Australian Attorney General Wants To Make It A Criminal Offense To Not Turn Over Private Encryption Keys

from the a-disaster-waiting-to-happen dept

The Attorney-General's department in Australia is apparently pushing for new laws down under that would force anyone who's asked to hand over their private encryption keys -- and that covers both end users and service providers. Buried in the middle of a submission concerning revising Australia's wiretapping laws, the AG's office notes:
The Department is also advised that sophisticated criminals and terrorists are exploiting encryption and related counter-interception techniques to frustrate law enforcement and security investigations, either by taking advantage of default-encrypted communications services or by adopting advanced encryption solutions.

The Department’s current view is that law enforcement, anti-corruption and national security agencies should be permitted to apply to an independent issuing authority for a warrant authorising the agency to issue ‘intelligibility assistance notices’ to service providers or other persons. The issuing authority should be permitted to impose conditions or restrictions on the scope of this authority.

[....]

Under this approach, the person receiving a notice would be required to provide ‘information or assistance’ to place information obtained under the warrant into an intelligible form. The person would not be required to hand over copies of the communication in an intelligible form, and, a notice would not compel a person to do something which they are not reasonably capable of doing. Failure to comply with a notice would constitute a criminal offence, consistent with the Crimes Act.

The above approach is consistent with the approach taken by the United Kingdom, which permits officials of law enforcement and national security agencies to, where authorised under a warrant, issue a notice requiring a person to provide assistance in connection with accessing encrypted communications. Similarly, South African law permits agencies to apply to a judicial officer for a direction requiring a person to provide information to the agency to enable the agency to decrypt lawfully intercepted communications.
The Orwellian nature of "intelligibility assistance notices" is fairly striking. Basically, this says if you don't make encrypted communication "intelligible" upon request, you would have violated criminal law. It's kind of funny how it claims this doesn't require anyone to hand over communication in an intelligible form... because it just asks for the encrypted content and the key to decrypt them. Which, you know, is basically the same damn thing.

Meanwhile, at the same time as part of the same discussion over wiretapping laws, there's an effort under way in Australia to force service providers into a big data retention scheme, forcing them to hold onto all sorts of data for law enforcement purposes. Incredibly, Australian officials seem to be using the NSA/Snowden leaks as the impetus for this.
Intelligence agency ASIO is using the Snowden leaks to bolster its case for laws forcing Australian telecommunications companies to store certain types of customers' internet and telephone data for a period of what some law enforcement agencies would like to be two years.
ASIO also, like the AG's office, seems quite concerned about you damn kids and all your encrypting:
"Since the Snowden leaks, public reporting suggests the level of encryption on the internet has increased substantially," ASIO said.

"In direct response to these leaks, the technology industry is driving the development of new internet standards with the goal of having all web activity encrypted, which will make the challenges of traditional telecommunications interception for necessary national security purposes far more complex."
So, even if everything's getting encrypted, certain law enforcement interests seem hell-bent on having everything collected and easy (forced) availability of private keys. If you happen to live in Australia, you might want to speak up about what's about to happen to what you thought were your private communications and browsing activity.

    Ephemeral keys

    That's the reason for ephemeral key schemes (DHE, ECDHE, OTR): once the communication is finished, the key is discarded and nobody can decrypt the communication anymore. Not even the sender or the receiver.

    It's no surprise that there has been a stronger focus on increasing the use of ephemeral key schemes.

    Re: Ephemeral keys

    The problem with this idea is often one needs to reread the message/document at a later date. This need could lead to a situation where one reencrypts the plain text using a permanent key.

    I often wonder if most people would be better with a very strong log on password and no encryption. Some would need to encrypt selected files such as lawyer-client communications. Given the technical competence of most police departments, a strong password would stop them could. It would never occur to them to use a Linux live CD/DVD to view the files.

    The people's current view is that citizens should be permitted to apply to an independent issuing authority for a warrant authorising the citizen to issue 'intelligence assistance notices' to political representatives or other government officials. The issuing authority should be permitted to impose conditions or restrictions on the scope of this authority.

    Under this approach, the person receiving a notice would be required to provide ‘evidence of their intelligence’ to explain the incredibly bad ideas they have proposed in an intelligible form.

    What's driving the current push towards increased encryption is the knowledge that certain governments are more than willing to compromise their citizen's expectations of privacy and trust, NOT the tech sector. And as for making your job more complex than tapping cables and listening to unencrypted conversations? Too. Fucking. Bad.

    Just implement a data decryption protocol that allows you to enter a "fake" passsword that trashes the data and/or shows irrelevant info such as public domain content. If you do the latter, they may be tricked into thinking that it was the only thing being protected.

