Abstract: PURPOSE: A method for downloading a restriction receiving device for the digital broadcasting is provided, which blocks the attack inducing the connection of the DCAS host to the site of attacker. CONSTITUTION: A broadcasting service provider certifies a subscriber through a downloadable conditional access system host(120) of the IPTV(Internet Protocol Television) set top box. The DCAS host certifies a personalization server(113) by the exchange of a key in order to download a conditional access system. The personalization server distributes widely the cryptographic key for the encoding of the conditional access client for authentication. The DCAS providing server(112) ciphers the restriction receiving device software by the cryptographic key.

Abstract: PURPOSE: A VoIP(Voice over Internet Protocol) system having a spam call blocking function and a spam blocking method using the same are provided to deal with VoIP spam through the participation of a server and a VoIP user, thereby reducing effectively cost required to block the VoIP spam. CONSTITUTION: A transmitting terminal requests a call connection. In case the number of the transmitting terminal does not exist in an SB-DB(Server Blacklist Database)(123), a CCM(Connection Control Module)(121) transfers a call connect request signal to a receiving terminal. In case the number exists in the SB-DB, the CCM refuses the call connection. An IMM(member Information Management Module)(115) stores member information. An SMM(Server Management Module)(125) stores a transmitting terminal number reported by the receiving terminal or the transmitting terminal number and spam report timing in the SB-DB.
Abstract translation: 目的：提供具有垃圾邮件呼叫阻止功能的VoIP（基于因特网协议的语音）系统和使用其的垃圾邮件阻止方法，以通过服务器和VoIP用户的参与来处理VoIP垃圾邮件，从而有效降低阻塞所需的成本 VoIP垃圾邮件。 构成：发送终端请求呼叫连接。 在SB-DB（服务器黑名单数据库）（123）中不存在发送终端的号码的情况下，CCM（连接控制模块）121将呼叫连接请求信号发送到接收终端。 如果SB-DB中存在该号码，则CCM拒绝呼叫连接。 成员信息管理模块（成员信息管理模块）（115）存储成员信息。 SMM（服务器管理模块）（125）将由接收终端报告的发送终端号码或发送终端号码和垃圾邮件报告定时存储在SB-DB中。
