Forensics on GPUs

From Forensics Wiki
Jump to navigation Jump to search

Using a Graphical Processing Unit (GPU) for forensics analysis attempts to make use of the significant, parallel processing power available on these high cards for a different purpose than their original intent. The idea of forensic analysis on a GPU was first proposed by Marziale, Richard and Roussev in 2007 with a version of Scalpel that utilized a GPU.

Password Cracking

Password cracking process accelerated by using GPU is several times faster than in CPU-only mode.

For example, password recovering speed for MD5 hash using Core2 Duo is about 4,7 millions passwords per second. By using 8800GTX it is possible to reach 265 millions passwords per second.