    Then, invoke the 5th when it comes to whether that is the legit content, no matter if it is or isn't.

    Re: Re: Ephemeral keys

    That's for data "at rest". The bad idea mentioned in this article is about communications, not data at rest.

    There is no need to reread communications. Once it arrives at its destination, its key can be discarded without issue. By their nature, communications are ephemeral, which is why ephemeral keys work well.

    Yes, once at the destination, you should re-encrypt whatever you received with a permanent key, if you want to keep a copy. Or the sender could have already encrypted it for you with a permanent key, while still protecting it with an outer ephemeral key. There are other bad laws that force you to reveal your permanent key, but again this is not what this article is about; and you might have the option of not saving the message, thus avoiding these laws.

    Not the same damn thing at all

    It's kind of funny how it claims this doesn't require anyone to hand over communication in an intelligible form... because it just asks for the encrypted content and the key to decrypt them. Which, you know, is basically the same damn thing.

    It's not the same damn thing at all. It's worse.

    There's a fundamental difference between handing over decrypted content, and handing over encrypted content plus the key. When somebody hands over their key, it allows you to read not only the encrypted content you asked for but also any other encrypted communications you may have intercepted.

    This is most notable because the policy is specifically stated to apply to service providers. As an example, a single investigation of a single Facebook user would allow the investigators to grab a copy of Facebook's private SSL certificate. Once they had that certificate, the investigators could read any Facebook traffic sent to or from any user over HTTPS.

    This is carefully phrased to the extent that I suspect it's by design. If this were passed into law, it would fundamentally compromise not only SSL, but pretty much all current asymmetric-key cryptography.

    be afraid, very afraid

    I live in Oz and I do have to say that unfortunately speaking up is unlikely to have much effect on our new AG who is perceived as a particularly nasty and vindictive man.

    Since coming into office he has so far:

    Authorised a raid on a Lawyers office in clear breach of attorney/client priviledge that was solely designed to intimidate a witness (highly ranked Intelligence officer, whistleblower) who was about to appear in the Hague to testify about illegal spying by our Gov during sensitive negotiations with East Timor. They confiscated the evidence and the passport of the wintess under "National Security" guise. Sound familiar? In reality, the evidence would have seriously embarrassed a number of the AG's colleagues who were in power at the time

    Indicated he is looking to make ISP's liable for the actions of their users. Was not to happy with the Supreme Court decision re. iinet (search Techdirt if you want more info) so wants to change laws to suit.

    Wants to repeal racial vilification laws to appease Rupert Murdoch's media interests in the name of free speech..... then in the same breath, as our Arts Minister decides that a bunch of artists who exercised their own free speech rights by declining sponsorship for a festival from a company employed by our Gov in the handling of refugees (very controversial topic here) should be forced to accept sponsorship.

    This is despite the fact that there are laws in place that quite explicitly state that Arts Minster is not permitted to attempt to interfere with the independent body that handles Arts Funding. He has already stated he is just going to ignore the law and force the body to comply.

    This is our AG. If there are laws in place that may inconvenience his party or their rich backers, he just either ignores them or wants to force through changes without following any kind of due process. And this is the man responsible for enforcing our own laws.

    Make your own judgement.

    Brain-dead like PKCS#1? PGP / GPG? SSL?

    This law would affect anything that uses asymmetric keys. If Alice encrypts her message with your public key, and you're required to hand over her encrypted message plus the means of decrypting it, then they're asking for your private key. Giving them your private key is worse than giving them the decrypted message.

    I suspect that what you're trying to say is that most modern crypto systems use key exchange algorithms to generate transient per-session or per-message keys. This is true. But by design, those transient keys are never saved. Even writing those keys to disc means that you're doing it wrong.

    As I said in my original post, the AG's submission was made using very careful phrasing. I doubt anyone in the AG's office wants a service provider to hand over, say, a raw dump of encrypted TCP/IP packets plus the generated key from a Diffie-Hellman algorithm. What it does sound like, at least to me, is that they're trying to get a legal way to harvest private keys.

    George is actually a very well known and brilliant lawyer though he has negligible experience with criminal law since his practice was entirely devoted to civil. Which realistically doesn't mean squat as the AG since he has a multitude of minions working for the Department who really do all the work and he just spews forth their IDIOTIC recommendations.

    As for this recommendation, it's idiotic, bypasses all procedural fairness (especially since it's NOT using a court to issue warrants but an external 'independent' -HA FUCKING HA - issuing authority) and is unworkable with so many chilling effects.

    Senator Brandis may be a "brilliant" lawyer, but in my experience, lawyers are technological imbeciles. I have already spoken to my member about the incompetency of the current Attorney General in relation to technological matters. Interestingly, though he said nothing against the man, which shows my member's good sense, one did get the picture that the Attorney General may not have been his most favourite fellow parliamentarian (they are of the same political party). He did say something similar about the minions.

