Using encrypted connection to transfer keys or signed/signature code/files, allow software users to delegate their trust with a PKI TTPA (trusted third party authority), like public CA (Certificate Authority), to help in providing trusted connection in between the original developer/author's web server, and millions of worldwide users' computers, at any time. When the original author/developer's domain-name and name-server is signed by DNSSEC, and when used SSL/TLS public certificate is declared/shown in TLSA/DANE DNSSec DNS resource-record, (and when SSL/TLS Certs in the trust chain are pinned and used via HPKP technique by web servers), then a web-server's webpage or data can also be verified via another PKI TTPA: DNSSEC and DNS namespace maintainer ICANN, other than a public CA. DNSSEC is another form of PGP/GPG WOT but for name-servers; it creates a trusted-chain for name-servers first (instead of people/person), and then people/person's PGP/GPG Keys and fingerprints can also be added into a server's DNSSEC DNS records. So any users who want to communicate securely (or any software users), can effectively get/receive their data/key/code/webpage etc. verified (aka, authenticated) via two (aka, dual/double) trusted PKI TTPAs/Channels at the same time: ICANN (DNSSEC) and CA (SSL/TLS Certificate). So PGP/GPG key/signed-code data (or file) can be trusted, when such solutions and techniques are used: HKPS, HKPS+DNSSEC+DANE, HTTPS, HTTPS+HPKP or HTTPS+HPKP+DNSSEC+DANE. If a vast number of user's group create their own new DLV based DNSSEC registry, and if users use that new DLV (along with ICANN-DNSSEC) root-key in their own local DNSSEC-based DNS Resolver/Server, and if domain-owners also use it for additional signing of their own domain-names, then there can be a new third TTPA. In such case, any PGP/GPG Key/signed-code data or a webpage or web data can be three/triple-channel verified. ISC's DLV itself can be used as a third TTPA as its still used widely and active, so availability of another new DLV will become fourth TTPA.
