노병규,김영태,박두순,김점구 한국융합보안학회 2005 융합보안 논문지 Vol.5 No.4

현재, ISO/IEC SC27 WG3에서는 공통평가기준 개발위원회(CCDB)를 주축으로 CC V3.0의 개정작업을 2008년까지 국제표준을 목표로 적극적으로 진행하고 있다. 따라서 CC V3.0의 변경내용을 분석하여 국가적 차원에서 CC V2.*에서 V3.0의 변화에 철저하게 대비할 필요가 있다. 이에 따라 본 논문에서는 현재 개정 중인 CC V3.0의 개선내용을 CC V3.0 개용내용 요약, 제1부-소개 및 일반모델 개정내용, 제2부-보안기능컴포넌트의 개정내용, 제3부-보안보증컴포넌트의 개정내용 등 크게 네 개의 영역으로 나누어 정밀분석하고 CC V3.0의 개선사항 및 변경내용에 대해 상세하게 설명한다. Recently, ISO/IEC SC27 WG3 is actively working on the revision of CC V3.0 to be an international standard by 2008, principally supported by Common Criteria Development Board (CCDB). Hence, it is essential for Korea to review and analyze the changes in CC V3.0, so as to be completely prepared for any change to be occurred from CC V2.* to V3.0. Taking into account of CC V3.0 being revised currently, this paper gives a general overview of revision in CC V3.0;then, closely examines and explains the improvements and changes made by the revision in CC V3.0

In this paper, multiheterostructure white organic light-emitting device was fabricated by vacuum evaporation. The structure of white organic light-emitting device is ITO/CuPc/TPD/DPBi:DPA/$Alq_3/Alq_3$:DCJTB/BCT/$Alq_3$/Ca/Al. Three primary colors are implemented with DPVBi, Alq$_3$and DCJTB. The maximum EL wavelength of the fabricated white organic light-emitting device is 647nm. And the CIE coordinate is (0.33, 0.33) at 13 V. In the fabrication of white organic light-emitting devices with DCJTB, $Alq_3$, DPVBi, the EL spectrum has two peaks at 492nm, 647nm. Two peaks appeared because the blue light is combined with green light. The maximum wavelength of red light is not changed with applied voltage. After voltage applied, for the first time, the electrons met the holes in the red emission layer and emitted red light. And then the electrons moved to the green emission layer, and blue emission layer continuously. Finally, when all of the emission layer activated, the white light is emitted.

Dynamic Control of Random Constant Spreading Worm using Depth Distribution Characteristics

노병규,홍민,이화민,박윤석,박두순 한국정보처리학회 2009 Journal of information processing systems Vol.5 No.1

Ever since the network-based malicious code commonly known as a 'worm' surfaced in the early part of the 1980's, its prevalence has grown more and more. The RCS (Random Constant Spreading) worm has become a dominant, malicious virus in recent computer networking circles. The worm retards the availability of an overall network by exhausting resources such as CPU capacity, network peripherals and transfer bandwidth, causing damage to an uninfected system as well as an infected system. The generation and spreading cycle of these worms progress rapidly. The existing studies to counter malicious code have studied the Microscopic Model for detecting worm generation based on some specific pattern or sign of attack, thus preventing its spread by countering the worm directly on detection. However, due to zero-day threat actualization, rapid spreading of the RCS worm and reduction of survival time, securing a security model to ensure the survivability of the network became an urgent problem that the existing solution-oriented security measures did not address. This paper analyzes the recently studied efficient dynamic network. Essentially, this paper suggests a model that dynamically controls the RCS worm using the characteristics of Power-Law and depth distribution of the delivery node, which is commonly seen in preferential growth networks. Moreover, we suggest a model that dynamically controls the spread of the worm using information about the depth distribution of delivery. We also verified via simulation that the load for each node was minimized at an optimal depth to effectively restrain the spread of the worm.

In this paper, the single and double heterostructure organic light-emitting devices(OLEDs) were fabricated. The single heterostructure OLED(TYPE 1) is consisted of TPD as a HTL(hole transfer layer) and Alq$_3$as an EML(emitting layer). The double heterostructure OLED(TYPE 2) is consisted of TPD as a HTL, Alq$_3$as an EML and PBD as an ETL(electron transfer layer). The another double heterostructure OLED(TYPE 3) is consisted of TPD as a HTL, PBD as an EML and Alq$_3$as an ETL. We obtained a strong green emission device with maximum EL emission wavelength 500nm in TYPE 3. When the applied voltage was 12V, the emission luminescence was 120.9cd/㎡. The chromaticity index of TYPE 3 was x=0.29, y=0.50. In the characteristic plot of current-voltage, TYPE 3 device was turned on at 6.9V. This voltage was a fairly low turn-on voltage. TYPE 1 and 2 device were turned on at 10V and 8.9V respectively. These types showed no good properties over that of TYPE 3.

1MeV 인 이온 주입시 RTA에 의한 미세결함 특성과 latch-up 면역에 관한 구조 연구

노병규,윤석범,Roh, Byeong-Gyu,Yoon, Seok-Beom 한국전기전자학회 1998 전기전자학회논문지 Vol.2 No.1

인(Phosphorus)을 1MeV로 이온 주입한 후 RTA를 실시하여 미세결함의 특성을 조사하고, 면저항, SRP, SIMS, XTEM 분석과 CMOS 구조에서 래치업 특성을 모의 실험하였다. 도즈량이 증가할수록 면저항은 낮아지고, Rp값은 도즈량이 $1{\times}10^{13}/cm^2,\;5{\times}10^{13}/cm^2,\;1{\times}10^{14}/cm^2$일때 각각 $1.15{\mu}m,\;1.15{\mu},\;1.10{\mu}m$로 나타났다. SIMS 측정결과는 열처리 시간이 길수록 농도의 최대치가 표면으로부터 깊어지고, 농도 또한 낮아짐을 확인하였다. XTEM 분석 결과는 열처리 전에는 결함측정이 불가능했으나, 측정되지 많은 미세결함이 열처리 후 이차결함으로 성장한 것으로 조사되었다. 모의 실험은 buried layer와 connecting layer 구조를 사용하였으며, buried layer보다 connecting layer가 래치업 특성이 우수함을 확인하였다. Connecting layer의 도즈량이 $1{\times}10^{14}/cm^2$이고 이온주입 에너지가 500KeV일 때 trigger current는 $0.6mA/{\mu}m$이상이었고, trigger voltage는 약 6V로 나타났다. Connecting layer의 이온주입 에너지가 낮을수록 래치업 저감효과가 더욱 우수함을 알 수 있었다. This paper is studied micro-defect characteristics by phosphorus 1MeV ion implantation and Rs, SRP, SIMS, XTEM for the RTA process was measured and simulated. As the dose is higher, the Rs is lower. When the dose are $1{\times}10^{13}/cm^2,\;5{\times}10^{13}/cm^2,\;1{\times}10^{14}/cm^2$, the Rp are $1.15{\mu}m,\;1.15{\mu},\;1.10{\mu}m$ respectively. As the RTA time is longer, the maximum concentration position is deeper from the surface and the concentration is lower. Before the RTA was done, we didn't observe any defect. But after the RTA process was done, we could observe the RTA process changed the micro-defects into the secondary defects. The simulation using the buried layer and connecting layer structure was performed. As results, the connecting layer had more effect than the buried layer to latch-up immune. Trigger current was more $0.6mA/{\mu}m$ and trigger voltage was 6V at dose $1{\times}10^{14}/cm^2$ and the energy 500KeV of connecting layer Lower connecting layer dose, latch-up immune characteristics was better.
