The IAB approved the response to the liaison on IPv6 work items. Lee Howard will work with Scott Mansfield and Cindy Morgan to get the liaison statement posted in the appropriate places.
9. Tech Chat: Censorship, Freedom of Speech, and Architecture
Steve Bellovin joined the IAB to give a tech chat on “Censorship, Freedom of Speech, and Architecture.”
The slides are available at: <https://www.cs.columbia.edu/~smb/talks/Internet-censorship.pdf>
Steve Bellovin observed that there are two types of censorship we see on the Internet today: blocking information entirely, and drowning it out. Governments and corporations are both implicated in this censorship.
Governments can block access to certain destinations, look for and delete undesirable content, and use social and regulator pressure to discourage creation of undesirable content.
Corporations can control access to content, which is exacerbated when there is a limited choice of ISPs. Creating interesting content takes resources, and so there is a feedback loop: the bigger a corporations, the better content they can create, which attracts more people and makes the corporation even bigger. Corporations profit when people spend time on their sites, and so the expend effort to keep people there (which means they don’t have time to look at other content).
Steve Bellovin said that to solve censorship, we need:
- Ubiquitous encryption, to thwart content-based filtering
- Opaque metadata, to thwart packet filters and routing attacks
- No visible queries
- And do all of this without incurring the expense of Tor.
Steve Bellovin suggested that in the short term, we shouldP
- Encourage encryption
- Encourage anonymity technology, including unlinkable credentials
- Work on address agility
- Work on invisible replacements for the DNS
Potential longer term solutions include:
- m of n coding
- Name-based networking
- Getting rid go centralized systems
- Peer-to-peer CDNs
Some of this technology exists, but other items don’t exist yet or are too expensive to deploy. There may also be legal obstacles in certain countries.
Martin Thomson asked about the underlying premise that avoiding censorship is a natural good. Steve Bellovin replied that different cultures view things differently and make different tradeoffs.
Jari Arkko asked what happens when sources are biased. Steve Bellovin replied that corporations are an issue because they are the source of most content. The Internet has democratized access to minor voices, but as things become more concentrated, the minor voices get harder to find.
Erik Nordmark pointed out that there is a societal tension in that we want free speech and anonymous free speech, but we also want accountability. Steve Bellovin replied that studies actually do not support the notion that people behave better on non-anonymous networks. In small communities, social pressure works, but in large ones it does not.
