Root Causes 665: What is Quantum Security Posture Management (QSPM)?
J
0:10Jason SorokoHOST
And the timing is right for this.
J
0:14Jason SorokoHOST
Quantum Security Posture Management, QSPM, Tim.
T
0:19Tim CallanHOST
QSPM, Quantum Security Posture Management.
T
0:23Tim CallanHOST
So we know what CSPM is, right? Cloud Security Posture Management.
T
0:33Tim CallanHOST
cryptography in particular.
T
0:35Tim CallanHOST
Am I getting that right?
J
0:37Jason SorokoHOST
Yeah, you've got it, Tim.
J
0:38Jason SorokoHOST
I think it reaches the same audience, the same kinds of people who procure solutions for cloud security and have to understand, have to do a lot of things and bundle a lot of technologies in order to be able to secure the cloud and all that that means.
Root Causes 664: What Is a Scientifically Relevant Quantum Computer? Part 1
J
0:00Jason SorokoHOST
Tim, we've talked about cryptographically relevant quantum computers.
T
0:05Tim CallanHOST
CRQC.
J
0:06Jason SorokoHOST
Yeah, and I think it's an important term because it kind of defines the point at which something like Shor's algorithm is viable.
J
0:20Jason SorokoHOST
This episode today is kind of a fun one because it's not the hardcore security.
J
0:27Jason SorokoHOST
They're all fun ones.
J
0:30Jason SorokoHOST
It's not the hardcore security, it's more about what's the real science that's also behind quantum computing? One of the things that inspired this, Tim, is some conversations I know you've had online, which people are asking, what's the point of spending all this money on quantum computing when it really doesn't do anything?
T
0:48Tim CallanHOST
Right, or I've heard the argument be made, let me get this straight, we're making this brand new computing architecture, and the only real purpose of it is going to be to break our cryptography? And the response to that is no, right? Absolutely not.
T
1:02Tim CallanHOST
And that isn't where it started.
Root Causes 663: The Trouble with Quantum Key Distribution
J
0:00Jason SorokoHOST
Tim.
J
0:00Jason SorokoHOST
Yes.
J
0:01Jason SorokoHOST
A thank you so much for being here with me in Ottawa.
J
2:19Jason SorokoHOST
What does the physics not secure is the title of this podcast, essentially.
J
2:26Jason SorokoHOST
Okay.
J
2:27Jason SorokoHOST
So I think we might throw up some graphics during this podcast, Tim.
T
2:32Tim CallanHOST
But I've got a little slide deck that you and I are going to talk through.
J
2:35Jason SorokoHOST
Okay.
Root Causes 662: HAWK Eliminated from NIST Competition, FALCON Unaffected
T
0:38Tim CallanHOST
Right?
J
0:38Jason SorokoHOST
Yeah, Tim.
J
0:39Jason SorokoHOST
Uh, so we reported on that in a previous episode.
T
0:42Tim CallanHOST
Correct.
T
4:49Tim CallanHOST
Uh, but in this case, it's good.
T
4:51Tim CallanHOST
Let's, let's eliminate these things before they're in production.
J
4:55Jason SorokoHOST
Tim, thanks for that, and thanks for reaching out to, uh, Dr. Dustin Moody, and thank you, Dustin, for, uh-
T
5:00Tim CallanHOST
Thanks, Dustin
Root Causes 660: What Are Delegated Credentials?
T
0:13Tim CallanHOST
Right.
T
0:15Tim CallanHOST
So Tim, if you're a content developer, content distribution network, a CDN,
J
0:22Jason SorokoHOST
okay.
T
0:23Tim CallanHOST
A cloud flare and Akamai.
J
3:04Jason SorokoHOST
right.
J
3:04Jason SorokoHOST
Thank you, Jay.
T
3:04Tim CallanHOST
Thank you, Tim.
Root Causes 659: Should We Lengthen Certificate Lifespans?
J
0:46Jason SorokoHOST
I think any of these regressive ideas, Anybody who's saying words like that fundamentally doesn't understand what PKI is doing for them.
J
1:02Jason SorokoHOST
Why do we have a cert rather than just a raw key pair, Tim?
T
1:06Tim CallanHOST
Right.
T
1:06Tim CallanHOST
Because you limit the risk window.
6 MINS LATER
T
7:18Tim CallanHOST
But because it works so resoundingly well, I think one of the things that can happen is we can just start to get cavalier about it.
J
7:32Jason SorokoHOST
And people are looking for ways to make their life easier.
J
7:37Jason SorokoHOST
And what really, here's my final thought on this, Tim.
J
7:40Jason SorokoHOST
It's very specifically something like shortening lifespans or lengthening the lifespans is a scale problem.
