That's not my understanding of how the Apple store works. Apple does
modify the app before distribution (they have to apply their DRM for
example), and so the user cannot verify against the original signing
key. The developer signing key is for purposes of testimony to Apple,
not to the later user. Also, it arguably violates the App Store
distribution agreement for a developer to distribute her source or
binary from any other place -- the App Store distribution agreement is
designed to be an exclusive one. (Obviously a lot of people do
distribute their iOS app source from their own sites, but this is what
the apparently unenforced agreement said last I looked.)

I could be wrong about this, as I haven't gone over the details lately,
but I'm pretty sure that's right.

See for example
:
 

"A server error caused the FairPlay DRM encoding to fail, which resulted
in users receiving corrupted binaries when applying any recent updates
via the iOS App Store or the Mac App Store. These corrupt binaries would
crash on launch, failing to authenticate properly as a legitimate
download. Arment had identified as many as 120 apps that had been
affected by the issue as of Thursday."

Signing isn't sufficient without some means of invalidation under the
developer's control. Even putting aside users who are slow to update,
select users can be served older versions of apps with known
vulnerabilities intact.

I don't know how the Apple or Chrome app stores work, but on Android the user 
doesn't have a standard way to obtain the developer's key, so the app store 
could sign a modified binary with any key.

In any case, verifying a signature or hash against a public key or expected 
hash (obtained how?) is currently a manual process that non-experts can't be 
expected to carry out, let alone understand. What I'm looking for is a way to 
automate that process to protect non-experts.

As far as I can see, locked-down platforms like iOS and ChromeOS make it 
impossible in theory to tell whether the trust root (Apple/Google) is providing 
binaries built from published source code, because there's no way to get a 
verifier onto the device unless it's also approved (and potentially tampered 
with) by the trust root. But I think the situation for browser-downloaded 
software and Android apps might be less bleak.

One aspect that concerns me is rollback attacks: if the verifier accepts 
binaries that aren't listed in the public log, can the adversary tamper with 
the identifying attributes of the tampered binary (name, URL, etc) so the 
verifier doesn't realise there's a log entry that the binary should match?

Cheers,
Michael

Not having published in any app store, I'd like to know if my
assumptions here are incorrect.

I *think* that app stores take a binary you upload and run their
static and dynamic checks on that.  They then publish that binary
without modification.  (Indeed, how could they modify it?  You sign it
with your key.)  In that case, I think a verifiable build system ala
Gitian would work well.

The trust web is such that knowledgeable users can replicate a build
to a hash.  That hash is what anyone downloads via the App Store, and
less knowledgeable users, but users running rooted phones, can pull
the binary off and check the hash.  That hash is what's signed by the
developer's private signing key.  The app store can't substitute a
different binary (no developer signing key), users can verify that the
app was what the developer produced (via pulling the binary and
checking the hash), and advanced users can verify that what the
developer produced is what they produce via the replicable build
process.

If we assume that app stores aren't going away any time soon, we need
to address this problem: How can a user who downloads an app from an
app store be satisfied that it was built from published source code?

We might also think about how to solve the problem for apps downloaded
through browsers.

Verifiable builds are necessary but not sufficient here - they allow
an expert auditor to tell whether the binary she downloaded was built
from the published source, but an attacker might target the binaries
downloaded by certain other users without alerting the auditor. So we
also need a way for a non-expert user to tell whether the binary she
downloaded matches the one that was audited.

PGP signatures and hashes aren't currently usable by non-experts, and
signatures or hashes published through the same channel as the binary
can be tampered with in the same way as the binary.

Something along the lines of Certificate Transparency might be useful
here: a public log of software names, versions, and hashes, which a
browser or other download tool can use to verify downloaded binaries
without any manual steps needing to be taken by the user. Software
publishers would be responsible for adding entries to the log for
their own software and monitoring the log for entries added by anyone
else.

Michael

Is that helpful though?

CryptoCat is served up by the Chrome app store. Do you have control
over what binary gets distributed to who? Does any assurace exist
beyond the app store's own signing validation?

I thought this was like webmasters and third-party script inclusions.
They will be blind if Google or DoubleClick are compelled to
selectively swap out the scripts they serve to millions of third-party
sites.

That would be the Digital Rights Watch, I believe (http://diriwa.org), though
it is/was much more ambitious, and aims to collect all available relevant

Thankfully Cryptocat can be used with a custom server. They can shut down a 
server but they can't prevent new servers being configured. 
Hence the importance of decentralized open-source software.

