A Network Analysis of Encrypted Voice over OSTN
Posted on July 5, 2012
| patch
Introduction to OSTN
The OSTN network stands for Open Source Telephony Network. It is a federated network standard for supporting Internet calling with end-to-end encryption ala ZRTP. Its very similar to e-mail in that VOIP calls can be routed to addresses such as user@domain.tld. Its a simple concept, but I believe it to be ground breaking implementation! Never before have I seen such an accessible solution to encrypted VOIP calls. OSTN is platform independent, is a federated network, and it is an open standard such that it is widely adoptable.

Freebird: Rio group picture via Obscuracam for Android What happens when you gather coders with privacy and security activists from around the world? Freebird! We held a simultaneous event in NYC and Rio, a one-day barcamp aimed to empower users to be more informed and engaged around their use of mobile technology, while engaging with developers to promote interest in open-source tools, security and privacy. Freebird was a pre-event for RightsCon:Rio, which allowed us to continue and extend conversations and ideas into the larger context of information technologies and human rights.

Orbot Data Tax (Updated!)
Posted on June 20, 2012
| patch
Update (6/26/12): I Found Orbot to have lower idle usage then previously recorded. The post now reflects the new statistics. The previous stats were based on idle usage at 92 bytes/s
There have been many inquiries about the cost of Orbot’s data usage. I ran five different tests to record the types of data tax a user might encounter. Heavy usage of Orbot combined with a low monthly data allotment could be an issue.

Auditing Twitter With Orbot
Posted on June 13, 2012

Twitter’s new Android application provides a proxy option that supports Orbot. It is a great way to access Twitter, particularly if Twitter is blocked. Check out the Orbot Your Twitter blog post! That post explains how to set up Orbot with Twitter, however, it came with an important disclaimer:
WARNING AND DISCLAIMER: Twitter for Android is proprietary, closed-source software. Details of the implementation of proxy support have not been publicly disclosed or audited by a third-party at this time.

We believe in protocols, not products. We believe in partnerships, not proprietary fiefdoms. We believe in building a community of collaborators, not a cacophony of criticism and unnecessary competition. We believe in practical solutions to perilous problems.
With all of this in mind, we are very happy to announce our partnership and support of the ChatSecure for iOS open-source free software project. Through our our two year history, we have been lucky to receive support from a variety of donors and funders, and we are now using what influence and opportunities we have to endorse other projects that we feel are compatible with our outlook and goals.

Yes, yes, we are trying to get in on all of the Facebook pre-IPO buzz. Fortunately, the headline is true – through
Facebook’s support for open-standards messaging, our secure mobile messaging app, Gibberbot for Android, can be used to communicate securely with any other friend on Facebook who is ALSO using a secure messaging app. Whether it is Gibberbot, ChatSecure for iOS, Adium (Mac), Pidgin (Windows/Linux), or one of the many secure messaging apps that support the Off-the-Record encryption capability, Facebook allows encrypted messaging between mobile and desktops alike.

Cross-Domain calling, or “toll-free long distance VoIP”
Posted on May 4, 2012

In a standard OSTN configuration, the Fully Qualified Domain Name (FQDN) of the server running Freeswitch is a core dependency to operate the service. For example, the domain ostel.me was first configured as a DNS record, a server was bootstrapped with ostel.me as the local hostname and a Freeswitch cookbook was run using the Chef automation system. Because the domain was configured both in DNS and locally, the cookbook has enough information to automatically build an operational OSTN node.

Singing and Dancing for Encryption
Posted on April 19, 2012

If you see me dancing or signing with my phone in my hand, I may not just be having a great time, but also creating an encryption key. Part of the issue with security is that it can often be difficult to implement or an added step in what users want to be an easy and seamless process. What if we can make secure and private communications fun and easy?

Call My Email

What if you could call me directly through my email? No exchanging of phone numbers or searching for handles on Skype. Just plain and simple email. Now what if we can make that phone call as secure as it is easy. That’s the goal of what we’re doing here at Open Secure Telephony Network (OSTN).
The internet is already structured to be able to do this. That’s why I can have all of my emails point to one email box if I want to.

