Security Dynamics

Re: security dynamics One could perform an interesting test with one of these Security Dynamics card. Aim a video camera at the LCD display so that the display takes up the full width of the image. Hook the video signal up to a digitizer board, and recognize the numbers that appear on the face. Spit them out as often as they appear. For someone with all the equipment, this should be a one or two evening hack. Now, if the number changes every minute, that's a little over 10,000 samples in a week, certainly enough to determine if they are using weak random number generation. I'll put the data on the ftp site, should anyone actually do this. Eric
