Software-defined Radio
Software-defined radio (SDR) is a radio communication system where components that have been traditionally implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system. While the concept of SDR is not new, the rapidly evolving capabilities of digital electronics render practical many processes which were once only theoretically possible. A basic SDR system may consist of a personal computer equipped with a sound card, or other analog-to-digital converter, preceded by some form of RF front end. Significant amounts of signal processing are handed over to the general-purpose processor, rather than being done in special-purpose hardware (electronic circuits). Such a design produces a radio which can receive and transmit widely different radio protocols (sometimes referred to as waveforms) based solely on the software used. Software radios have signif ...

Transceiver
In radio communication, a transceiver is an electronic device which is a combination of a radio ''trans''mitter and a re''ceiver'', hence the name. It can both transmit and receive radio waves using an antenna, for communication purposes. These two related functions are often combined in a single device to reduce manufacturing costs. The term is also used for other devices which can both transmit and receive through a communications channel, such as ''optical transceivers'' which transmit and receive light in optical fiber systems, and ''bus transceivers'' which transmit and receive digital data in computer data buses. Radio transceivers are widely used in wireless devices. One large use is in two-way radios, which are audio transceivers used for bidirectional person-to-person voice communication. Examples are cell phones, which transmit and receive the two sides of a phone conversation using radio waves to a cell tower, cordless phones in which both the phone handset and ...

Kickstarter
Kickstarter is an American public benefit corporation based in Brooklyn, New York, that maintains a global crowdfunding platform focused on creativity. The company's stated mission is to "help bring creative projects to life". As of July 2021, Kickstarter has received $6.6 billion in pledges from 21 million backers to fund 222,000 projects, such as films, music, stage shows, comics, journalism, video games, board games, technology, publishing, and food-related projects. People who back Kickstarter projects are offered tangible rewards or experiences in exchange for their pledges. This model traces its roots to subscription model of arts patronage, where artists would go directly to their audiences to fund their work. History Kickstarter launched on April 28, 2009, by Perry Chen, Yancey Strickler, and Charles Adler. ''The New York Times'' called Kickstarter "the people's NEA". ''Time'' named it one of the "Best Inventions of 2010" and "Best Websites of 2011". Kickstarter repo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU Radio
GNU Radio is a free software development toolkit that provides signal processing blocks to implement software-defined radios and signal processing, signal-processing systems. It can be used with external Radio frequency, RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic, and commercial environments to support both wireless communications research and real-world radio systems. Overview The GNU Radio software provides the framework and tools to build and run software radio or just general signal-processing applications. The GNU Radio applications themselves are generally known as "flowgraphs", which are a series of signal processing blocks connected together, thus describing a data flow. As with all software-defined radio systems, reconfigurability is a key feature. Instead of using different radios designed for specific but disparate purposes, a single, general-purpose, radio can be used as ...

Information Security
Information security, sometimes shortened to InfoSec, is the practice of protecting information by mitigating information risks. It is part of information risk management. It typically involves preventing or reducing the probability of unauthorized/inappropriate access to data, or the unlawful use, disclosure, disruption, deletion, corruption, modification, inspection, recording, or devaluation of information. It also involves actions intended to reduce the adverse impacts of such incidents. Protected information may take any form, e.g. electronic or physical, tangible (e.g. paperwork) or intangible (e.g. knowledge). Information security's primary focus is the balanced protection of the confidentiality, integrity, and availability of data (also known as the CIA triad) while maintaining a focus on efficient policy implementation, all without hampering organization productivity. This is largely achieved through a structured risk management process that involves: * identifying inform ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Hat Briefings
Black Hat Briefings (commonly referred to as Black Hat) is a computer security conference that provides security consulting, training, and briefings to hackers, corporations, and government agencies around the world. Black Hat brings together a variety of people interested in information security ranging from non-technical individuals, executives, hackers, and security professionals. The conference takes place regularly in Las Vegas, Barcelona, London and Riyadh. The conference has also been hosted in Amsterdam, Tokyo, and Washington, D.C. in the past. History The first Black Hat was held July 7-10, 1997 in Las Vegas, immediately prior to DEF CON 5. The conference was aimed at the computer industry, promising to give them privileged insight into the minds and motivations of their hacker adversaries. Its organizers stated: "While many conferences focus on information and network security, only the Black Hat Briefings will put your engineers and software programmers face-to-face ...

DEF CON
DEF CON (also written as DEFCON, Defcon or DC) is a hacker convention held annually in Las Vegas, Nevada. The first DEF CON took place in June 1993 and today many attendees at DEF CON include computer security professionals, journalists, lawyers, federal government employees, security researchers, students, and hackers with a general interest in software, computer architecture, hardware modification, conference badges, and anything else that can be "hacked". The event consists of several tracks of speakers about computer- and hacking-related subjects, as well as cyber-security challenges and competitions (known as hacking wargames). Contests held during the event are extremely varied, and can range from creating the longest Wi-Fi connection to finding the most effective way to cool a beer in the Nevada heat. Other contests, past and present, include lockpicking, robotics-related contests, art, slogan, coffee wars, scavenger hunt and Capture the Flag. Capture the Flag (CTF) is p ...

Security BSides
Security BSides (commonly referred to as BSides) is a series of loosely affiliated information security conferences. It was co-founded by Mike Dahn, Jack Daniel, and Chris Nickerson in 2009. Due to an overwhelming number of presentation submissions to Black Hat USA in 2009, the rejected presentations were presented to a smaller group of individuals. Over time the conference format matured and was released to enable individuals to start their own BSides conferences. The Las Vegas BSides conference is also considered part of Hacker Summer Camp given it's schedule and proximity to other security conferences during that time. There are three event styles, Structured, Unconference, and hybrid. A Structured event follows the traditional conference model and often happens in tandem with other larger conferences such as Black Hat, RSA, etc. Attendees typically intermingle and attend one or more events. Talks are submitted to the local event ahead of time, selected, and scheduled prior t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tactical Communications
Tactical communications are military communications in which information of any kind, especially orders and military intelligence, are conveyed from one command, person, or place to another upon a battlefield, particularly during the conduct of combat. It includes any kind of delivery of information, whether verbal, written, visual or auditory, and can be sent in a variety of ways. In modern times, this is usually done by electronic means. Tactical communications do not include communications provided to tactical forces by the Defense Communications System to non-tactical military commands, to tactical forces by civil organizations, nor does it include strategic communication. Early means The earliest way of communicating with others in a battle was by the commander's voice or by human messenger. A runner would carry reports or orders from one officer to another. Once the horse was domesticated messages could travel much faster. A very fast way to send information was to use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Positioning System
The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It does not require the user to transmit any data, and operates independently of any telephonic or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls and maintains the GPS system, it is freely accessible to anyone with a GPS receiver. The GPS project was started by the U.S. Department of Defense in 1973. The first prototype spacecraft was lau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
