[DEFCON 16] Bypassing pre-boot authentication passwords by instrumenting the...Moabi.com
Pre-boot authentication software, in particular full hard disk encryption software, play a key role in preventing information theft. In this paper, we present a new class of vulnerability affecting multiple high value pre-boot authentication software, including the latest Microsoft disk encryption technology : Microsoft Vista's Bitlocker, with TPM chip enabled. Because Pre-boot authentication software programmers commonly make wrong assumptions about the inner workings of the BIOS interruptions responsible for handling keyboard input, they typically use the BIOS API without flushing or initializing the BIOS internal keyboard buffer. Therefore, any user input including plain text passwords remains in memory at a given physical location. In this article, we first present a detailed analysis of this new class of vulnerability and generic exploits for Windows and Unix platforms under x86 architectures. Unlike current academic research aiming at extracting information from the RAM, our practical methodology does not require any physical access to the computer to extract plain text passwords from the physical memory. In a second part, we will present how this information leakage combined with usage of the BIOS API without careful initialization of the BIOS keyboard buffer can lead to computer reboot without console access and full security bypass of the pre-boot authentication pin if an attacker has enough privileges to modify the bootloader. Other related work include information leakage from CPU caches, reading physical memory thanks to firewire and switching CPU modes.

Counter strike global offensive requirementszain hayat
Counter Strike Global Offensive system reqirements are not as high as people think they are. It takes an average system to run the game. CSGO is undoubtedly the most played combat game on this planet. It generally gives a notion of high system reqirements, but realistically this is not the case at all. Counter Strike Global Offensive system requirements for windows, Mac os X and steam OS+Linux are discussed in this presentation.

Computer networks have become part of our everyday lives. We use them to take cash from the local ATM. Whenever we send email or browse the Web, we rely on the world’s largest computer network, the Internet, to be our electronic mailman. Telemarketers, usually during dinner hour, use computer networks to sell us their wares. Our cable television stations rely on computer networks to transport programs onto our TV screens. What is a compelling example of their presence in our lives? Without computer networks, our cellular phone is little more than a battery powering-up a meaningless screen. Read more.........

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
