What's Now State of the Art in Encryption Technology?
One thing about encryption: the easier it is to do, the more people there will be using it. For the non-tech user, encrypting messages on a day-to-day should be no more complex than 3 steps.
JPMH asks:"First journalists and now even relatively clued-up politicians in the UK are talking about making it an offence to use strong encryption in email and web-pages. An obvious counter is that this won't work, because the messages can easily be hidden using Steganography (Slashdot Jan 2, May 8). But that assumes that the steganography itself is good enough not to be detected. Is this true? How good is the state of the art?
To be undetectable, the properties of the 'message' bits you are putting in must be statistically indistinguishable from the 'image' bits you are overwriting. According to a paper by Neils Provos and Peter Honeyman of U. Michigan (highlighted today in the Register) the simplest common programs, such as JSteg and JPHide, fail this test badly and are easily detected. But they failed to nail any confirmed steganographic content in 2 million images on EBay.
Other programs (eg Provos's Outguess 0.2) are more sophisticated at hiding the messages (and other media eg MP3s give a bigger haystack to hide them in); but on the other hand, more sophisticated statistical models of images (eg Slashdot 16 Aug) may be better at making the 'hidden' content stand out.
So, can messages reliably be hidden? Or will people trying to hide their messages in a reliable manner get caught?"
Hate to get all Gammar Nazi on your ass, but bin Laden is bin Laden, not Bin Laden (unless starting a sentence).
In an interesting display of synchronicity, Slashdot authors still don't read Slashdot until after they have made their posts.

To begin with, it is arguably good that this happened. The West is wide open to suicidal terrorist attacks, and if there were ever such an attack with a nuclear bomb, things would be a lot worse. Many people have been warning about this for some time. Now at least some preventative measures will be taken, and the risks will be reduced. Nuclear bombs are actually trivial to make if you have weapons-grade uranium (still a large "if"); so the risk is significant. Bin Laden has been trying to arm himself with nukes for years.
If we want to understand what happened, we should ask what the terrorists' motivations were for attacking. The terrorists say that they hate America for its actions against Muslims in Palestine and Iraq, and Islam teaches that Muslims should aid other Muslims. So, what have been America's actions?
The Palestinians have been brutalized by the Israelis. Consider that the UN High Commissioner for Human Rights stated that rarely had a people been in so obvious need of international protection--last November, after seeing children whose eyes had been blown out by Israeli bullets and watching 40000 Palestinians kept under curfew so that 235 Israelis could go about their business (in Hebron). The Palestinians have repeatedly asked for international observers, but always had this blocked by Israel and America. Palestinians have long been tortured in Israel (this is government- sanctioned). The recent UN report headed by American ex-senator Mitchell made various recommendations, which were entirely accepted by the Palestinian Authority and rejected by Israel. Basically all other independent reports conclude that the Palestinians are treated abominably, including severe economic deprivations. (This is not to say that Israel does not have valid security concerns or grievances against Palestinians.)
Israel can only act this way because of American support. Indeed, America supplies advanced arms, gives Israel's six million citizens billions each year, and is often virtually the sole supporter of Israel in UN discussions-- such as discussions about Israel's violations of UN resolutions. So America is an accomplice. Even the British Foreign Secretary has now acknowledged that "One of the factors which helps breed terrorism is the anger which many people in [the Middle East] feel at events over the years in Palestine."
Some people have claimed that Bill Clinton tried to achieve peace, and so America should not be held to blame. But Israel only exists because of American support. And America, under Clinton, did not use this power. Under Bush Sr., things were different: Bush Sr. threatened to withhold $10 billion in loans (strictly, loan guarantees), if Israel remained brutal. This worked: the Oslo peace process. The process could have remained on track if America had decided to force Israel to keep it signed word.
In Iraq, American-dictated sanctions ban anything that could conceivably be used for the military. For example, pencils contain carbon and carbon is often used in nuclear reactors; so pencils were banned. The sanctions are horrid. The sanctions regime is always supervised by a non-American (for political/PR reasons), and the supervisors have always quit in disgust after about a year, which says a lot. Iraq's infrastructure and economy are being crushed, at enormous cost. For example, according to UN estimates, the sanctions have resulted in the death of half a million children under five. (None of his is to suggest that Saddam is undeserving of a very tight leash, nor that this could be applied without the people suffering significantly.)
