The PKI industry has been a sham since day one, and several root certs have been compromised by the proverbial "bad guys" over the years (for example, the "Flame" malware incident used to sign emergency Windows Update packages which mysteriously only affected users in Iran and the Middle East, or the Diginotar debacle, or the Tunisian "Ammar" MITM attacks etc). This of course is assuming that the FBI doesn't already have access to all of the root CAs so that on domestic soil they can sign updates and perform silent MITM interception of SSL and IPSEC-encrypted traffic using transparent inline layer-2 bridging devices that are at every major Internet peering point and interconnect, because that would be crazy talk. However, some form of authenticity and integrity is better than zero, which is what the majority of the current DNS system offers, and it is point and click trivial to perform MITM attacks with unauthenticated DNS, especially on local area network segments which are rarely protected with more than the Windows firewall. Even without a centralized PKI, stateless port 53 UDP DNS could benefit from some type of cryptographic security, but as with any standard seemingly related to privacy or confidentiality we are left with this DNSSEC quagmire of meetings and proposed meetings to talk about the next meeting to discuss how the committee will propose the next request for comment, ad nauseum. Bitcoin for example doesn't need hundreds of private companies with elaborate PKI documentation authentication services which are in reality just mental placebos for Joe Consumer when he updates his monthly Brazzers subscription, and it's doing just fine as the runner up for the next global world monetary standard. So with that said, I would still place my wager on the FBI being the source of these various privacy enhancing service delays and not some secret cabal of PKI execs that are engaging in standards committee subterfuge. _______________________________________________ The cryptography mailing list firstname.lastname@example.org http://www.metzdowd.com/mailman/listinfo/cryptography
