An apparatus and method of using near field communication (NFC) and wireless power transmission (WPT) are provided. A power receiving apparatus includes a resonator configured to receive a power and to output the power. The power receiving apparatus further includes a near field communication (NFC) receiver configured to perform wireless communication using the power output by the resonator. The power receiving apparatus further includes a wireless power transmission (WPT) receiver configured to supply a voltage using the power output by the resonator. The power receiving apparatus further includes a connecting unit configured to selectively connect the resonator to either the NFC receiver or the WPT receiver. The power receiving apparatus further includes a mode selector configured to control the connecting unit to selectively connect the resonator to either the NFC receiver or the WPT receiver based on the power output by the resonator.

A flip chip package includes a substrate and a semiconductor chip. The substrate includes a substrate body, a metal wiring having a terminal part some of which is disposed in the substrate body, a solder resist pattern formed on the substrate body with an opening for exposing the terminal part, and an organic anti-oxidation layer for covering the terminal part. The semiconductor chip has a bump formed through (e.g., penetrates) the organic anti-oxidation layer and is electrically connected to the terminal part. The present invention prevents oxidation of the terminal part and allows easy coupling of a bump of a semiconductor chip and the terminal part of the substrate, since an anti-oxidation layer including an organic matter is formed over a surface of a terminal part including copper which is easily oxidized.

An apparatus and method for performing packet header lookup based on sequential lookup is provided. A header analyzer separates a header from a packet received via a network and outputs a lookup sequence. A unit lookup unit looks up matching the header combination rules with each field to be analyzed and input from the header analyzer based on the lookup sequence input from the header analyzer and outputs a match signal and a match address. A rule combination memory stores identification information for the header combination rules. A sequence combination memory stores lookup sequence information and sequence combination information. A rule combination unit generates match results based on the match signal input from the unit lookup unit and data read from the rule combination memory and the sequence combination memory.

An alert transmission apparatus for a policy-based intrusion detection and response has a central policy server (CPS) and an intrusion detection and response system (IDRS). In the CPS, a policy management tool generates security policy information and then stores the generated security policy information in a policy repository. A COPS-IDR server sends the information to the IDRS and an IDMEF-XML-type alert transmission message to a high-level module. An IDMEF-XML message parsing and translation module stores a parsed and translated IDMEF-XML-type alert transmission message in an alert DB or provides the message to an alert viewer. In the IDRS, a COPS-IDR client generates the IDMEF-XML-type alert transmission message and provides the message to the CPS. An intrusion detection module detects an intrusion. An intrusion response module responds to the intrusion. An IDMEF-XML message building module generates an IDMEF-XML alert message and provides the message to the COPS-IDR client.
摘要:
An apparatus and method for detecting an attack packet in Internet Protocol version 6 (IPv6) are provided. The apparatus includes a control unit, a preprocessing unit, an attack determining unit, and a packet processing unit. The control unit sets a rule for attack determination and a rule for processing of an attack packet. The preprocessing unit decodes an IPv6 packet and a tunneling packet, and divides the decoded packet into each header and payload. The attack determining unit determines possibility of attack of the divided packet according to the rule for attack determination by using information of the divided packet. The packet processing unit performs at least one function of packet filtering, packet deleting, packet forwarding, and intrusion alarming according to a result of the determination of the attack determining unit, and the rule for processing of an attack packet.