What does bin Laden say? Even if he was not directly involved in the attacks (which seems unlikely), he is a leading member of the terrorist network; so his words very probably count for something. And in the past he seems to have spoken more or less honestly about his intentions. In a 1999 interview, he said he wanted to instigate "... jihad against the Jews and the Americans" and, citing the sanctions against Iraq, he added, "Our enemy is the crusader alliance led by America, Britain, and Israel." And in 1998, he and four others signed the World Islamic Front Statement, which advocates killing Americans for three reasons: America's support of Israel, America's killing of over a million Iraqis (a figure consistent with UN estimates), and America's stationing its armed forces in the Arabian peninsula. Regarding the third reason, the main complaint seems to be that America is using the peninsula as a base for aggression against Iraq--i.e. the second and third reasons are closely related--though it is also true that Muslims consider the peninsula holy and many do not want non-Muslims permanently residing there.
The leader of the Taliban has also said why America was attacked: because America's cruel foreign policies perpetrated atrocities in Muslim countries.
So, this is not an attack on democracy and freedom per se, as George Bush claims. Nor is it a culture-based "clash of civilizations", as some commentators have tried to claim (alluding to a 1993 essay by Samuel Huntington). Nor is it an attack based on spiteful envy of American might, as some others have claimed. This is an attack by Muslim fanatics on non-Muslims who have been brutalizing Muslims. Many Muslims around the world have stated that they share the hatred felt by the terrorists, for the reasons given above, even if they strongly condemn the terrorist attacks.
(Some people point out that Muslims sometimes also brutalize other Muslims. This is true. Any group of people will have internal conflicts, occasionally very severe--as here--but still often pull together when attacked from outside. This is generally true of families, for example. It is also true of Americans--as this month has shown. It is something to be proud of.)
The terrorist attacks appear to have opened an enormous well-spring of Muslim anti-American feelings. Muslim demonstrations against America have been widely reported--even though demonstrators, when interviewed, have said they are against the terrorist attacks. In Indonesia (85% Muslim), gangs of extremists have been going into hotels searching for Americans.
Many Americans seem greatly confused by widespread Muslim hatred. To them, the claim that America desires to control the world is ludicrous. Especially since the end of the Cold War, America has tended to interfere in the affairs of other countries only under extreme circumstances. The Balkans is the prime example--where Europe fretted fecklessly while tens of thousands were killed or raped. Almost all Americans simply want the world to develop in peace and prosperity--and, incredibly, they ask for nothing in return despite being the world's greatest guarantor of this. But, for Muslims, it does not look that way. America helps a state with which it is friendly--Israel--and tries to squash a state that is very threatening and sinister--Iraq--and it ends up looking imperialistic.
Regarding the terrorists' motivations, it is interesting to compare the reports given by American and British mass media. I've spent many hours watching CNN and BBC World, and looked at several major newspapers in both America and Britain. Broadly, the American media has portrayed the terrorists as crazies who are against economic modernization and Western culture. Broadly, the British media tends to say that the terrorists are at least rational and that America inspired the hatred that they feel by its support of Israel. (Of course British media still condemn the attacks.)
Britain has not really supported America's actions in Israel/Palestine. In fact, the previous Foreign Secretary (Robin Cook) was fired in part because he was too blatant in his support for Palestinians. But Britain has--almost alone (to my knowledge)--both aided and supported America's actions against Iraq. The British media thus cites the main Muslim grievance in which Britain is blameless and largely ignores the other. The American media ignores both. Even considering some criticism is unacceptable, it seems.
The media made a lot of sacrifices when the terrorists struck. Hundreds of millions of dollars in advertising were lost as commercials were pulled from TV to make way for more news. And it was clear that many commentators very much had their hearts in their work. I still believe, however, that the media has done a disservice to people by failing to present the terrorists' true motivations--even if they disagreed with them.
The big question now is what can/will be done to make things safer. Despite all the hype, suicide bombers are rare. But, there are about a billion Muslims in the world; so even if only one in a 100000 becomes a bomber, that's 10000 overall. More people will now want to become bombers, though, for three reasons: the success of the attacks on America, the hero status often accorded suicide bombers (in Palestine as well), and the continuing despair that many Muslims feel about the plight of Palestinians and Iraqis.
