- Browsers don't send singular messages containing anonymous information. They send a complex
- sequence of messages to multiple parties with an interaction pattern and communication state.
- The more complex and encrypted the communication, the more uncommon state and direct
- communication is required, which makes it easier to track a person across multiple requests
- until the user's identity is revealed. Furthermore, with TLS in place, it becomes easy and
- commonplace to send stored authentication credentials in those requests, without visibility,
- and without the ability to easily reset those credentials (unlike in-the-clear cookies).
- Padding has very little effect. It isn't just the message sizes that change -- it is all
- of the behavior that changes, and all of the references to that behavior in subsequent
- requests, and the effects of those changes on both the server and the client.
- TLS does not provide privacy. What it does is disable anonymous access to ensure authority.
- It changes access patterns away from decentralized caching to more centralized authority control.
- That is the opposite of privacy. TLS is desirable for access to account-based services wherein
- anonymity is not a concern (and usually not even allowed). TLS is NOT desirable for access to
- public information, except in that it provides an ephemeral form of message integrity that is
- a weak replacement for content integrity.
- If the IETF wants to improve privacy, it should work on protocols that provide anonymous
- access to signed artifacts (authentication of the content, not the connection) that is
- independent of the user's access mechanism.
- I have no objection to the IESG proposal to provide information *also* via https. It would
- be better to provide content signatures and encourage mirroring, just to be a good example,
- but I don't expect eggs to show up before chickens. However, I agree with Tony's assessment:
- most of the text is nothing more than a pompous political statement, much like the sham of
- "consensus" that was contrived at the Vancouver IETF.
- TLS everywhere is great for large companies with a financial stake in Internet centralization.
- It is even better for those providing identity services and TLS-outsourcing via CDNs.
- It's a shame that the IETF has been abused in this way to promote a campaign that will
- effectively end anonymous access, under the guise of promoting privacy.
