An explosively pumped flux compression generator ( EPFCG) is a device used to generate a high-power electromagnetic pulse by compressing magnetic flux using high explosive . An EPFCG only ever generates a single pulse as the device is physically destroyed during operation. They require a starting current pulse to operate, usually supplied by ...
A key generator [1] [2] [3] is a protocol or algorithm that is used in many cryptographic protocols to generate a sequence with many pseudo-random characteristics. This sequence is used as an encryption key at one end of communication, and as a decryption key at the other. One can implement a key generator in a system that aims to generate ...
KG-13 (PONTUS) The KG-13 Electronic Key Generator, Transmitter/Receiver was similar in appearance to the KG-14. This solid state design dating from the mid-to-late 1960s, originally cost $13,000 per copy. It was one of the first crypto machines to encrypt data such as facsimile. Crypto technicians received 10 to 12 weeks training on the machine.
The M202 FLASH ("Flame Assault Shoulder") [ 3] is an American rocket launcher manufactured by Northrop Corporation, designed to replace the World War II –vintage flamethrowers (such as the M1 and the M2) that remained the military's standard incendiary devices well into the 1980s. The XM202 prototype launcher was tested in the Vietnam War, as ...
Symmetric-key algorithms use a single shared key; keeping data secret requires keeping this key secret. Public-key algorithms use a public key and a private key. The public key is made available to anyone (often by means of a digital certificate). A sender encrypts data with the receiver's public key; only the holder of the private key can ...
The EFF's DES cracker "Deep Crack" custom microchip. In cryptography, the EFF DES cracker (nicknamed " Deep Crack ") is a machine built by the Electronic Frontier Foundation (EFF) in 1998, to perform a brute force search of the Data Encryption Standard (DES) cipher's key space – that is, to decrypt an encrypted message by trying every ...
The key selects which S-boxes are used. The patent describes the execution of the cipher operating on 24 bits at a time, and also a sequential version operating on 8 bits at a time. Another variant by John L. Smith from the same year [3] uses a 64-bit key operating on a 32-bit block, using one addition mod 4 and a singular 4-bit S-box. The ...
Fluxus is a live coding environment for 3D graphics, music and games. [1] It uses the programming language Racket (a dialect of Scheme/Lisp) to work with a games engine with built-in 3D graphics, physics simulation and sound synthesis. All programming is done on-the-fly, where the code editor appears on top of the graphics that the code is ...