One obvious way to increase Western safety is to inspire less hatred and give Muslims some hope for a better future. It was the crushing of hope by Israel that led to the recent spate of suicide bombers there. America is plainly well aware of this. Thus, although in the first week Israeli PM Sharon was stating that he still wanted to conquer the Palestinians, on September 18th he did an about-face--obviously under great American pressure. Real peace needs to be brought to Palestine. Arafat wants it, but with land; Sharon only wants victory, but might give in; and there are extremists in both Palestine and Israel who will try hard to derail peace. So lasting peace will hard to get, but maybe ... maybe. As for Iraq actions,
this is under American control; so sanctions should ease rapidly ... maybe.
In addition to these diplomatic efforts, there is going to be a military effort. The one purely-American purely-military option that I've seen that might potentially do something is to nuke Afghanistan. This would be politically very difficult. It would also inspire so much hatred in the Muslim world that for each terrorist killed, several more would be spawned. So I don't believe that America will do this. (On the other hand, Russia wants to help generally. And Russia has an enormous grudge against Afghanistan for beating it the 1980s and even more now for Afghan support of the Chechnya rebels. Russian TV has recently been reporting that Russia plans to nuke Afghanistan. I've no idea what to make of this, but suspect, or hope, that nothing will actually happen.)
Some people have suggested heavy (non-nuclear) bombing of Afghanistan, to force the Taliban into expelling the terrorists. There are no substantial military or political targets, however, and the Afghan economy is now virtually nonexistent, thanks to international sanctions and an extended drought. The UN estimates that by November (after snow starts falling), five million Afghans will be dependent on food aid--out of a population of 20 million. So if the objective is to crush the economy, simply stopping food aid would do more than any bombs. In fact, this is now happening, as relief agencies flee the country out of fear of military action. Actual bombing seems pointless, then, except perhaps as PR. Will a famine (induced by bombing or threat thereof) compel the Taliban into expelling the terrorists? This is dubious: the Taliban apparently shelter the terrorists because of an Islamic custom--if someone seeks refuge in your tribe, you have to protect him, regardless of the cost (the Taliban actually have little interest in the world outside Afghanistan.) Inducing a famine is also risky: if a million die, it will fuel more Muslim hatred. Would it be moral? You decide.
There has been much discussion about sending special forces into Afghanistan. This requires intelligence on where the terrorists are hiding. Indeed, by now many of the terrorists will be dispersed among the population: good intelligence from the ground is essential for successful special-forces action against them. America apparently does not have this intelligence itself. It might try to bludgeon the ruling Taliban into supplying such intelligence, but it is uncertain, at best, that the Taliban should be relied upon to act in good faith, if they acted.
The Taliban, however, are very close with Pakistan (see below). So if America were to work with Pakistan for intelligence, it might get somewhere. The president of Pakistan has pledged full support, but this might mean little. The support has to come from the people on the ground, and there have been many demonstrations in Pakistan against helping America. I know of three reasons for these demonstrations. First, Pakistani's are Muslims (95%) and they blame America for what is happening to Muslims in Palestine and Iraq. Second, they don't like being bullied by Westerners generally. The third reason is more involved; briefly, it's as follows.
The current border between Pakistan and Afghanistan is actually just a line of control (the Durand line), from a treaty that expired about five years ago. It was never clear what was to happen when the treaty expired: likely Pashtoonistan--an area overlapping both Pakistan and Afghanistan--was to be made into a state. The Pashtoon people make up nearly half of all Afghans, and they control Afghanistan; so likely Pashtoonistan and Afghanistan would become one. The effect would thus be to have Pakistan cede territory to Afghanistan. (A rough analogy might be how Britain ceded Hong Kong to China after the expiration of a 100-year treaty/lease. The Durand treaty was drawn up in the 1890s, when Pakistan was still a part of India.)
Pakistanis, especially in the military, are very reluctant to cede a large part of their country to Afghanistan. That's why Pakistan created the Taliban. The Taliban were given both military and religious training in Pakistan. They also got lots of arms and money from Pakistan, which is why they were able to conquer (most of) Afghanistan. They were largely controlled by Pakistan, though. And under Pakistani control, they did not force the issue of Pashtoonistan. (Lately, Pakistani control has weakened.)
