Cybersecurity for the Post-Quantum Era
Course Overview
When you audit your systems, you find public key infrastructure (PKI) and certificate authority everywhere. In the post-quantum era, the majority of deployed PKI will be vulnerable. This could happen as soon as 2027.
When you look closer, you see key exchange and key agreement in your infrastructure. The method these systems use will become obsolete in the post-quantum era.
This instructor led online delivered course will teach you:
-
how to identify what is broken, weakened, or unaffected by the quantum computer
-
how to classify your data and signatures by protection lifetime
-
how to prioritize exposed and hard to replace systems
THURSDAY NOVEMBER 5, 2026
9am PST / 12 noon EST / 18h00 CET
Duration: One day, 6 hours of instruction including bio and meal break.
Learning outcomes:
-
We explain quantum computing at a level relevant to cybersecurity decisions
-
We describe how Shor's algorithm threatens RSA, Diffie Hellman, and elliptic curve cryptography. We also describe how Grover's algorithm changes symmetric key security margins.
-
We distinguish "harvest now, decrypt later" and "sign now, forge later" attacks and prioritize assets by confidentiality and authenticity lifetime.
-
We compare hash based, code based, and lattice based approaches for signatures, key agreement, and key encapsulation mechanisms.
-
We develop a quantum safe migration roadmap built on a cryptographic inventory and prioritization.
Deep dives:
-
We explore security foundations in hash functions rather than factoring or discrete logarithms.
-
We delve into error correcting codes as the foundation for key agreement algorithms.
-
We look at lattice primitives, what makes them "hard" for classical and quantum computers, and how they are used in key encapsulation mechanisms.
The Stakes Are High
Untrusted Updates
How do you know your updates are trustworthy in a post-quantum era? Avoid the uncertainty of pushing untrusted updates by learning these quantum safe algorithms.
Get Ahead of the Gridlock
Don't wait for a Black Swan event. Proactively replace hardware security modules, routers, and chip cards before an emergency. Avoid an unexpected incident.
Reduce Risk of Data Loss
The quantum computer may render current industry standards obsolete. This course will teach you to secure your assets.
What we bring to the table
I know what it feels like to have to lift and replace large portions of your security infrastructure while continuing to run your business. This is why I've spent the last twenty years helping security practitioners just like you to protect your assets.
What others are saying
Shawn Hymel
"I worked directly with Jason for several years, and his knowledge and skills in cybersecurity are genuinely impressive. He's a thorough engineer and an excellent teacher, which is a rare combination. I'd recommend any class or workshop he runs!"
You can secure your assets in the quantum computer era.
At Gromo, we know you are the kind of people who want to be future focused and steps ahead of the quantum computer threat. In order to be that way, you need Cybersecurity for the Post-Quantum Era course. The problem is that you may feel overwhelmed by where it all gets applied. We believe this can be addressed in our course. We understand how the quantum computer can threaten your data. That's why we detail which algorithms are vulnerable and how the quantum computer threatens your security assets. Here's how it works: register today, learn about where the new math gets applied, and begin to change your security posture to avoid quantum computer vulnerabilities. So you can stop being a sitting duck and start to get a step ahead of the quantum computer threat.
