Yeah, this is still a form of brute force but I was thinking of this in terms of a smallish (sub 200 bit) key, so brute force against solutions with 0 entropy is a realistic possibility. anyone else got a faster way to attack this highly theoretical, will-never-be-implemented, type system?? I`d imagine there is some sort of way to measure the entropy "mixed in" by the XOR thus giving a foothold in the key, but I can`t think of anything right now, anyone got any ideas?

Eudora 3.0 supports multiple tentacles
by Greg Broiles 17 Dec '03

17 Dec '03

Those of you who have or are tentacles (hee, hee) might take a look at the new Eudora 3.0 beta; it's got nice built-in support for multiple POP mailboxes/usernames, and keeps track of which identity received a messages, and sends replies from that identity (using the appropriate outbound SMTP server) so as not to confuse correspondents. It seems to be ideally set up for people who want to adopt an alternate nym for whatever reason. The filtering is also allegedly improved but I haven't fussed with that much yet. -- Greg Broiles | "We pretend to be their friends, gbroiles(a)netbox.com | but they fuck with our heads." http://www.io.com/~gbroiles | |

Hmm. The government sure is putting a lot of effort into moving us to a system that you say is "no different than the system we have today." As far as I can tell, you're the only one who thinks that. The government thinks that GAK is a big change, civil libertarians think GAK is a big change .. but you're welcome to call it "status quo" if it suits you. There's a world of difference between the government subpoena-ing something from me, where I can delay disclosure until I've exhausted my legal avenues to challenge disclosure, and the government demanding data from an at best disinterested third party who cares not at all if I get my day in court before they disclose. With the second scenario, I'm forced to try to "unring the bell", and somehow limit the spread of otherwise private/confidential data in a community (law enforcement) which is organized to collect and retain information. Ha, ha. Given today's Congress and Supreme Court, there's probably precious little chance that keys disclosed prematurely or erroneously won't be used to collect evidence which will be admissible despite the lack of meaningful opportunity to challenge the "recovery" of a key. -- Greg Broiles | "We pretend to be their friends, gbroiles(a)netbox.com | but they fuck with our heads." http://www.io.com/~gbroiles | |

No DNA required. Sorry Unicorn, you missed my point. (1) You need DNA to grow bacteria. You can get the DNA two ways.

Something like > "Key Recovery System." You heard it here.) I agree, and hope so. "Key Recovery," while not as Orwellian-sounding as "GAK," is a step on the path to honesty WRT the English language, though it's important to continually point out, as Tim did in his post, that *access* -- rather than just recovery -- is obviously what Mr. Freeh wants.
