15)From: SpyKing(a)thecodex.com Subject: Re: Deadly Physical Force This thread might be getting tired but I ran across something that is applicable. I make no judgement on who is right or wrong. I was not there and only those who were know the truth. I'm posting this to show that despite being acquitted in one court the shooter in this case is being charged and brought to trial in another court on similiar charges. Some will scream double jeapordy and others will say justice is prevailing. The jury will have to decide... but I'll say one thing... If this guy IS convicted the rules of engagement change forever... SWAT teams will have to think twice before firing into dwellings... FBI sniper ordered to stand trial in Ruby Ridge case BONNERS FERRY, Idaho (Reuters) - An FBI sharpshooter has been ordered to stand trial on charges of involuntary manslaughter over the 1992 standoff at Ruby Ridge, Idaho, in which three people died, prosecutors said Wednesday. Idaho Magistrate Quentin Harden ruled there was enough evidence to allow the sharpshooter, Lon Horiuchi, to face trial on charges he acted with negligence when he fired a shot that killed the wife of white separatist Randy Weaver at his cabin. The standoff near Weaver's cabin turned into a rallying cry for extreme right-wingers who condemned what they saw as federal government excesses and held up Weaver as a hero. Boundary County prosecutor Denise Woodbury last August charged Horiuchi and Weaver's friend Kevin Harris with the deaths of two people killed in the standoff. The charges against Harris were later dismissed on the grounds that he had already been acquitted of those charges in federal court. In filing charges against Horiuchi, Woodbury accused the sharpshooter of using a gun in a reckless manner by firing through the front door of Weaver's house without first determining whether anyone other than his intended target was behind the door. Horiuchi could face up to 10 years in prison if convicted. The standoff began Aug. 21, 1992, when U.S. Marshals approached Weaver's cabin to arrest him for failing to appear in court on gun charges. U.S. Marshal William Degan and Weaver's 14-year-old son Sammy were killed in a gun battle near the cabin, and the Federal Bureau of Investigation was called in later that day. The next day, Horiuchi wounded Weaver and Harris and killed Vicki Weaver. Weaver and Harris surrendered 10 days later and were acquitted of murder charges in the killing of Degan in a 1993 federal trial. Weaver said in a telephone interview from his home in Montana that he was pleased by Harden's ruling. ``It's taken a long time, but sometimes the wheels of justice grind slowly. We are looking to see some justice in all of this,'' Weaver said. ``To be honest I hope that he (Horiuchi) eventually sees that he is just one of two scapegoats and that eventually he will tell the whole truth.'' Horiuchi's lawyers were due to appear next Monday before a federal judge in Boise to ask that the case against the FBI sniper be moved to federal court. Horiuchi was scheduled to be arraigned Friday, Feb. 13, in Idaho district court in Boundary County, but that could change if his case is remanded to federal court. Neither Horiuchi's lawyers nor Woodbury were immediately available for comment on Harden's ruling. 16)From: SpyKing(a)thecodex.com Subject: Germany to restore bugging Thursday January 8, 1:58 PM GMT Germany to restore bugging banned since Nazi-era BONN, Jan 8 (Reuters) - German political leaders agreed on Thursday to allow police to bug apartments of suspected criminals, restoring a crime-fighting tool banned since abuses by the secret police in the Nazi era. Leaders from Chancellor Helmut Kohl's centre-right coalition and the opposition Social Democrats (SPD) said they had reached a deal allowing police to plant microphones in private homes of suspected criminals for the first time since 1945. Both houses of parliament are now expected to quickly pass the long-debated measure, which police have argued was needed to better fight organised crime and bring the country in line with other nations that allow electronic surveillance. Germany, which reacted to the Gestapo's abuses with some of the Western world's most extensive civil liberties laws, has long resisted any relaxation in constitutional protections that have kept police out of private homes. Interior Minister Manfred Kanther said the agreement would give police the necessary tool to fight organised crime. "This is a decisive step towards more effectively fighting crime," Kanther said. "We can now keep surveillance on suspected gangster apartments and we will be able to better fight money laundering." The opposition SPD, which controls the upper house of parliament, the Bundesrat, said it would support the measure after the government agreed to partial exemptions for some professional groups such as priests, attorneys and journalists. Police will be required to obtain advance court permission for any surveillance. Previously, police were only given rare exemptions to the constitutional law protecting the private home. They were allowed to use listening devices or electronic surveillance only with court permission if there was concrete evidence that a serious crime was about to take place. Now authorities will have the power to use eavesdropping methods far more extensively and will also for the first time be able to bug apartments after a crime has been committed to obtain evidence. Germany's post-war constitution barred police from electronic surveillance, telephone taps and intercepting mail. The bans on telephone taps and mail intercepts were relaxed in the 1970s amid a wave of left-wing guerrilla attacks.

