Title: Ｔｃｐ ｓｙｎ 플러딩 공격을 좌절시키기 위한 방법 및시스템
IPC: H04L29/06
Filed: 2001-04-19
Abstract: TCP SYN 플러딩 공격을 좌절시키기 위한 방법 및 시스템이 개시된다.  TCP를 실행하는 서버에서, SYN 메시지를 수신할 때마다, 서버는 ISR을 계산하여 이를 클라이언트로의 SYN-ACK 응답내에 포함시킨다.  서버는 클라이언트로부터 ACK 메시지가 수신되는 지를 청취하여 ISR을 검증한다.  검증을 통과하지 못하면, ACK 메시지는 폐기된다.  검증을 통과하면, ISR은 진정한 계산된 ISR로 수용되며 이에 따라 디코딩된다.  이 경우에만, 자원이 할당되며 TCP 접속이 실제로 확립된다.  그 후에, 청취 상태로 복귀하여 모든 수신되는 TCP 메시지들을 계속 처리한다. 
     본 발명에 의하면, 클라이언트가 실제로 정규의 TCP 3-웨이 핸드 세이킹 과정을 완료한 때에만 TCP 접속을 위한 서버 자원을 할당하도록 되어 있어, DoS 및 DDoS 공격에 의해 생성된 반개방 접속들이 서버 자원을 독차지 하는 것을 방지한다.

Title: Air cooling method of sprue and runner in plastic injection method and apparatus thereof
Inventor: JUNG GWANG GI
IPC: B29C45/73
Filed: 2001-06-22
Abstract: Dopant atoms have coefficients of diffusion that vary in the presence of implant damage. Dopant atoms preferably diffuse to damaged regions. Damaged regions are created to accumulate selected dopants during thermal cycling by implanting silicon atoms into a silicon substrate prior to formation of a gate electrode. The damaged regions are formed to accumulate dopants in selected regions for purposes including threshold control for a field device, threshold setting for a transistor, and prevention of device punchthrough. Dopant is preferentially accumulated by formation of damaged regions to set particular selected electrical properties without placing an excessive amount of dopant in regions adjacent to junctions. Transistor dopant concentrations are controlled by implanting silicon prior to formation of a gate electrode to induce transient-enhanced diffusion (TED) of dopant atoms. Transient-enhanced diffusion improves the doping of a substrate by enhancing the diffusion of dopants at relatively low anneal temperatures. Silicon is implanted in a silicon substrate to form damaged regions in the substrate that act as a getter for attracting selected dopants that are trapped in the silicon substrate. Three dopant implant operations, including a threshold voltage VTadjusting implant, a punchthrough prevention implant and a well-formation implant, are performed to act as a getter for the dopant implants of three dopant implant operations. The well-formation implant is implanted essentially uniformly beginning at the substrate surface and extended at a predetermined well depth. The VT adjusting implant is implanted near the substrate surface and extending only a shallow depth into the substrate. The punchthrough prevention implant is implanted at a depth greater than the VTadjusting implant to inhibit current flow beneath a device channel.
