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.

A lawful interception apparatus, a lawful interception target apparatus and a lawful interception system are provided. If a lawful interception target apparatus accesses a new communication network which has no lawful interception authority, the lawful interception apparatus receives intercept activation information from the lawful interception target apparatus through a communication network which has a lawful interception authority. The lawful interception apparatus performs seamless lawful interception on the lawful interception target apparatus by use of the received intercept activation information.

A pouch type secondary battery, in which a bent state of a cathode tap and an anode tap is maintained by eliminating a restoration phenomenon caused by an elastic force of the insulating tape when the cathode tap and the anode tap are bent by forming bending grooves on cathode and anode insulating tapes, includes: an electrode assembly which includes a cathode electrode plate where a cathode tap is connected, a anode electrode plate where an anode tap is connected, and a separator interposed between the cathode electrode plate and the anode electrode plate; a pouch containing the electrode assembly therein such that the cathode tap and the anode tap are exposed to the outside; a cathode insulation tape forming a first bending groove on at least one side portion and wrapped around the cathode tap so as to insulate a region where the cathode tap is in contact with the pouch; and an anode insulation tape forming a second bending groove on at least one side portion and wrapped around the anode tap so as to insulate a region where the anode tap is in contact with the pouch.
摘要:
A pattern matching system detects strings contained in a target pattern to be detected within a data stream input by 1-byte data, and detects a regular expression representing the target pattern among regular expressions constructed by the detected strings.

A lawful interception apparatus of a service providing system inquires of a trust server in which a law execution server commissions lawful interception authority whether a terminal that connects to a service connection point is an interception target, determines whether a terminal that connects to a service connection point is an interception target, and if a terminal that connects to a service connection point is an interception target, and the lawful interception apparatus intercepts communication traffic that is related to the terminal.
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.

An apparatus and method for checking validity of an 8B/10B code-group are provided. The apparatus for checking validity of an 8B/10B code-group includes a 6B/5B disparity classification unit, a 4B/3B disparity classification unit, an RD6 detection unit, an RD4 detection unit, an 8B/10B code-group rule violation detection unit, an RD error detection unit, and a unit for outputting 8B/10B code-group validity. The apparatus receives an 8B/10B code-group, divides into a least significant 6-bit nibble and a most significant 4-bit nibble, detects a running disparity, and by doing so, determines the validity of a code-group. The apparatus and method for checking validity of an 8B/10B code-group relatively shortens the critical path, which indicates the number of combinational logic circuits that should be operated in a unit time, and therefore the apparatus and method are appropriate to high-speed systems such as gigabit Ethernet systems.
