECTRONIC APPARATUS AND CONTROL METHOD THEREOF
First Claim
1. An electronic apparatus comprising:
- a memory comprising a protection area and configured to store data of a first operating system (OS) and at least one first program involved with first OS in the protection area;
at least one processor configured to execute the at least one first program and at least one second program involved with a second OS having an authority higher than the first OS; and
a memory monitor comprising circuitry configured to;
to detect whether an access to the protection area of the memory occurs;
to interrupt the access if the access occurs; and
to perform a security verification of the data stored in the protection area.

Abstract
An electronic apparatus and a control method thereof are provided. The electronic apparatus includes a memory having a protection area and storing data of a first operating system (OS) and at least one first program involved with first OS in the protection area; at least one processor configured to execute the at least one first program and at least one second program involved with a second OS having an authority higher than the first OS; and a memory monitor comprising circuitry configured to detect whether an access to the protection area of the memory occurs, to interrupt the access if the access occurs, and to perform a security verification of the data stored in the protection area. The electronic apparatus may guarantee and/or improve integrity thereof using a hardware device, which can directly monitor the memory at a CPU environment in which a security area and a general area are separated.