America has addressed this by telling Pakistan that unless it helps, America might rid Pakistan of its nuclear installations and support India militarily: in effect, saying that Pakistan would be liable to lose a majority of its territory (to India) rather than a minority (to Afghanistan). The president of Pakistan has made a televised speech warning people "bad results could put in danger our territorial integrity." This should help to focus the minds of those in the military, especially since Pakistan has a military government. Yet, it has had little effect on the populace, who are more motivated by sympathy for fellow Muslims. Will the low-ranking Pakistani soldiers on the ground go along and will they get enough intelligence from Afghanistan with little help from the populace?
My guess is that Pakistan will pretend to go along, and perhaps even help find a way to get bin Laden--which is good for PR, but not for really eradicating the terrorist network. Maybe America will eventually help to formalize Pakistan's borders, which would facilitate greater Pakistani support. I have not, however, seen this discussed publicly.
There also seems to be a common view that the Taliban should be forcibly removed from government. The likely approach here will be to strongly support the anti-Taliban forces that currently control under 10% of (northern) Afghanistan. (This support might include bombing, but only on a small scale.) Starved of external military support, the Taliban should crumble quickly. One complicating factor is that any large military campaign in the Afghan winter is very difficult, and winter arrives in about October. What is also important is to avoid making it seem as if this is American imperialism, which would unite the populace and draw wide Muslim anger.
The military action, whatever form it takes, will make it difficult for the terrorists to train or actively maintain their network in Afghanistan. Capturing many terrorists, though, seems unrealistic. The threatened mass bombing has made this even more difficult, since many Afghans have fled population centers for safety: there seems no good way to find a terrorist, who looks and acts ordinary, in their midst. If the Taliban are removed from government, though, perhaps more Afghans would then supply intelligence.
There is also a lot of detective work underway. Within America, and some other countries, this seems to be on track for some success, for identifying terrorists and also for choking their financing. There appear to be a large number of suicidal Islamic terrorists in the network that attacked America, though. Estimates are rough, but there could be a thousand who have deeply infiltrated the West. As an example, one of the highjackers had apparently spent several years in Germany getting a technical degree. The network has supposedly spread to roughly 40 countries, which will hinder tracing it. Also, there is no real command structure: there is only a network (like the Internet is a network) with some people more influential than others; so even if someone like bin Laden is caught, the network would hardly be eradicated (a bit like taking out a few major nodes of the Internet would do little). Tracing the network is thus going to take a long effort, but should succeed.
Diplomatic, military, and detective efforts could also be supplemented with religious efforts, though I have not seen this discussed much. Bin Laden has claimed that he is instigating a jihad. Jihads were fought many centuries ago, against the crusaders. The jihad concept was then largely forgotten. When the Soviets invaded Afghanistan in 1979, the CIA looked for ways to help motivate the Afghans to fight (this was during the cold war; so the CIA was arguably justified). One of they ways the CIA came up with was the revival of the long-abandoned notion of jihad. It worked (although the defining event in the Afghan-Soviet war was probably America's decision to supply the Afghans with shoulder-launched Stinger anti-aircraft missiles).
The Koran, though, teaches that a jihad should not harm women and children. And bin Laden himself said (in 1999) that "God ... has prohibited the killing
of women and children unless the women are active fighters." Fighting the
Soviet army fits with this. Crashing planes into the World Trade Center does
not. Of course, religious fanatics can twist anything ("America is a
democracy; so the people are directly responsible for what their government
does; so the women killed in the World Trade Center were active fighters."--
maybe?). But I believe that it should be possible to use the Koran, and
perhaps even Muslim clerics, to motivate Afghans against the terrorists.
What are the overall conclusions? In the short term, there is small, but real, risk of another terrorist assault, against America or perhaps Britain (or Israel). In the medium term, the terrorist network will be attacked and largely eradicated, and America's resolve will make all countries very hesitant about sponsoring other terrorist networks. Additionally, there will be widespread, permanent, increases in security measures. Individual terrorist incidents, however, do not require a sophisticated network or large resources (remember Oklahoma City). It is not realistic to expect to be able to prevent them all. In the long term, then, we also need to lessen the causes of Muslim grievances, even if it means facing up to our past mistakes.
