Root Causes: A PKI and Security Podcast

Latest Episodes:

Root Causes 67: Definition of DevOps and DevSecOps Feb 21, 2020

Show notes

Our hosts are joined by senior DevOps engineer David Colon to explore what DevOps means in today's enterprise. They cover diverse aspects of the DevOps phenomenon, including cultural implications, "configuration drift," definition of release velocity, and DevSecOps. Plus of course how DevSecOps intersects with PKI.

Root Causes 66: Functional Versus Homomorphic Encryption Feb 18, 2020

Show notes

Traditionally, file encryption is an all-or-nothing affair where data cannot be gleaned from the encrypted file without fully decrypting its contents. A new brand of cryptography called homomorphic encryption makes it possible for specific types of data to be read from a file while the rest of it remains encrypted. Join our hosts as they explain this new technology approach and its possible implications and use cases.

Root Causes 65: Quantum Key Distribution Feb 10, 2020

Show notes

Quantum key distribution is a new technology that uses the principles of quantum physics to generate and distribute truly random keys for encrypted communication. Join us as we explain how quantum key distribution works, why it is not the same as quantum safe cryptography, and which cases it may be useful for.

Root Causes 64: What Is Digital Identity? Feb 04, 2020

Show notes

The phrase "identity is the new perimeter" has gained in use of late, reflecting the reality that today's modern enterprise architecture is a mix of traditional and cloud, owned and rented and BYOD, all together in a complex mix. Under those circumstances identity is key to determine which digital entities have which permissions. But what do we mean when we say identity? Join our hosts as they explain the concepts behind digital identity, how they compare to our offline ideas around identity, and how these ideas shape computer security.

Root Causes 63: What Is CAA? Jan 29, 2020

Show notes

CAA, which stands for CA Authentication, is the capability for the domain name owner to specify in DNS which CAs are allowed to issue SSL certificates for a specific domain. Join us to learn more about CAA, including how it works and its potential benefits to businesses.

Root Causes 62: Windows CryptoAPI Spoofing Vulnerability Explained Jan 22, 2020

Show notes

On January 14 Microsoft announced a sweeping vulnerability that makes it possible to defeat the authentication of Elliptic Curve Cryptography (ECC) on Windows 10 and Windows Server systems, making it possible to create fake certificates on trusted roots that will fool these systems. Join our hosts and guest Nick France, CTO of SSL at Sectigo, as we explain this vulnerability, how it could be used in exploits, and what must be done to address it.

Root Causes 61: Anatomy of a Cryptocurrency Jan 10, 2020

Show notes

In our ongoing series about blockchain, we explore the technology, process, and ecosystem needs for a successful cryptocurrency. Join our hosts along with expert guest Alan Grau as we discuss the technology and ecosystem specifics of cryptocurrencies, including blockchain and PKI.

Root Causes 60: Fundamentals of Blockchain Jan 06, 2020

Show notes

Widely understood to be the technology behind popular crypto currencies, blockchain has become a household word. But what it blockchain really, and how does it work? Join our hosts and returning guest Alan Grau as they explain how blockchain functions, its strengths and weaknesses, and some of the other potential applications for this technology.

Root Causes 59: What Is Certificate Transparency? Dec 30, 2019

Show notes

Certificate Transparency (CT) is a recent and important development in the world of SSL certificates. Popular browsers require trusted CAs to log all SSL certificates to publicly available CT Logs. Join our hosts to find out how various parties are using CT Logs to learn about CA behavior and SSL usage patterns and to improve the overall quality of public trust.

Root Causes 58: 2019 Lookback - One Year of Podcasting Dec 16, 2019

Show notes

Nearly a year ago our hosts launched Root Causes to provide a forum for discussion of the issues surrounding the critically important PKI technology. Now at the end of 2019 we discuss how this podcast has taken shape, how that compares to our original expectations, and what we are looking forward to in 2020.
