When FPGAs attack hashes

What could you do with an array of 15 FPGAs? Why not attack hashes! NSA@home is a fast FPGA-based SHA-1 and MD5 bruteforce cracker. It is capable of searching the full 8-character keyspace (from a 64-character set) in about a day in the current configuration for 800 hashes concurrently, using about 240W of power. The […]

Falling sand game on FPGA

Skyler Schneider at Cornell University has produced a very comprehensive description of a falling sand game project using an Altera Cyclone II on the DE2 dev board. The Verilog source code listings demonstrate the level of coding required to produce dynamic video representations in a gaming environment. Via Hack a Day. Schneider’s project is a […]

Implementation of DES algorithm using FPGA technology

Arnaud Lagger has published some interesting work on the use of FPGAs in encryption. Unlike other docs we’ve seen, this analysis is both comprehensive and detailed, including an appendix with the VHDL source code. Definitely worth the read for anyone interested in encryption using FPGAs.

Logic Sniffer upgrade v2.1 released

Package v2.1 is the first official upgrade release for the Logic Sniffer. Download it now at the Gadget Factory. This version has a lot of updates that should fix a bunch of problems in the initial release: FPGA bitstream v2.1 with high-speed SPI connection between the PIC and FPGA. This eliminates most ‘hardware not found’ […]

Logic Sniffer upgrade procedure

This is an old version, see the latest version on the documentation wiki. The Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. This project is a collaboration between the Gadget Factory and Dangerous Prototypes. The Logic Sniffer has two parts that […]

“Logic Analyzer in a Day” Experts’ Challenge

Development board manufacturer Opal Kelly has invited three FPGA experts to design logic analyzers. Each participant has 8 to 10 hours to complete a design, the final designs will be posted online. The analyzer will be built with Opal Kelly’s modules and software development kit, but there might be some interesting takes on a common […]

Open source logic analyzer development

We’re really excited to be joined by Jack Gassett, developer of the Butterfly FPGA platform, to prototype an open source, high-speed, low-cost logic analyzer. This effort grew out of a bunch of great comments on a post about open source logic analyzer clients. Share your ideas for the logic analyzer in the new ‘SUMP PUMP’ […]

$49 FPGA development board

Field programmable gate arrays often separate the professionals from the hobbyists. Development tools are expensive, and the chips are usually in high pin-count BGA surface mount packages. Totti turned us on to a $49 Spartan-3A FPGA development kit from AVNET. It’s got a large Xilinx Spartan FPGA, two types of flash memory, and four capacitive […]
