Digital Trust Is Elusive – Are Qualified Trust Services A Solution?
May 1, 2020 by Sebastian Schulz Attack eIDAS ENISA ETSI Phishing Policy QTSP Qualified SSL/TLS Trust List TSP
A popular saying goes: “Trust takes years to build, seconds to break, and forever to repair.” While I wouldn’t completely agree, the idea isn’t wrong. In real life trust between two parties is established over some period of time, depending on a variety of factors. Have you ever wondered why you initially trust some people more and others less, even if you’ve never met them before? There are a complicated multitude of factors that influence our thoughts: the person’s appearance, tone of voice, title or rank, etc.

Chrome Kills Mixed Content for HTTPS
December 6, 2019 by Bruce Morton (Entrust) Attack Chrome Firefox Mixed Content Policy SSL/TLS
In a phased approach, Chrome plans to block mixed content on secure websites to improve user security. Most browsers already block some mixed content such as scripts and iframes by default. Chrome is amping it up by gradually taking steps to also block images, audio recordings and videos, according to a recent Google Security blog. Preventing mixed content to load will eventually result in HTTPS websites losing their security indicator downgrading the site to HTTP, which alerts visitors that the site is not secure.

The purpose of this article The purpose of this article is to demonstrate why I believe browser-based UI for website identity can make the web safer for everyone. I explain in great detail, the reasons why the UI and UX didn’t work in the past. And what’s left is only making the problem worse instead of better. Some people seem to find it difficult to consume my thoughts about the enforcement of “HTTPS EVERYWHERE”, free DV certs and the browser padlock.

Looking Back at 2018 2018 was an active year for SSL/TLS. We saw the SSL/TLS certificate validity period drop to 825-days and the mass deployment of Certificate Transparency (CT). TLS 1.3 protocol was finally completed and published; and Chrome status bar security indicators changing to remove “secure” and to concentrate on “not secure.” The CA/Browser Forum has been reformed, the London Protocol was announced and the nearly full distrust of Symantec SSL completed.

As the legendary coach of the NY Yankees Yogi Berra allegedly said, “It’s difficult to make predictions, especially about the future.” But we’re going to try. Here are the CA Security Council (CASC) 2019 Predictions: The Good, the Bad, and the Ugly. The Good Prediction: By the end of 2019, over 90% of the world’s http traffic will be secured over SSL/TLS Encryption boosts user security and privacy, and the combined efforts of browsers and Certification Authorities (CAs) over the past few years have moved us rapidly to a world approaching 100% encryption.

LONDON – (June 27, 2018) – The Certificate Authority Security Council (CASC), an advocacy group committed to the advancement of the security of websites and online transactions, announced at the CA/Browser Forum event in London the launch of the London Protocol – an initiative to improve identity assurance and minimize the possibility of phishing activity on websites encrypted with organization validated (OV) and extended validation (EV) certificates, which contain organization identity information (Identity Certificates).

Looking Back at 2017 2017 saw the end of SHA-1 in public trust SSL/TLS certificates and the start of Certification Authority Authorization (CAA) allowing domain owners to authorize their CA. A “Not secure” browser indication was propagated to push more websites to support HTTPS. There was also a change in the certification authority (CA) ownership with DigiCert acquiring Symantec’s SSL and related PKI business and Francisco Partners buying Comodo’s CA.

How Does the ROCA Attack Work?
November 9, 2017 by Tim Hollebeek Attack PKI ROCA RSA Web PKI
On October 17th, a group of Czech researchers announced they had found a way to factor the moduli of many RSA public keys generated by hardware produced by Infineon Technologies AG. The technical details were presented in a paper at the 2017 Computer and Communications Security conference, hosted by the Association for Computing Machinery on November 2nd. The technique only works against the key pairs produced by Infineon’s library, because it exploits the unique method they use to generate RSA primes.

The Latest on Certification Authority Authorization

Things are certainly heating up at the CA/Browser with exciting proposals surrounding inclusion of the Wi-Fi Alliance (WFA) as a subjectAltName otherName, new validation methods, and debates over how the CAB Forum will continue operating. One of these newly passed ballots requires all CAs to check and process a domain name’s DNS Certification Authority Authorization (CAA) resource record prior to issuing a digital certificate. Background RFC 6844 created CAA records as a method for domain owners to specify a policy on which certificate authorities are authorized to issue certificates for the associated domain.

Looking Back at 2016 Fortunately, 2016 was not a year full of SSL/TLS vulnerabilities. Although some researchers did prove old cryptography algorithms should be put out to pasture. The year showed the end of public-trusted SHA-1 SSL/TLS certificates. It also showed more transparency should be considered due to issues discovered with a few certification authorities (CAs). The great news is HTTPS is no longer the minority — after 20 years, connections using HTTPS has surpassed HTTP.