Acrobits Groundwire – OSTN supports iPhone
Posted on March 21, 2012
| lee
The Guardian Project develops open source software primarily for the Android platform but we strive for security by design to be a part of all platforms. With OSTN, there are two major components. The the first is the server, which operates as the primary user directory and call switch. The other is the client, which is the program you interact with to send and receive calls.
While the Apple App Store forbids distribution of GPL licensed software from their service, the underlying protocols used by OSTN are open, so even iPhone developers may implement them in a proprietary client application without breaking any intellectual property laws.

Adventures in Porting: GnuPG 2.1.x to Android!
Posted on March 15, 2012
| Hans-Christoph Steiner
PGP started with Phil Zimmerman’s Pretty Good Privacy, which is now turned into an open IETF standard known as OpenPGP. These days, the reference OpenPGP platform seems to be GnuPG: its used by Debian and all its derivatives in the OS itself for verifying packages and more. It is also at the core of all Debian development work, allowing the very diffuse body of Debian, Ubuntu, etc developers to communicate and share work effectively while maintaining a high level of security.

February 2012: Project Update
Posted on February 9, 2012
| n8fr8
Through coordination with the Tor Project, we released Orbot 1.0.7, which includes an embedded version of OpenSSL to assure we have the latest security enhancements for this critical cryptographic library. In addition, compatibility testing was done on Android 4.0 (Ice Cream Sandwich) and with the latest versions of Firefox Mobile. As always you can learn more and download Orbot in the Android Market and at https://guardianproject.info/apps/orbot
With the public awareness of internet censorship and surveillence growing thanks to SOPA, PIPA and CarrierIQ, not to mention the ongoing unrest in many regions if the world, we have seen a huge spike in interest and download of Orbot, Orweb and Gibberbot.

These are interesting times, if you go by Times Magazine as an indicator. The magazine’s person of the year for 2011 was The Protester, preceded in 2010 by Facebook founder Mark Zuckerberg. Both entities partners with equal stake in freely sharing the digital content that shows the world what’s going on in it, at any time, from behind any pair of eyes.Also casting in their lot with the others is Time Magazine’s 2006 person of the year, You: the You that puts the “you” in “user-generated content;” the You whose miasma of bits, bytes, and the powerful images they express are becoming increasingly problematic.

I’ve co-written a blog post with Bryan Nunez of WITNESS, on some important concepts around using mobile video technology within activists and protest situations. It is up now on their blog, but here is a short excerpt:
Activists all over the world have turned to mobile phones to organize, coordinate and document their struggle. Images and videos shot on mobile phones have been the standard for what revolution looks like in the public imagination.

Don’t Get Burned, Anonymize Your Fire

Thanks to Jesse Vincent, aka @obra of the K-9 mail project, we can say that Orbot (Tor on Android) and Orweb (Privacy Browser) work just fine on the new Amazon Kindle Fire. This means that while everything you do through Amazon’s store and browser are tracked and accounted for by Team Bezos, you can use our apps to more safely and privately access web content through the Tor network. While we are mostly Nook Color fans around here, we know that the Kindle Fire is going to be quite popular this Christmas, and are glad to see that mobile privacy now has a toehold on the device from Seattle.

Greetings mobile believers,
I am about to head into the first ever Silicon Valley Human Rights Conference, aka #RightsCon, and though I would post some thoughts about the state of the Guardian Project, and the world in which we operate. RightsCon looks to be an amazing event (live streaming here: https://www.rightscon.org/), by an amazing organization (Access), and it comes at an interesting time in the world, and for our project.

ACLU believes “Software Developers Can Put Privacy First!” (and so do we!)

A bit more on our big win in the Develop4Privacy contest, from Brian Robick at the ACLU of Washington State:
When software developers put privacy first, everybody wins!
Too often, user privacy is an afterthought in the design of computer software and online services. In recent months, social networks have rolled back changes, cell phone manufacturers have altered the way that location tracking data is stored, and most recently, mobile application developers have been caught inappropriately collecting children’s personal data.
