OK, in order for me to correct this in the paper I need the following information:

1. A link to who "DFN" is.
2. A 'yes' or 'no' as to whether DFN is a root cert that browsers are shipped with (and details about this, like, do all 3 major browsers include DFN?)
3. A link to a paper, a blog post, or an article somewhere that describes in detail your side of the argument

Let me emphasize that none of this ultimately matters to the points that were made in the paper.

Whether the number is 600+ or 300+, it's still an insecure, broken mess.

I'll be happy to clear this up:

- Bitcoin is not the "market leader" of distributed DNS systems. Namecoin is.
- Namecoin and Bitcoin are designed with completely different goals in mind. They are not competitors.
- Namecoin is not intended to be a bitcoin replacement, nor the other way around. It is not like "litecoin" or any of the other bitcoin competitors, because it is not a competitor to bitcoin.

> Gold Age, eGold, Liberty Reserve. All the ones that were taken apart by the Feds.


I'll be happy to clear this up too:

None of these are comparable to Bitcoin or Namecoin.

Neither "Gold Age", nor "eGold", nor "Liberty Reserve" were truly decentralized, distributed currencies.

- "Gold Age" was not a currency: https://en.wikipedia.org/wiki/Gold_Age
- eGold: Centralized currency with no "reliable user identification" (not a problem with Bitcoin or Namecoin)
- Liberty Reserve: Centralized currency https://en.wikipedia.org/wiki/Liberty_Reserve#Background

People who are standing back and scratching their heads, wondering why Bitcoin is still around after years of being used to purchase illegal drugs, murder-for-hire, and weapons (continuing to this day btw), simply don't understand what Bitcoin is.

Do you represent a company that sells SSL certs? It seems like you might:

During twelve years as Principal Scientist at VeriSign Inc.,

Perhaps the paper is a bit harsh (and I welcome suggestions to improve its language), but the critiques it levies against companies that sell SSL certs are completely valid:

Companies that sell SSL certificates usually claim that their certificates provide customers with “security.” Customers are led to believe that these certificates protect browser-server communication from eavesdropping and tampering. As elaborated in this paper, this simply isn’t true today.

I have to say, that among the cert companies websites that I looked at, VeriSign's homepage makes the fewest claims about the security protections it provides.

The words "usually claim" leaves room for exceptions. I could not find, on the customer-facing pages on VeriSign's site, any claims that VeriSign's SSL certs "protect browser-server communication from eavesdropping and tampering."

Some close calls are:

In short, when it comes to securing online transactions, safeguarding customer information, and protecting business reputation, you're only as safe as the Certificate Authority you choose.
https://www.symantec.com/ssl-certificates-advantages

Customers Gain Confidence with the Green Address Bar: Online shoppers recognize the green address bar as an easy and reliable way to verify the site identity and security.
https://www.symantec.com/verisign/ssl-certificates/secure-site-pro-ev?fid=ssl-certificates

VeriSign's SSL certificates do not provide websites with meaningful protection as defined in the DNSNMC paper because they cannot be securely authenticated in the face of a fraudulent certificate that's presented to customers by a MITM.

If your certs can simply be replaced by any of the other CAs out there, then *all* of the security they provide is thrown out the window.

Furthermore, because VeriSign is a random third-party, not the company that user's visit when they visit a site using VeriSign's certificate, the protection offered by that certificate is inherently inferior to a securely authenticated self-signed certificate.

This is simply mathematics, and not a point that's up for debate.

When trust is distributed across more parties, that trust is diluted because it now depends on the least secure of those parties.

Sidenote:

It seems like I was sent "to the sharks" so to speak (perhaps as a practical joke?).

So far almost half of the replies to this thread have come from representatives of SSL companies.

The hostility is therefore no surprise.