Einstein quotes

I thought I'd share these quote... The one quote that I found really funny is the one where Einstein says that had he known he would have been a locksmith. At some point after he came to the US somebody asked him what he would have been if he hadn't taken up physics. His reply was a plumber. He was promptly made an honorary member of the national plumbers union.

Batch DSA
by Anonymous 17 Dec '03

17 Dec '03

Batch DSA Amos Fiat invented a way to do multiple RSA signatures using only one full-sized exponentiation [J Cryptology v10 n2 p75]. The trick is to sign each one with a different RSA key, where the keys all share the same modulus n but differ in their public exponents e. A similar technique allows DSA signatures to be batched. As with Batch RSA, each message ends up being signed with a different DSA key, where the keys share the same p, q, and g values, but differ in their public y values, where y = g^x mod p for a secret x. These techniques may be useful for situations where heavily loaded servers need to digitally sign many responses. A DSA signature on a message M (where M is the hash of the actual data) is done as follows: Choose a random value k. k must be different for every signature. Calculate R = g^k mod p mod q. Calculate S from S*k = M + R*x mod q. Then (R, S) is the signature. The time consuming part of this is the calculation of g^k. This is the only exponentiation which must be done. All the other calculations can be very fast. We can't re-use a k value because it allows x to be discovered very easily. If two signatures (R, S_1) and (R, S_2) use the same k value, we have (mod q): S_1*k = M_1 + R*x S_2*k = M_2 + R*x The capitalized values are known, the lower case k and x are the unknowns. We have two equations in two unknowns, which allows us to recover k and x. If different x values are used for each signature, then it should be safe to re-use k. This is how Batch DSA would work. The signer would publish his public key as p, q, and g as usual, but now he would publish multiple y_i = g^x_i values. The convention is that any message is considered signed by the key if it is signed by any of the y_i. To sign a batch of messages, one k value is used for all of them. The same calculation as above is used: R = g^k mod p mod q (same for all) S_i * k = M_i + R * x_i mod q The signature is (R, S_i, i), where the index i is included to tell the verifier which y_i to use. This is not vulnerable to the problem above of re-using k. The multiple signatures have the relationships: S_1*k = M_1 + R*x_1 S_2*k = M_2 + R*x_2 S_3*k = M_3 + R*x_3 ... We always have more unknowns than there are equations, which hides the values of k and x_i. This same technique can be applied to most other discrete log signatures, which generally have the same structure although they differ in the details of how x and k are used to construct R and S. With Batch RSA, there is a tradeoff between batch size and efficiency. The calculations become inefficient for batch sizes larger than tens of messages when keys are about 1K bits. Batch DSA can efficiently handle larger batches, but it has a tradeoff between batch size and key size. Each key variant requires specifying a full-sized y value, while with Batch RSA the variants just required listing a small e value (and possibly not even that, if the exponents are the small primes). This will limit Batch DSA in most circumstances to similar batch sizes of on the order of tens of messages, otherwise the keys become unreasonably large.

Will Be: DEATH THREAT !!! to Follow... [Currently Is: Janet Reno is not an Indigo Girl...she's just ugly]
by TruthMonger 17 Dec '03

