    DNSSEC has its place, even for key distribution. But it does not provide a basis for trust because mere holdership of a DNS domain does not mean you are trustworthy.

    The big win for DNSSEC is to distribute security policy in a scalable fashion. See my CAA and ESRV Internet drafts.

    Imagine that you are visiting slashdot, wouldn't it be better to use SSL than en-clair if the site supports it? Wouldn't it be better to have encryption with a duff cert than no encryption at all? [*]

    DNSSEC allows a site to put a flag in its DNS to say 'always use SSL when visiting slashdot on http'. Now the server knows that if it is going to slashdot and it is not encrypted there is a man in the middle. Same for Twitter, Google etd.

    DNSSEC can also be used to ensure that the only certs trusted for a domain are ones authorized by the domain holder. This provides an independent trust path to CA issued X.509. If used in combination, security can be improved.

    [*] The catch is that showing the user the padlock icon for a duff cert is going to make them less secure. That is why I would like to see the browsers remove the padlock icon completely for DV certs. the only reason the padlock is required is to allow the user to check that SSL is in use. Since the user can't and won't do that reliably it is a poor control anyway. But it is in any case a control that should be enforced by the browser not the user and DNSSEC security policy allows that to happen.

    On key distribution, well sure, for typical Web services and for promiscuous security, DNSSEC validated keys are just fine. It is not going to be a money saver. It does not justify a padlock icon (neither does a DV cert). But it is perfectly adequate for most applications.

    Unfortunately it is likely that making use of DNSSEC for key distribution is going to be delayed for at least a year due to IETF politics. I blame the people behind the DANE proposal. They have been less than forthcoming about their real agenda from the start and have shown absolutely no willingness to accept any input from other parts of the IETF. The IETF is a consensus based organization but the test is IETF consensus, not working group consensus. If a clique wants to change the rules for handling PKIX certs they have to get an IETF consensus that this should be done.

    DANE could have easily been designed in a way that allowed security policy and key distribution to be completely separate. Unfortunately the ruling clique insists these be joined. The result is a spec that is in my opinion undeployable because the transition strategy for a scheme providing positive trust (key distribution) is by necessity very different to that required for a scheme that provides negative trust (key revocation, security policy, etc.).

    Oh I know what he is trying but he has no clue what the threat model is.

    The threat model in this case is a well funded state actor that might well be facing a full on revolution within the next 12 months. It does not matter how convergence might perform, there is not going to be time to deploy it before we need to reinforce the CA system. [Yes I work for a CA]

    I think it most likely we will be seeing the Arab Spring spreading to Syria with the fall of Gaddafi. We are certainly going to be seeing a major ratcheting up of repressive measures in Syria and Iran. Iran knows that if Syria falls their regime will be the next to come under pressure. In many ways the Iranian regime is less stable than some that have already fallen. There are multiple power centers in the system. One of the ways the system can collapse is the Polish model, the people of Poland didn't have a revolution, they just voted the Communist party out of existence. If the Iranian regime ever allows a fair vote the same wil happen there.

    Anyone think that we will have DNSSEC deployed on a widespread scale in the next 12 months? I don't and I am one of the biggest supporters of DNSSEC in the industry. DNSSEC is going to be the biggest new commercial opportunity for CAs since EV. Running DNSSEC is not trivial, running it badly has bad consequences, the cost of outsourced management of DNSSEC is going to be much less than a DNS training course ($1000/day plus travel) but rather more than a DV SSL certificate ($6 for the cheapest).

    The other issue I see with Convergence is that it falls into the category of 'security schemes that works if we can trust everyone in a peer to peer network'.

    Wikipedia manages a fair degree of accuracy, but does anyone think that they really get up to 99% accurate? Until this year the CA system had had three major breaches, all of which were trapped and closed really quickly plus about the same number of probes by security researchers kicking the tires. Until the Diginotar incident anyone who had revocation checking in place was 100% safe as far as we are aware, not a bad record really.

    There is a population of about 1 million certs out there, even 200 would mean 99.95% accuracy.