You should think about splitting Cryptocat software development and
service operation into two separate legal entities. Service operation
could legally be based in whatever country, say, Antigua.

There was at least one wiki meant to collect information regarding the
legal requirements per country, but I don't remember where.

To be true, i invested 4 weeks of trolling on IETF WebRTC mailing list
sustaining the need to support "also SDES" in order to provide
interoperability with existing VoIP world from day 1.

The relevant point still was to still have DTLS-SRTP (that's still
inside) in place but to ADD a a modular / end-user-verifidable
(appropriate JS API) security fingerprint / security model.

When i unsubscribed from the DTLS-SRTP mailing, the WebRTC standard was
WITH "end-to-end" encryption but WITHOUT end-to-end-authentication
(relying on the server to provide authentication means for user
fingerprint, de-facto allowing MITM).

Which is the current status for fingerprint verification of DTLS-SRTP
calls? Does it still rely on server?

Firefox nightlies, as far as I'm aware, also provide WebRTC capability 
these days (based on DTLS-SRTP... they voted down at last week's IETF 
87 WebRTC/RTCweb support for SDES (which channels keying material

Yup, Cryptocat has had build assurance for quite some time. "Sorry, not 
possible to backdoor without people noticing" is still a valid line of defence 
and has been one for a while.

But I guess it was still worth it to tweet that in the event that even that 
line of defence is somehow circumvented, in the (unlikely, I know) circumstance 
that we get some sort of legal order that's definitely beyond our capacity to 
swerve around, then yeah, Cryptocat would rather cease development. It's just a 
simple extra assurance.

You should consider testing CryptoCat with OpenFire XMPP Server.

This is because with OpenFire + Chrome you can also do end-to-end
encrypted WebRTC Audio/Video call.

So the right Recipie is:
- OpenFire as XMPP server http://www.igniterealtime.org/projects/openfire/
- CryptoCat as a Chat+Filetransfer client Client (for Chrome Plugin)
- Chrome as a Secure Audio/Video client with WebRTC

Everything can be setup by a Poweruser with no specific ninja Linux skills.

If someone want to make this recipie working, i think that the world
would appreciate with an

"easy to be setup, independently run, audio, video, file transfer, chat
infrastructure accessible with a web browser" .

Would implementing some sort of build assurance thing like Tor have
done recently help here? So if the government said "please put a
back door for us", you could legitimately say "sorry, not possible
without people noticing". That's an even better option than
"crypto.cat is now closed, you may like to complain to the US
government about that."

such a build against what's on one of the browser extension / addon

I don't remember that, but I do remember hearing the FISC ruled some of the 
NSA's activities unconstitutional….in 2011.

The ruling was classified. Funny how that works.

"They" better be global then. And "they" better be able to deal
with distributed systems, where seizure of a fraction of a system
does not produce any actionable items, nor clues about physical
whereabouts or monetary streams to trace.

My Fellow Users,

I have been forced to make a difficult decision: to become complicit in crimes 
against the
American people or walk away from nearly ten years of hard work by shutting 
down Lavabit.
After significant soul searching, I have decided to suspend operations. I wish 
that I
could legally share with you the events that led to my decision. I cannot. I 
feel you
deserve to know what's going on--the first amendment is supposed to guarantee 
me the
freedom to speak out in situations like this. Unfortunately, Congress has 
passed laws that
say otherwise. As things currently stand, I cannot share my experiences over 
the last six
weeks, even though I have twice made the appropriate requests.

What's going to happen now? We've already started preparing the paperwork 
needed to
continue to fight for the Constitution in the Fourth Circuit Court of Appeals. 
A favorable
decision would allow me resurrect Lavabit as an American company.

This experience has taught me one very important lesson: without congressional 
action or a
strong judicial precedent, I would _strongly_ recommend against anyone trusting 
their
private data to a company with physical ties to the United States.

Sincerely,
Ladar Levison

2013-08-08 Thread Kyle Maxwell
I find it unlikely that it's an NSL per se. That would compel Lavabit
to produce existing business records, and shutting down doesn't
provide any defense against that.

But if the FBI (likely the lead agency on this) tried to compel
Lavabit to weaken its implementation so that they could conduct
ongoing, future surveillance, that might be a different matter. My
guess is that the actual issue lies more in this direction.

It is profoundly encouraging to see that people of such courage and
integrity as the Lavabit staff exist, and are willing to put everything
on the line to stand up against this madness.
