摘要： An apparatus and method for providing a security domain are provided. The apparatus includes a security domain which is not connected to an external system and which manages a digital rights management (DRM) license requiring security; a non-security domain which can be connected to the external system and which manages encrypted DRM content; and a virtual controller which controls the security domain and the non-security domain. The method includes requesting checking of a license for encrypted content; checking whether the license for encrypted content exists, in response to the requesting checking of the license; and if it is determined that the license exists, requesting transmission of encrypted content, decrypting the encrypted content, and playing the decrypted content.

摘要： Provided is a method of restricting use of contents in a virtual system comprising at least one virtual machine implemented by applying virtualization technology to a predetermined device. The method includes: reading a first device identifier from the device in order to identify the device; reading a second device identifier, which is a device identifier allocated to the at least one virtual machine, from the at least one virtual machine; determining whether the first device identifier is identical to the second device identifier; and selectively restricting use of contents in the at least one virtual machine based on a result of the determining.