    Running a CA is really boring work. Not something I would actually do personally. To check someone's business credentials etc takes some time and effort. It is definitely the sort of thing that you want a completer-finisher type to be doing. Definitely not someone like me and for 95% of slashdot readers, probably not someone like you either.

    The weak point in the SSL system is not the validation of certs by CAs, they are (in order) (1) the fact that SSL is optional (2) the fact that the user is left to check for use of SSL (3) the fact that low assurance certificates that have a minimal degree of validation result in the padlock display.

    The weak point being exploited by Iran is the braindead fact that the Web requires users to provide their passwords to the Web site every time they log in. I proposed a mechanism in 1993 that does not require a CA at all and avoids that. Had RSA been unencumbered I would have adopted an approach similar to EKE that was stronger than DIGEST but again did not require a cert.

    Certs are designed to allow users to decide who they can share their credit card numbers with. That is a LOW degree of risk because the transaction is insured. Certs are not intended to tell people it is safe to share their password with a site because it is NEVER safe to do that.

    The typical recording contract of that era was expressly designed to avoid being categorized as 'work for hire' as it would mean a shorter copyright term.

    So really no different from Communists, Fascists, Moonies, and other cultists.

    And the fact that the Tea Partiers talk about freedom all the time means precisely nothing. Karl Marx talked about freedom. So did Lenion, Stalin, Hitler, Mao and pretty much every other demagogue. And before he became Chancellor, most Germans regarded Hitler with pretty much the same disdain as Glenn Beck is considered.

    When people talk about 'second amendment solutions' or the 'ammo box', what they are talking about is the murder of their political opponents. I don't draw comparisons with fascists and Stalinists lightly, but talking about murder of opponents crosses that line completely.

    Whether or not Loughner's action in Arizona was a consequence of Palin and Beck's rhetoric can never be proved or disproved. But what is beyond dispute is that 1) that type of rhetoric can lead people to murder, 2) there is ample evidence that Palin in particular intended to use that rhetoric in order to intimidate her opponents, 3) no member of the Republican party leadership had the courage or the principles to condemn the rhetoric when it was being used.

    So no, I don't think that the consequence of a tea party government would be less regulation or government interference. The people simply don't have the knowledge or experience to form a coherent policy, let alone implement one. What would result would be an increase in regulations that protect the interests of narrow cliques that can manipulate the party and a decrease in regulation that serves the public interest.

    There was a substantial information warfare campaign designed to persuade the Iraqi generals to defect in return for certain guarantees. A significant number did so and there was considerably less fighting than expected.

    That strategy worked in Iraq because Saddam was in a much weaker situation politically. The generals were willing to defect because they were not particularly eager to fight for Saddam. A regime change in which they maintained their position and status would suit them rather well.

    It is much less likely that the same strategy would work a second time, not least because the Iranians are prepared for it but more importantly because the US went on to break each and every one of the guarantees that they had given to the Iraqi generals. Instead of allowing them to keep their positions, the US abolished the Iraqi army and threw most of the defecting generals in jail. Instead of effecting a quick, relatively bloodless coup, the US created a civil war which claimed the lives of between half a million and a million Iraqis.

It is unlikely that the religious leadership would want to allow him to complete a nuclear bomb: it would put him above them. If Iran really wanted a nuclear weapon they would have one by now, they have vastly more resources than were available to the Manhattan project in the 40s. Another possibility is that Iran does already have a nuclear bomb but is unable to declare it since that would lead to an immediate attack etc.

The press will repeat any nonsense that is said to them by someone who is convinced they are right.

    If the target was indeed the Iranian centrifuges or the Iranian power plant then the only way that it could have possibly been expected to work would be with very deep knowledge of the design and deployment of a top secret Iranian facility. There are only two ways that knowledge could be available to the attacker - if they designed the plant or if they had a source with access.

    Looking at the likely result of this attack I cannot possibly see how anyone would wish to let the Iranians know about the intelligence source for the sake of some minor inconvenience to the Iranian program.

    A much more likely explanation in my view is the idea that the Russians wrote Stuxnet to damage the nuclear plant they designed and thus require Iran to buy additional services from Russia to repair the damage and to accept the reprocessing proposal (which they did). Such shakedown tactics were common during the Soviet era.
