Quantum Security FAQ
What is the "quantum threat," and why should I care now?
The quantum threat is the risk of quantum computers in the future being able to easily break today's standard encryption (RSA/ECC). It’s important to take action now because of harvest now, decrypt later (HNDL) attacks. Adversaries may already be storing your encrypted data, waiting to decrypt it and steal your secrets years from now once the quantum computer is ready. Since the defense (migration to PQC) takes years, you need to act today.
What does "harvest now, decrypt later (HNDL)" mean?
HNDL is when threat actors bulk-collect and store today's encrypted, high-value data. They are waiting until powerful quantum computers are available to easily decrypt and steal those secrets.
What is post-quantum cryptography (PQC)?
PQC is a new class of cryptographic algorithms designed to be secure against classical and quantum computers. These new algorithms, like those selected by NIST, will replace vulnerable public cryptography like RSA and ECC.
What is the difference between PQC and QKD?
PQC (post-quantum cryptography) is a software-based, scalable defense that uses complex mathematics to resist quantum attacks. QKD (quantum key distribution) uses the laws of physics and dedicated hardware (often fiber-based) to distribute uncompromisable cryptographic keys.
Do I need to "rip and replace" all my hardware right away?
No. The transition is primarily cryptographic. Fortinet's solutions support a hybrid mode that runs classical and quantum-safe algorithms simultaneously. This lets you introduce PQC gradually, mitigating risk while keeping legacy systems running without any overhead or disruption.
When will quantum computers be powerful enough to break my current encryption?
While the date is unknown, experts like Gartner estimate by 2034, quantum computing will be able break all cryptography. Since the migration is a multi-year process, planning and deployment must begin today to beat the deadline.
Is Fortinet's quantum solution compliant with NIST standards?
Yes. Fortinet solutions support the leading algorithms selected by the U.S. National Institute of Standards and Technology (NIST) for standardization. This ensures you are transitioning using approved, future-proof algorithms.
Which part of my infrastructure is most vulnerable today?
Any part of your infrastructure, including legacy equipment using public-key cryptography for key exchange or digital signatures, is vulnerable.
How can Fortinet help me start my quantum journey?
- Audit and understand your current posture
- Transition using built-in hybrid mode and crypto-agility tools
- Protect your data with high-performance, NIST approved quantum-safe encryption (PQC) integrated directly into FortiOS.
