    • The present invention relates to a malicious traffic isolation system and method using botnet information, and more particularly, to a malicious traffic isolation system and method using botnet information, in which traffics for a set of clients having the same destination are routed to the isolation system based on a destination IP/Port, and botnet traffics are isolated using botnet information based on similarity among groups of the routed and flowed in traffics. The present invention may provide a malicious traffic isolation method using botnet information, which can accommodate traffics received from a PC or a C&C server infected with a bot into a quarantine area, isolate traffics generated by normal users from traffics transmitted from malicious bots, and block the malicious traffics. In addition, the present invention may provide a malicious traffic isolation method using botnet information, which can provide a function of mitigating DDoS attacks of a botnet.
    • 本发明涉及使用僵尸网络信息的恶意流量隔离系统和方法,更具体地,涉及使用僵尸网络信息的恶意流量隔离系统和方法,其中具有相同目的地的一组客户端的流量被路由到隔离系统 基于目的地IP /端口,并且使用基于路由和流量在业务中的组之间的相似性的僵尸网络信息来分离僵尸网络流量。 本发明可以提供一种使用僵尸网络信息的恶意流量隔离方法,其可以将从被感染机器人的PC或C&C服务器接收到的流量容纳到隔离区域,从而将普通用户生成的流量与恶意机器人传输的流量隔离,并阻止 恶意的流量。 另外,本发明可以提供使用僵尸网络信息的恶意流量隔离方法,其可以提供减轻僵尸网络的DDoS攻击的功能。

    • Provided is an apparatus and method for converting a 10.2 channel signal into a multi-channel signal having a relatively few number of channels, thereby encoding and decoding the 10.2 channel signal. An apparatus for encoding/decoding a multi-channel signal may include a multi-channel signal converter to convert a first multi-channel signal into a second multi-channel signal having a fewer number of channels when compared to the first multi-channel signal, a remaining signal generator to generate a remaining signal using a difference between the first multi-channel signal and the second multi-channel signal, and an encoder to encode the second multi-channel signal and the remaining signal.
    • 提供了一种用于将10.2声道信号转换为具有相对少数声道数的多声道信号的装置和方法,从而对10.2声道信号进行编码和解码。 用于对多声道信号进行编码/解码的装置可以包括多声道信号转换器,用于当与第一多声道信号相比时将第一多声道信号转换为具有较少数量信道的第二多声道信号, 使用第一多声道信号和第二多声道信号之间的差产生剩余信号的剩余信号发生器,以及对第二多声道信号和剩余信号进行编码的编码器。
