A system comprises: a first communications device(120) requesting playback of contents; a DRM device(140) decoding encoded contents corresponding to the requested contents and transmitting the contents encoding the contents again with a preset session key to the first communication device; and a second communication device(130) transmitting data between the first communication device and the DRM device by connecting to the DRM device. The DRM device performs cross certification with the first communication device when session setting is requested. The DRM device generates the preset session key when the cross certification with the first communication device is successful.

Abstract: A device and a method for detecting an intrusion code are provided to generate a customized immune database capable of determining the intrusion code, prevent damage caused by new or mutated malicious codes with the customized immune database, and obtain a diagnostic for the new or mutated malicious codes from a system having immunity to the new or mutated malicious codes. A setting value input unit(110) receives setting values customized to each group. An immune database generator(120) generates an immune database(140) based on the setting values. An intrusion code determiner(130) determines whether input data is an intrusion code based on the immune database. The setting value input unit receives a group feature key, a resident code list, and a random pool generation factor. The immune database generator includes a feature extractor extracting features of resident codes by using the group feature key, a pool feature generator generating random pool features based on the group feature key and the random pool generation factor, a similarity calculator calculating similarity between the features of the resident codes and the random pools, and an immune database generation manager generating the immune database from the features having the similarity under a threshold.

Abstract: A method for protecting a broadcast frame, a terminal for authenticating the broadcast frame and an AP(Access Point) for broadcasting the broadcast frame are provided to check effectiveness of a key via a symmetric encryption scheme and to authenticate a BMF(Broadcast Management Frame) as soon as the BMF is received. A method for protecting a broadcast frame comprises the following two steps. An AP broadcasts a beacon and an MBF(Maintenance Beacon Frame) to plural terminals for an MBWP(Maintenance Beacon Waiting Period). The AP broadcasts at least BMF during a BMFWP(Broadcast Maintenance Beacon Waiting Period). The step S310 can be divided into two following sub-steps. The AP generates the MBF including a previous key for a previous beacon cycle, a beacon message integrity code, a BMF number transmitted to a current beacon cycle and a message integrity code(S311) and broadcasts the MBF to the plural terminals(S312).

Abstract: A method for assigning conditional access system (CAS) keys to a terminal to thus reduce the number of entitlement management messages (EMMs) required to send contents to a digital broadcast subscriber. To this end, a broadcast center causes transmission of the CAS-related key to limit access to the digital content, over a mobile communication network used for a mobile communication, and causes transmission of the digital content over a digital broadcasting network used for digital broadcasts. Since the CAS-related key is transmitted to the digital broadcast subscriber's terminal over the mobile communication network, it is possible to effectively utilize the frequency bandwidth of the digital broadcasting network for the digital broadcasting. Furthermore, the security of the CAS-related key can be strengthened by sending the CAS-related key to the terminal over the mobile communication network.