17 Dec '03

BillyG, No doubt world leaders and titans of industry have noticed the recent pause in the steady stream of death threats they receive daily, and are worried about my health, but you're the only one who sent a "Get Sicker" card... Nonetheless, I must put off catching up on my thinly veiled threats of ChainSaw Justice for a bit longer, in order to address an even more important concern, namely: "How the hell can fag girls be so cute and make such great music, when Janet Reno is so fucking butt-ugly and can only make bizarre, senseless noise?" Anyway, when you see the $on Little$ystems and Nut$crape crowd, tell them that the crazy Canuck who used to roam their hallways screaming, "Give your software away, you fucking idiots...you'll get filthy fucking rich!" now says, "Hi...and go fuck yourself." It's bad enough that Corporate A$$holes (TM) want me to call a game, "The MegaCorp Making Money Off Of Amateur Athlete$ Bowl", but when the fuckers start making Micro$not Ba$hing (TM) a corporate game where the players wear shirts with little animals where the pocket for your butts is supposed to be... Oil the fucking chainsaw, eh? In my last thinly veiled death threat to BadBillyC, I told him to tell Ms. Justice-Is-Not-Only-BLIND-It's-UGLY-Too that "MICRO$NOT is to INSLAW...as...ChainSaws are to ButterKnives." It had nothing to do with the Indigo Girls CD that woke me up this morning reminding me of Indio, Indians and INSLAW, and everything to do with Micro$not Ba$hing (TM) being every bit as sacred as having a butt on the crapper in the morning. When America can no longer count on the Little Guy to war against such basic human degradations as Life Under DOS, then we are doomed--individually and as a nation. Which brings me to another rambling point totally unconnected to my last chain of thought... I got to fiddling with the car radio last week and inadvertently drove past the bar, thus launching the "TRUTHMONGER WORLDWIDE CHAINSAW RETRIBUTION TOUR." Next thing I know, I'm in goddam British Columbia, making plans to set a few of the Royal Canadian Mace Police on fire, pop on down to Seattle try to get all of my Micro$not setup disks replaced (why are the setup disks all make out of rice paper?), and set the final plans for your virtual chainsaw deletion in motion within the ranks of the Circle of Eunuchs-Redmond Chapter. Next on The LIST (TM) was stopping in at Tacoma and Portland and ringing a few AP Bells to bring in the New Year with a pocketful of Ha$hCa$h, and then continuing my Bombed Blitzkrieg with a Budweiser Battle in the Bay, gathering the nerve for a frontal assault on Mayonaisse Mountain with A Nuclear Device To Be Named Later. To make a long story short, I woke up on Gomez's doorstep down in Berzerkeley, with a hangover, a dog, a huge fucking moose bone, the flu (or perhaps just a touch of The Potato Famine), and no fucking ChainSaw. What is even worse is that I don't seem to be in possession of even the few meager munitions I always have packed and ready for emergency situations, but I *do* have some rather vague memories of the last week that seem to match the newsclippings on my dash in regard to a trail of ugly little incidents coinciding with the times and dates on the gas receipts stapled to them. At first, I assumed that my inability to recall any details in regard to several of the incidents was a good sign, but a physical inventory of my vehicle seems to provide substance to the growing thought that the circumstantial evidence against me outweighs the loss of memory from the alcoholic delerium tremors. I seem to have my Opus SparCard II stuff from my pal at ASIX, which would confirm the vandalism in Seattle. I've got payout tickets from the casino in Lake County, which means the clipping about the flash bomb in Vallejo needs to be burned almost immediately. I was convinced that I would be able to maintain deniability for the torching by the Dumbarton bridge, until I realized that the Master Tapes for "My Way or the Highway" and "Please! Stop Me Before I Sing Again" must have been picked up from Arcal, in Redwood City. I have no fucking idea whose butt that is sticking out of the shallow grave in my sister's back yard, but since it has my name tatto'd on it, I assume I'll be on a backroad headed toward Canada very, very shortly. Anyway, I suppose it is proper serial killer etiquette to provide a legitimate death threat once my travel plans back to CanuckLand are in place, so I will try to drop one in the email on the return trip. Actually, you should probably invite all of the major players from the Corporate Micro$not Ba$hing Bowl (TM) by Ralphie, et al, to your place for a "Peace Conference" during my return trip, and then spend most of your time in the underground bunker playing cards with the Reptilian Nazi's, or something. To tell the truth, I'd just as soon snuff those whining fuckers on this trip, anyway, and Seattle's a nice town, so I wouldn't mind making an extra trip in the future, anyway. Shit! I just remembered that TeddyK's trial is in Sacramento, not Vallejo. I probably ought to do this shit when I'm sober. Hell, I might end up actually hitting my target, for a change, instead of just another in a series of random, innocent bystanders. I think this potato salad's starting to go bad...which container did I put the rincin in? Shit...I'd better go put some alcohol in my system, just in case...

