Andy Bruce is the Lead Engineer at TripleCyber, where he works on crypto library integration, build infrastructure, and cloud integration, helping organizations prepare for the post-quantum future.
The security of our digital data relies heavily on cryptography — mathematical armor that protects everything from banking transactions to military communications. But a new threat looms with the capability to shatter it: quantum computing.
Classical vs. Quantum Computing
"When you have traditional classical cryptography, it's based on values which are ultimately stored as zeros and ones — individual bits of information. With quantum computers, you're not limited to just 0 or 1 for your values. You can have multiple values simultaneously," explains Andy Bruce, Lead Engineer at TripleCyber.
This fundamental difference creates an advantage for certain types of calculations. To visualize this, Bruce offers a compelling analogy:
"Using the analogy of a maze, if you want to solve multiple paths with a classical computer, you first have to try one path and come back to the beginning. Try another path, back to the beginning. Try another path. With a post-quantum computer, you can, in theory, try as many different paths simultaneously as you have qubits."
Why Today's Encryption Is at Risk
Today's security is based on mathematical problems that prove extremely difficult for classical computers to solve. Breaking RSA 2048 encryption — the standard protecting most web servers — would take a traditional computer approximately 19.8 trillion years to crack. A sufficiently powerful quantum computer could reduce that to a matter of hours or days.
This is not a distant hypothetical. Nation-states and well-funded adversaries are already collecting encrypted data today with the explicit intention of decrypting it once quantum computing matures — a strategy known as "harvest now, decrypt later."
The threat extends across every sector:
- Financial services — banking transactions and payment systems
- Healthcare — protected patient records and medical communications
- Government and defense — classified communications and national security infrastructure
- Critical infrastructure — power grids, water systems, and logistics networks
What Post-Quantum Cryptography Solves
Post-quantum cryptography (PQC) refers to cryptographic algorithms specifically designed to resist attacks from both classical and quantum computers. Unlike traditional approaches built on integer factorization (RSA) or elliptic curve mathematics (ECC), post-quantum algorithms are grounded in mathematical problems that remain hard even for quantum systems — such as lattice-based problems and hash-based signatures.
In 2024, NIST finalized its first set of post-quantum cryptographic standards, providing a clear roadmap for organizations to begin migrating their security infrastructure.
TripleCyber's Approach: TripleQuantum PKI
At TripleCyber, the response to this challenge is TripleQuantum PKI — a certificate-less, quantum-resistant Public Key Infrastructure designed to integrate seamlessly into existing security architectures.
Key capabilities include:
- Quantum-resistant encryption using NIST-approved post-quantum algorithms
- Real-time key issuance, validation, and revocation to eliminate stale credentials
- Certificate-less operation that removes the attack surface of traditional certificate authorities
- Modular, cloud-native design that evolves as cryptographic standards advance
- Seamless integration with TripleEnable's Zero Trust identity zones (Anonymous, Verified, Secure)
The Time to Act Is Now
"The security of your data depends on taking action before quantum computers are powerful enough to break current encryption," Bruce emphasizes. Organizations that wait until quantum computers are widely deployed will find it too late to protect data that was captured years earlier.
The transition to post-quantum cryptography requires time — updating cryptographic libraries, replacing legacy authentication methods, auditing dependencies, and retraining security teams. Starting now is the only way to ensure continuity of protection.
