Traffic Analysis

I'm curious about traffic analysis capability. While I don't know the exact figures involved, I'd say that Cracker throws away about 10% of the messages it receives. Admittedly, these are probably not encrypted messages (I don't know. Humans do not get to read the messages.) Does this make traffic analysis more difficult? On the other side, if Cracker were to send out more messages that it takes in, or just replace these thrown away messages with random noise messages, perhaps encrypted, would this foil traffic analysis? Or suppose Redneck sent each nym an encrypted message each day, or more often? This would be a pure nonsense message just sent out to foil traffic analysis. Since the server generated the nonsense message internally, there would be no matching incoming message for Redneck. -- Robert Costner Phone: (770) 512-8746 Electronic Frontiers Georgia mailto:pooh@efga.org http://www.efga.org/ run PGP 5.0 for my public key

THE CLASSIC MIDDLE NAME (continued) * In Alabama, murderer Billy Wayne Waldrop was executed in January, and the next month, murderer Dudley Wayne Kyzer was turned down for parole. Two weeks later, murderer Coleman Wayne Gray was executed in Virginia. In May, murderer Larry Wayne White was executed in Texas. In July, Maryland inmate Richard Wayne Willoughby was sentenced to life in prison for killing another inmate. And once again this April 19, the nation was reminded that the Oklahoma City bombing date commemorated not only the seige at Waco, but the 1995 Arkansas execution of murderer and militia hero Richard Wayne Snell. AUTHENTICITY: All news stories mentioned in News of the Weird are from news stories appearing in daily newspapers in the U. S. and Canada (or occasionally, reputable daily newspapers in other countries or other reputable magazines and journals). No so-called supermarket tabloid, and no story that was not intended to be "news," is ever the source of a News of the Weird story.

Of course not: - it provides even more non-covered traffic for Mallet to analyze - it proves that the remailer is keeping long-term records of its activity, further prompting Mallet to use rubber-hose crypto or a covert break-in to recover the data. A commercial remailers should keep no records and this means that each submission must include some form of token for immediate payment of access fees. Further, a secure remailer should NEVER send traffic to a subscriber as the result of anything other than normal traffic handling. ____________________________________________________________________ | | | The financial policy of the welfare state requires that there | | be no way for the owners of wealth to protect themselves. | | | | -Alan Greenspan- | | | | _____ The Armadillo Group | | ,::////;::-.

Traffic analysis generaly does not look at the contents of the packets, encrypted or not is irrelevant. I suspect it would lower the estimated ratio of cover traffic if nothing gets sent out. This would in general lower the cost to analyse the traffic. I would set it up to send bogus outgoing even if the message was dropped. That way the analysis would correlate the dropped message to the outgoing and produce a cover ratio closer to the actual value. Also remember to send n+1 bogus traffic to make up for the dropped outgoing. > Or suppose Redneck sent each nym an encrypted message each day, or more > often? By 'nym' you mean each subscribed address or to each address used in the outgoing? I would say it is bad to send to subscribers. It provides non-covered traffic that identifies your subscribers specificaly (really not a threat since Mallet already has their original incoming and therefore their source address) as well as demonstrating that you are keeping long-term traffic records. The long-term records represent a clear threat to the security and stability of the remailer. If you send out this cover traffic regularly then be shure to use some mechanism to select email addresses randomly or else Mallet will get a list of your bogus addresses and begins to filter them immediately. A commercial remailer should not keep records of its use. However, I suspect that eventualy remailers will be required to keep usage records by law. ____________________________________________________________________ | | | The financial policy of the welfare state requires that there | | be no way for the owners of wealth to protect themselves. | | | | -Alan Greenspan- | | | | _____ The Armadillo Group | | ,::////;::-.

CNN logo Navigation Infoseek/Big Yellow Pathfinder/Warner Bros Main banner Move the corporate ladder to your back yard. Because you can. VAIO/Sony rule JUDGE THROWS OUT RUBY RIDGE CHARGES Randy Weaver's house October 2, 1997 Web posted at: 8:36 p.m. EDT (0036 GMT) Latest developments: * Judge invokes double-jeopardy law * Harris accused of killing U.S. marshal * Charges against FBI agent unaffected BONNERS FERRY, Idaho (CNN) -- An Idaho judge dismissed a state murder charge against a man accused of killing a federal agent in the Ruby Ridge shootout, saying he can't be tried again after his acquittal of murder in federal court. Idaho Magistrate Judge Quentin Harden ruled Thursday that the charge against Kevin Harris violate a state law barring prosecution of someone who faced the same charges in another "state, territory or country." Prosecutor Denise Woodbury, who charged Harris and FBI marksman Lon Horiuchi in state court in August, had argued that the state double-jeopardy law was meant to cover prosecutions in other countries, not the United States. "I find that (Idaho law) bars further prosecution of Kevin Harris for the acts set forth ... in the complaint in this case," Harden said. "To rule that the courts of the United States of America do not come under 'another state, territory, or country' would be an anomalous result -- giving more credence to the courts of another country than to the courts of our own nation," Harden wrote. Harris accused of killing U.S. marshal Standoff scene Harris, 29, of Republic, Washington, was accused in the shooting death of deputy U.S. Marshal William Degan and of shooting at another agent in the August 21, 1992, shootout that precipitated an 11-day siege at the cabin of white separatist Randy Weaver. A friend of Weaver's, Harris was staying at the cabin during the shootout and was wounded by an FBI sniper's bullet. Weaver's 14-year-old son, Sam, was killed in the gunfight. His wife, Vicki Weaver, was later shot and killed during the siege by the FBI's Horiuchi. The shootout has become a rallying point for some groups who believe federal law enforcement has encroached too much on citizens' rights. Weaver and Harris were tried and acquitted of federal charges in 1993. But in August, Woodbury charged Harris with first-degree murder in Degan's death and assault with a deadly weapon against Arthur Roderick, another law enforcement officer. Harden also dismissed the assault charge. Woodbury also charged Horiuchi with involuntary manslaughter in the death of Vicki Weaver. Charges against FBI agent unaffected Harden's ruling doesn't affect the charge against Horiuchi, who has never been tried in any court. His lawyers have indicated they will try to move his case to a federal court. Harris was at his job as a welder when he received the news that the murder charge against him had been dismissed, said Diane Peters, his business partner at Eagle Industries. "We were hoping what was fair and just would turn out," Peters said. Harris himself did not return a phone call, and Woodbury declined to comment on Harden's ruling.

One nice feature is that there doesn't need to be a standardized payment arrangement with all remailers, just the one you use for your entry point. And, there's nothing that prevents many remailer networks from overlapping. (Actually, the geometry could create some neat problems.) This would be fairly easy to set up, not even really needing client software modifications. However, it does have a "commons" problem. No remailer operator has an incentive to provide really good service. They are all encouraged to provide the bare minimum remailer service and take advantage of the other remailers in the network. For example, what would encourage somebody to have a 24 x 7 remailer service with continuous staffing? This would be desirable because when the bad guys kick down the door, there is somebody awake to pull the plug. There are a zillion other features which won't happen if there isn't a proper incentive.
