Abstract:
본발명은슬러리전극용개질활성탄의제조방법, 및이를이용하여제조된부피당용량이향상된슬러리전극의제조방법에관한것으로서, 더욱상세하게는활성탄의친수성과유동성을향상시키기위한활성탄의개질방법및 개질된활성탄을이용한슬러리전극의제조방법에관한것이다. 본발명에따라개질된활성탄을슬러리전극으로이용하는경우, 활성탄표면의친수성특성으로인해용매에분산시차지하는부피가적어개질되지않은활성탄에비하여상당히많은양의활성탄이로딩될수 있으며, 다량의활성탄이로딩되었음에도불구하고슬러리전극내에서의유동성을확보할수 있으므로, 슬러리전극의부피당용량을현저하게증가시킬수 있는효과가있다. 따라서, 본발명에따른개질활성탄을이용한슬러리전극은플로우커패시터나플로우축전식탈염장치에유용하게사용될수 있다.
Abstract:
PURPOSE: A system and a method for detecting and tracking an attack of an all-IP network environment are provided to reversely track attach origin site information when a DDoS(Distribute Denial of Service) attack occurs in an all-IP network environment. CONSTITUTION: A manager data unit manages a router. The manager data unit stores and manages various information for reversely tracking attack traffic. A router managing unit manages information of a router managed by a manager system. An attack packet managing unit performs management for reversely tracking attack traffic. A protocol processing unit transceives traffic.
Abstract:
PURPOSE: A SIP protocol service denial attack detection using a hidden markov model, a blocking system and method thereof are provided to instantly block the SIP service denial attack. CONSTITUTION: An attack detection and judgment module(116) receives a probability obtained per each model through a SIP normal modeling unit(124). The attack detection and judgment module presently judges whether the behavior is anomaly or not. The attack detection and judgment module compares the received probability value with a critical value obtained from a normal behavior modeling. If the probability value has a lower figure, the attack detection and judgment module determines the current behavior as an invasion. A user information storing unit(121) stores and manages IP, MA information or e-mail information of a user.
Abstract:
PURPOSE: An attack detecting method using a safe sip protocol and system thereof are provided to supply a protocol which a reinforced authentication and security about a SIP packet. CONSTITUTION: An SIP analysis module(252) checks a session status through an IP former model. If the checked session state is a negotiation state, the SIP analyzed module checks the state through encoding/decoding algorithm(258). The SIP analysis module updates a backlist to a blacklist storing unit or outputs a packet. The encoding/decoding algorithm operates with a SIP formal model unit and the SIP analysis module. The encoding/decoding algorithm encodes or decodes a communication packet corresponding to various password algorithms.