Batch RSA for stego data
by Anonymous 17 Dec '03

17 Dec '03

Problem: Suppose there is a source of data which looks like random noise but which contains embedded messages. This may be a subliminal channel in a crypto protocol, steganographically embedded data, or even a simple message pool where you want to disguise what key each message is for. How do you scan and identify messages for you? Solution: Extract bits as appropraite, apply whatever selection rules are necessary to pull them out of the stego'd data or other source. Some fraction of what results is messages for you, the remainder is noise or messages for someone else, which will be indistinguishable. Method 1: For finding messages sent by someone you have communicated with previously. Use shared secret data to flag the message. Method 1A: each time you send a message, include (in the encrypted portion) a 64-bit random value which will be used to flag the next message to them. Prepend the encrypted message with the 64 bit random value from the previous message. Each person keeps a list of the next random value to be expected from each communicant. The extracted data can be easily scanned to see if it matches anything on the list. Method 1B: use shared secret data and a sequence number to calculate a hash which will be used to flag the next message sent. This can be used to calculate the flag value to be expected for the next message from each sender, which can be compared against each potential message. For both methods 1A and 1B, once the message is recognized a shared secret key is used to decrypt the remainder of the data past the flag portion. The shared secret key can be changed after each message using similar techniques to changing the flags. (Safety tip: don't make the shared secret key the same as the flag value.) Method 2: For finding messages sent by someone you have never communicated with previously. Method 2A: Sender encrypts a low-entropy flag message with receiver's public key, pads it so it looks like random noise, and puts that at the start of each message. Receiver decrypts the beginning of each message using his private key, looking to see if the results are low entropy. When such a message is detected the secret key for decrypting the remainder of the message can be embedded in the low-entropy portion. Method 2B: Like 2A, but use Fiat's "Batch RSA" to decrypt multiple messages in one batch. Recipient publishes his public key with multiple legal exponents (say, the first 16 primes). Sender encrypts his low-entropy message choosing one of the encryption exponents at random. He checks to see if the low bits of the encryption output match the index of the encryption exponent (e.g. if the 7th encryption exponent was chosen then the low order 4 bits should hold the value 7). He repeatedly encrypts with different random padding until he finds an encrypted form which properly encodes the exponent. Receiver batches messages together such that the low order 4 bits of each message in the batch are different, and applies the Batch RSA decryption to try decrypting each message. As before the receiver looks to see if the result is low entropy. For both 2A and 2B it may be possible to do the decryption using only one of the two RSA primes, if the encrypted data was smaller than that prime value. (This idea comes from Shamir.) Even if not, the Batch RSA algorithm can be applied separately for the two primes and then the results combined at the end for each message via the CRT, as is often done for RSA decryption.

Germany not so worried about Gestapo wiretaps now
by David Honig 17 Dec '03

There are several examples of sacrificing liberty for security in a G7 country in the article below. Also the justification of "getting in line with other countries" is used for allowing civilian SIGINT practices previously banned. Thursday January 8 11:32 AM EST Germany to Restore Surveillance BONN, Germany (Reuters) - German political leaders agreed Thursday to allow police to bug apartments of suspected criminals, restoring a crime-fighting tool banned since abuses by the secret police in the Nazi era. Leaders from Chancellor Helmut Kohl's center-right coalition and the opposition Social Democrats (SPD) said they had reached a deal allowing police to plant microphones in private homes of suspected criminals for the first time since 1945. Both houses of parliament are now expected to quickly pass the long-debated measure, which police have argued was needed to better fight organized crime and bring the country in line with other nations that allow electronic surveillance. Germany, which reacted to the Gestapo's abuses with some of the Western world's most extensive civil liberties laws, has long resisted any relaxation in constitutional protections that have kept police out of private homes. Interior Minister Manfred Kanther said the agreement would give police the necessary tool to fight organized crime. "This is a decisive step toward more effectively fighting crime," Kanther said. "We can now keep surveillance on suspected gangster apartments and we will be able to better fight money laundering." The opposition SPD, which controls the upper house of parliament, the Bundesrat, said it would support the measure after the government agreed to partial exemptions for some professional groups such as priests, attorneys and journalists. Police will be required to obtain advance court permission for any surveillance. Previously, police were only given rare exemptions to the constitutional law protecting the private home. They were allowed to use listening devices or electronic surveillance only with court permission if there was concrete evidence that a serious crime was about to take place. Now authorities will have the power to use eavesdropping methods far more extensively and will also for the first time be able to bug apartments after a crime has been committed to obtain evidence. Germany's post-war constitution barred police from electronic surveillance, telephone taps and intercepting mail. The bans on telephone taps and mail intercepts were relaxed in the 1970s amid a wave of left-wing guerrilla attacks. ------------------------------------------------------------ David Honig Orbit Technology honig(a)otc.net Intaanetto Jigyoubu "How do you know you are not being deceived?" ---A Compendium of Analytic TradeCraft Notes, Directorate of Intelligence, CIA
