摘要： A string matching device extracts a string by shifting a start position from an input data stream, compares the extracted string with a sub-string included in a target string, and when a prefix of a target string is detected from the string extracted from the input data stream, it selects one of the strings output in the next stage based on the start position of the corresponding string and uses it to detect the sub-string. Also, the device can consecutively detect at least one target string from the input data stream by using a state transition process.

摘要： In a lawful interception system including an interception unit, an application service providing unit, and an Internet access service providing unit, the application service providing unit may receive, from the interception unit, an interception request including interception target information of an interception target. Next, the application service providing unit may transfer a user code corresponding to the received interception target information to the interception unit, and may insert user related information into a packet to be provided to the interception target corresponding to the user code, enabling the packet to be lawfully intercepted. The interception unit may request the Internet access service providing unit for an interception of the packet with respect to the interception target by including the user code.

摘要： A system for electronic monitoring includes a control server and a plurality of monitoring servers. The control server transmits electronic monitoring instructions including identification information on terminals to a plurality of monitoring servers, respectively, based on information of objects to be monitored stored in a database, receives an object confirmation request message including information on suspect object packets from a first monitoring server among the plurality of monitoring servers, and determines whether the monitoring object terminals correspond to suspect object terminals that transmit or receive the suspect object packets according to the object confirmation request message based on the information on the monitoring objects. When the suspect object terminals are the monitoring object terminals, the control server updates the database based on the information on the suspect object packets.

摘要： The present invention provides a traceback method including: receiving data including router information according to a path of an attacker; filtering the data to hash the data, and storing the resultant hashed information; determining whether the data is normally received on the basis of the hashed information; and predicting a path loss on the basis of the determination result. Therefore, it is possible to perform an accurate IP traceback using a probabilistic packing marking method and a hash-based traceback method.
