Ben Wizner: Not a lot of applause for us. Chris Saghoian: I know.

Ben Wizner: Are they ready? Chris Saghoian: I think so.

Ben Wizner: Ok, I think we'll get started. Thank you all so much for being here. There

wasn't a lot of applause when we came on stage so I guess you're here to see somebody else. (( Applause ))

My name is Ben Wizner; I'm joined by my colleague Chris Saghoian from the ACLU. Maybe we can

Edward Snowden: Hello. Ben Wizner: With his very clever green screen. Please bear with us today, the technology

may have some kinks. The video may be a little bit choppy. Our friend is appearing through

7 proxies so if the video is a little slow.

You're joining us for the event that one member of congress from the great state of Kansas hoped would not occur. He wrote to the organizers

or SXSW urging them rescind the invitation to Mr. Snowden. The letter included this very

curious line, "The ACLU would surely concede that freedom expression for Mr. Snowden has

declined since he departed American soil". No one disputes that freedom of expression

is stronger here than there but if there's one person for whom that's not true, it's

Ed Snowden. If he were here in the United States he would be in a solitary cell, subject

probably to special administrative measures that would prevent him from being able to

communicate to the public and participate in the historic debate that he helped launch.

We're really delighted to be here. One more bit of housekeeping. As I'm sure

most of you know, you can ask questions for Mr. Snowden on twitter using the hash tag

AskSnowden. Some group of people backstage will decide which of those questions we see

here. We'll try to leave at least 20 minutes or so for those questions. As I said, Ed Snowden's

revelations and the courageous journalism of people like Bart Gellman who you just heard,

Glenn Greenwald, Laura Poitras, and others has really launched an extraordinary global

debate. You might think of that debate as occurring over 2 tracks. There is a debate

in Washington in the halls of power about law and policy about what democratic controls

we need to reign in NSA spying that takes place in courts that are considering the legality,

the constitutionality of these programs in the legislature, considering legislation.

There's a very different conversation that you here in conference rooms in technology

companies, particularly among people working on security issues. Those people are talking

less about the warrant requirement for meta data and more about why the hell the NSA is

systematically undermining common encryption standards that we all use. Why is the NSA

targeting telecommunication companies, internet companies, hacking them to try to steal their

customer data, basically manufacturing vulnerabilities to poke holes in the communication systems

that we all rely on? We're hoping to mostly focus on that latter conversation here.

With that in mind, Ed if you're with us, maybe you could say a few words about why you chose

for some of your first public remarks to speak to the technology community rather than say

the policy community in Washington. Edward Snowden: Well thank you for the introduction.

I will say SXSW and the technology community, the people who are in the room at Austin right

now, they're the folks who can really fix things. Who can enforce our rights through

technical standards even when congress hasn't yet gotten to the point of creating legislation

to protect our rights in the same manner? When we think about what's happened with the

NSA in the last decade, in the post 9/11 era... the result has been an adversarial internet,

a sort of global free fire zone for governments that's nothing that we ever asked for. It's

not what we wanted. It's something we need to protect against.

When we think about the policies that have been advanced... sort of erosion of fourth

amendment protections, the proactive seizure of communications, there's a policy of response

that needs to occur. There's also a technical response that needs to occur. It's the makers,

it's the thinkers, it's the development community that can really craft those solutions and

make sure we are safe. The NSA... the sort of global mass surveillance

that's prying at all of these countries not just the US, and it's important to remember

that this is a global issue, they're setting fire to the future of the internet. The people

who are in this room now, you guys are all the firefighters. We need you to help us fix

this. Ben Wizner: So Chris, you heard Ed say that

the NSA offensive mass surveillance programs, the sort of manufacturing of vulnerabilities,

is setting fire to the future of the internet. Do you want to comment on that?

Chris Saghoian: Sure. Many of the communications tools that we all rely on are not as secure

as they could be. Particularly for the apps and services that are made by small companies

and small groups of developers, security is often an afterthought if it's a thought at

all. What that's done is enable global passive surveillance by the US but other governments

too. What I think has been the most lasting impression

for me from the last 8 months is the fact that the real technical problems that the

NSA seems to have are not, "How do we get people's communications" but, "How do we deal

with the massive amounts of communication data that we're collecting?" The actual collection

problem doesn't seem to be a bottleneck for the NSA. That's because so many of the services

that we're all relying on are not secure by default.

I really think for this audience, one of the things that we should be thinking about and

hopefully taking home is the fact that we need to lock things down. We need to make

services secure out of the box. That's going to require a rethink by developers. It's going

to require the developers start to think about security early on rather than later on down

the road. Ben Wizner: Let me pick up on that. Ed, you

submitted written testimony last week to the European parliament. I want to quote a very

short part of that and have you elaborate on it. You said, "In connection with mass

surveillance, the good news is that there are solutions. The weakness of mass surveillance

is that it can very easily be made much more expensive through changes in technical standards".

What kind of changes were you talking about and how can we ensure that we make mass surveillance

more expensive and less practical? Edward Snowden: The primary challenge that

mass surveillance faces from any agency, any government of the world, is not just how do

you collect to communications as they cross the wires, as they sort of find their way

through the global network, but how do you interpret them? How do you understand them?

How do you direct them back out and analyze them? [inaudible 00:08:35] at least on the

easiest, the simplest, most cost effective basis by encryption.

There are 2 methods of encryption that are generally used, one which is deeply problematic.

One of those is what's called key escrow. It's sort of what we're using with Google

type services, Skype type services, right now where I encrypt a video chat and I send

it to Google. Google decrypts it and then re-encrypts it to you guys and we have it.

End-to-end encryption, where it's from my computer directly to your computer, makes

mass surveillance impossible at the network level without a crypto break. They are incredibly

rare and they normally don't work. They're very expensive. By doing end-to-end encryption,

you force what are called threat model global passive adversaries to go through the end

heads, that is the individual computers. The result of that is a more constitutional,

more carefully overseen sort of intelligence gathering model, law enforcement model, where

if they want to gather somebody's communications, they'd have to target them specifically. They

can't just target everybody all the time and then when they want to read your stuff, they

go back in a time machine and they say, "What did they say in 2006?"

They can't pitch exploits in every computer in the world without getting caught. That's

the value of end-to-end encryption and that's what we need to be thinking about. We need

to go, "How can we enforce these protections in a simple, cheap, and effective way that's

invisible to [users 00:10:17]. I think that's the way to do it.

Ben Wizner: So Chris, one of the obstacles to widespread end-to-end encryption is that

many of us get our e-mail service from advertising companies that need to be able to read the
