-----BEGIN PGP SIGNED MESSAGE----- Re: NOISE.SYS Random Sampling Device Driver for DOS (v0.2-Beta): I've finally gotten a usable version of NOISE.SYS written. The beta is ready for semi-public release and review. If you're interested in testing it or examing the code, email me at <wlkngowl@unix.asb.com> It's only a prototype version. I do not know any strong methods of testing random data. If anyone is willing to help on that part or point me in the right direction, it would be appreciated... What this driver does: When loaded, it hooks onto the keyboard interrupt (0x09) and collected fast timings between keystrokes. It can also be easily configured at compilation to sample other interrupts, as well as collect "seedling" keystrokes upon initialization. It sets up a character device called RANDOM, that when polled takes the earliest collected bytes from the random pool (size can be adjusted), combines them with a count-word based on the number of samples collected plus the number of times the driver has fetched data from the pool, transforms it using the Secure Hash algorithm, and outputs the bits from the hash. It's only a prototype: this version doesn't check to see if the pool is "empty" at the moment. Features: written in 386 assembler, takes under 2k of memory and can be loaded from the command line using a utility like DEVLOD. Also under GPL, so you've got the source-code to play with. Comments and criticism from crypto-gurus would be greatly appreciated. Reply if you'd like me to send a copy. (Important Q: is this software covered under ITAR?!?) - --Rob <wlkngowl@unix.asb.com> -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBMOL8gNscUKerH0gxAQHNlAP/eZChSaAEg3go/vxfm9Z0Af5Dfa4WBDhh SfbbpsYfymSkxFbU7bHUfRMFHk+Uy57AeGMUxXkgml7KO8cxyOPS6yVDcNWf6Z9W OeXtXRAFBWRn3CblT1sQzl5YCEG93YBZS9ZkbTsN4rgTcpo15QY8vG5BJCEgfP9f 9XHn5VGSkVo= =jaNN -----END PGP SIGNATURE-----
