Abstract:
PURPOSE: An authentication method of a client which has a limited resource, a storage medium capable of being read by a machine, a client and server are provided to be safe from a man-in-the-middle attack and prove a safety based on a mathematical conundrum. CONSTITUTION: A client(100) and a server(200) respectively include first and second memories(110,210), first and second communication units(120,220), and first and second control units(130,230). The first and second memories store data like a private key which is necessary for a preset authentication process. The first communication unit(120) performs a wireless communication with the server. The second communication unit(220) performs a wireless communication with the client. The first control unit(130) performs a preset authentication process about the server by using the first memory or the first communication unit. The second control unit(230) performs a preset authentication process about the client by using the second memory or the second communication unit.

Abstract:
PURPOSE: A method for authenticating a storage device, a host device and a record medium are provided to prevent a suitable holder of contents from not consuming possessed contents because of apparatus certification failure. CONSTITUTION: A storage device(100) includes a second interface unit(110), a second certification unit(120), a memory(130) and a second control unit(160). The second interface unit modulates data inputted from the second certification unit and the second control unit into a wire or wireless signal, and then transmits the signal to a host device(200) and demodulates the signal to output. The second certification unit authenticates the host device on the basis of the discarding of a second certificate. The memory stores CRL, contents and additional information files. The second control unit is reported of certification success from the second authentication unit, and transmits the contents to the host device when the certification is successful.

Abstract:
PURPOSE: An authentication method of a non-volatile memory device and a device thereof are provided to allow a host device to perform authentication based on authentication information obtained from the non-volatile memory device, thereby not using an error check/correction means. CONSTITUTION: An interface unit communicates with a non-volatile memory device(220). An authentication verifying module(110) transmits challenge information to the non-volatile memory device through the interface unit. The authentication verifying module receives authentication information for the challenge information. The authentication verifying module performs the authentication of the non-volatile memory device by using the authentication information. The authentication information is generated by using the challenge information and private key information stored in the non-volatile memory device.

Abstract:
PURPOSE: A DRM solution managing method and an apparatus thereof are provided to install a DRM solution in a user device even through a DRM solution is not installed in the user device in an IPTV environment. CONSTITUTION: In case a DRM(Digital Rights Management) solution is not installed in a user device, a DRM management server transmits a DRM installing request message to the user device(611). The user device and a DRM download server perform a process for downloading and installing a DRM module(613). The user device transmits a domain registration request message to the DRM management server(617). The user device and the DRM management server perform a registration process(619).

Abstract:
PURPOSE: A DRM(Digital Right Management) function managing method and a device thereof are provided to install a DRM function in a user device even if the DRM function is fundamentally not installed in the user device. CONSTITUTION: A transceiving unit(230) transceives various messages and data. When a purchase record about DRM contents of a user device is reported, a DRM managing unit confirms a content access right corresponding to the DRM contents and DRM information stored in a DRM information storage unit(220). The DRM information corresponds to the user device. If a DRM module installed in the user device is not capable of executing the content access right, the DRM managing unit determines a first DRM module installing a corresponding DRM function.

Abstract:
PURPOSE: A DRM module download method and an apparatus thereof are provided to enable a client terminal to use DRM content by defining a file format in order to include DRM module download information in a used file when supplying DRM content. CONSTITUTION: A controller(110) receives a content file including DRM content and obtains DRM download information corresponding to a DRM system. The controller transfers address information for indicating a location of a DRM module and identification information of the DRM system to a download agent(170). The download agent generates a DRM module request message by using address information of the DRM system and transmits the DRM module request message to a DRM download server.