    One has to remember that the vast majority of lawyers think that the only solution to any problem is making a new law. It's the old adage about only having a hammer and everything looking like a nail.

    Lastly, Senator Brandis being a QC essentially means that you do not want to have anything to do with him. The general rule of thumb for any business that provides services of any kind is to avoid doing any business with lawyers, especially barristers and QC, as you won't get paid for your efforts or if you do, it will have cost you many times more the amount paid.

    Brandis is basically a technology noob, I never said differently, and if you want a Senator that actually has anything like a CLUE in the current Senate (and hopefully in next depending on how WA goes) then Scott Ludlum is the ONLY bet at the moment.

    Sadly the above policy is NOT the only idiotic submission that has been put forth due to the actual Senate inquiry into the TIA (Telecommunications Interception & Access Act) put forth by the Greens with an emphasis on internet surveillance. The other stupidities are:

    * data retention provisions (that were rejected by parliament already) to be part of a new TIA .WTF!!!!!!!!

    * The NT Police (as if they don't have enough problems already) called for EVERYONE'S browsing history to be logged so it can be used in investigations for them (or anyone)

    * The AFP and ASIO (+ other acronyms) have asked for hugely expanded data retention and surveillance powers that bypass standard procedural fairness doctrines.

    * though ironically all areas of government(s) all state that privacy is IMPORTANT (Though that could be because the new Aust Privacy principles came into effect on 12th March) but only when it doesn't suit there own mandates.

    Actually the full list of submissions is fascinating reading as to whom is actually wanting what etc etc. http://www.aph.gov.au/Parliamentary_Business/Committees/Senate/Legal_and_Constitutional_Affairs/Comp rehensive_revision_of_TIA_Act/Submissions

    Been there, gone through that ambiguous bullshit from both sides of evidence collection under that legislation. Also the subpoena/warrant is authorised by a Court (Local/Magistrate or District normally) and NOT by some other non trier of facts body set up for that express purpose (ie:tribunal) as the AG want in this matter.

    This wanker is both Attorney General & Minister for the Arts, the proposal last week on copyright reeked of conflict of interest.

    > If you're setting up a website that uses HTTPS, do you generate (and get signed) multiple private/public keypairs for its certificate?

    If you are using DHE or ECDHE (and you should), that's exactly what you are doing: your certificate is used only to sign a new public/private keypair for each connection.

    > If you use a VPN, do you use that VPN for only one kind of traffic with a single recipient?

    If it's an IPSEC VPN, the IKEv2 negotiation generates a new public/private keypair every time you open the VPN connection. It's used for all the traffic within the connection, but it's forgotten as soon as the connection ends.

    > Do you create a new bitcoin wallet for every transaction?

    Christ, do you even know how a bitcoin wallet works? Hint: a bitcoin wallet is not a public/private keypair. It's an ever growing set of public/private keypairs. The reference implementation creates a new keypair for the "change" on every transaction.

    That only leaves GPG, where you actually can create a separate subkey for each individual, and keep the master key offline, but it's too much work for most people.

    You want my password to decrypt? No problem! It's "GovSuxDballz69". What's that you say, it's not working? You must not be typing it in correctly. Just keep on trying and if it still doesn't work... well I'm no tech expert, but my guess would be you screwed something up. No, that really is my password. Honest! ;-)

    Re: Re:

    TrueCrypt is great and I've been using it since v4, primarily for security against theft. My OS drive is fully encrypted, as well as my 12 TB data center and backup drives as well.

    The key is to backup those headers and all your important data from time to time. Otherwise you run the risk of losing it all permanently when you do something dumb.

    Oh and always use a password you'll remember even if you don't use it for 6+ months, yet isn't easily guessed either. Learned that the hard way lol.

    Using the Snowden leaks to "bolster its case" is really odd. If anything you'd think doing so would weaken their case.

    Re: Re: Re: Not the same damn thing at all

    For PGP and similar protocols you might be in compliance if you handed over the ephemeral symmetric key(s) for each of the messages concerned. If you have the encrypted message, you can still use your private key to decrypt the session key, and give them that.

    Of course, that means you know which messages they're reading, so they would probably change the rules pretty promptly after they figure that out.

    Re: Re: Ephemeral keys

    Nobody should listen to this, it is completely naive and very stupid to think that the law would not be able to access a system protected by only a logon password.
    Encryption is the way forward and if you have anything you need to protect, regardless of the content you should always use a strong encryption. Why do you think TrueCrypt has ceased development? It's likely because it is reliable in most cases.
