2015 – Looking Back, Moving Forward

Looking Back at 2014 End of 1024-Bit Security In 2014, the SSL industry moved to issuing a minimum security of 2048-bit RSA certificates. Keys smaller than 2048 are no longer allowed in server certificates. In addition, Microsoft and Mozilla started to remove 1024-bit roots from their certificate stores. Hopefully, the key size change will support users through to 2030. Push to Perfect Forward Secrecy Following the Edward Snowden revelations of pervasive surveillance, there was a big push to configure web servers to support Perfect Forward Secrecy.
Code Signing Baseline Requirements
October 20, 2014 by Jeremy Rowley CA/Browser Forum CASC Code Signing Malware Microsoft Vulnerability
Code signing certificates are used to sign software objects to authenticate that they originated from a verified source, allowing developers to avoid warnings commonly displayed by application software vendors such as Microsoft operating systems and Java. A fraudulent code signing certificate can wreak havoc on networks, spreading malware and adware without restraint. Certificate Authorities are tasked with ensuring that code signing applicants are legitimate entities and provide accountability for use of the certificate.
Who Sets the Rules Governing Certification Authorities?

Every time something positive is published about SSL and encryption,such as Google’s recent decision making use of https encryption a favorable rating factor for a website, or negative, such as the Heartbleed issue – bloggers and others always post questions about public Certification Authorities (CAs), including general questions on who sets the rules that govern CAs. Some bloggers seem to assume there are no rules or standards, and that CAs can operate without any requirements or limitations at all — that’s incorrect.
In the Wake of Unauthorized Certificate Issuance by the Indian CA NIC, can Government CAs Still be Considered “Trusted Third Parties”?
July 24, 2014 by Ben Wilson CA/Browser Forum CAA CASC Chrome ETSI Firefox Google Microsoft Mis-issued Mozilla OCSP PKI Policy Revocation SSL/TLS Trust List WebTrust
Short answer: Government CAs can still be considered “trusted third parties,” provided that they follow the rules applicable to commercial CAs. Introduction On July 8 Google announced that it had discovered several unauthorized Google certificates issued by the National Informatics Centre of India. It noted that the Indian government CA’s certificates were in the Microsoft Root Store and used by programs on the Windows platform. The Firefox browser on Windows uses its own root store and didn’t have these CA certificates.
What To Do When You Rely on Internal Names in TLS/SSL Certificates
July 18, 2014 by Wayne Thayer Attack CA/Browser Forum Firefox IANA ICANN Microsoft MITM Qualified SSL/TLS
A deadline set by the CA/Browser Forum for the use of Internal Names is quickly approaching, and many system administrators need to understand how best to adapt to this change. At the same time, hundreds of new top-level domains are being launched, which redefines what constitutes an Internal Name. In this post we’ll explain what the changes are, why they’re being made, and how you can update your systems in response to the problem.
Benefits of Elliptic Curve Cryptography
June 10, 2014 by Wayne Thayer CA/Browser Forum ECC ECDH ECDSA Encryption RSA SSL/TLS
Elliptic Curve Cryptography (ECC) has existed since the mid-1980s, but it is still looked on as the newcomer in the world of SSL, and has only begun to gain adoption in the past few years. ECC is a fundamentally different mathematical approach to encryption than the venerable RSA algorithm. An elliptic curve is an algebraic function (y2 = x3 + ax + b) which looks like a symmetrical curve parallel to the x axis when plotted.
When to Choose an Extended Validation Certificate
March 25, 2014 by Wayne Thayer CA/Browser Forum EV SSL/TLS
In our last post, we made a case for using Organizationally Validated (OV) or Extended Validation (EV) certificates for e-commerce, but we didn’t go into detail about the differences between OV and EV. EV certificates provide the highest level of assurance about your business, and they visually indicate this to your site’s visitors. The telltale sign that a business has obtained an EV certificate for their website is commonly referred to as the “green bar” displayed in the browser.
2014 – Looking Back, Moving Forward

Looking Back at 2013 Protocol Attacks The year started with a couple of SSL/TLS protocol attacks: Lucky Thirteen and RC4 attack. Lucky Thirteen allows the decryption of sensitive information, such as passwords and cookies, when using the CBC-mode cipher suite. Lucky Thirteen can be mitigated by implementing software patches or preferring the cipher suite RC4. That being said, RC4 was also attacked, where through 16 million sessions a small amount of plaintext can be recovered.
ICANN’s Accelerated gTLD Delegation Process and How This Impacts Your Organization
December 18, 2013 by Jeremy Rowley Announcement CA/Browser Forum CASC ICANN MITM Mozilla PKI Policy Qualified Revocation SSL/TLS Vulnerability
After the CASC’s previous letter addressing ICANN’s proposal to delegate nearly 2000 new gTLDs for use on the public Internet, ICANN identified and initiated an extensive study on two significant security issues. Now, based on the conclusions of the studies, ICANN is moving forward quickly with the delegation process, delegating more than 30 in the last two months alone. With ICANN ramping up the delegation process, nearly all 2000 will be delegated under the new rules, with only .
How Organizations Are Authenticated for SSL Certificates
November 22, 2013 by Kirk Hall CA/Browser Forum CSR DV EV Identity OV Phishing Policy SSL/TLS
Certification Authorities (CAs) are trusted third parties that authenticate customers before issuing SSL certificates to secure their servers. Exactly how do CAs authenticate these organizations? And where are the rules that determine what CAs must do during authentication? The Rules on Customer Authentication In the past, there were no common rules applicable to CAs as to minimum steps required to authenticate a customer before issuing an SSL certificate. Instead, each CA was permitted to create its own authentication processes, and was only required to describe the process in general terms in its public Certification Practice Statement (CPS).
