Abstract: PURPOSE: A server and a client for processing a security program by using a real-time decryption key distribution method and a control method thereof are provided to produce a security platform based on downloading by adding a function of real-time control through online key distribution. CONSTITUTION: A server(300) transmits a security program. A client(320) is designed to execute a received security program. A security platform(305) of the server analyzes an original security program. A segmentation module(306) partitions codes of the original security program. The segmentation module is designed so that the partitioned code is collected in a block(307). An encryption module(308) encrypts the partitioned code. The encryption module arranges a checking module(330) by changing an execution location of the security program. A packing module(309) packs encrypted data by using a changed header file(304) instead an original header file(303).

Abstract: A method and a device for hierarchically grouping a plurality of channels for supporting condition access are provided to support all business models provided from a CAS(Conditional Access System) while reducing the number of encryption and message transmission of the CAS by grouping the channels effectively. A group manager(110) generates a plurality of groups grouping a plurality of channels, sets up a hierarchical relation among the groups to enable a lower group to be included in upper groups and enable the upper groups to include more than the lower groups, and generates a plurality of packages including the groups having the hierarchical relation. A group key manager(120) assigns a group key to each group, and obtains/outputs the group keys of all groups included in the package when the group key of the package is requested. A data storage unit(130) stores the group keys assigned to each group. The group manager includes a group generator(111), a hierarchical relation checker(113), a cycle checker(114) and a hierarchical relation setting part(112).

Abstract: A device and a method for transceiving digital contents for DRM(Digital Rights Management) are provided to prevent illegal copy or distribution, and enable a user to play the contents without a separate player by encoding/inserting the contents into a one-time player, transmitting the encoded digital contents, and enabling the one-time player to decode/play the encoded contents with encryption information included in the one-time player. An encryption information generator(140) generates the encryption information. A content encoder(120) encodes the contents selected from the user by using the encryption information. A one-time player generator(130) generates the one-time player by inserting the encryption information into the player corresponding to the contents. A one-time content generator(150) generates one-time contents by combining the encoded contents received from the content encoder and the one-time player received from the one-time player generator, and transmits the one-time contents to the user.
