Quantropi Inc., a Canadian quantum cybersecurity innovator exhibiting at the Quantum.Tech Conference in Boston, MA, Jun. 14 – 15, 2022, spoke to the inherent advantages of its ground-breaking technology as a superior “third alternative” for addressing the imminent quantum cryptographic threat. Quantropi’s CTO Michael Redding participated in a head-to-head discussion with executives from five other companies, each representing one of the two principal quantum security approaches currently under active development. The panel, titled “QKD vs. PQC vs. TrUE: Who’s the Betamax, who’s the VHS, and who’s the DVD?” took place at Quantum.Tech Boston, Marriott Copley Place, on June 14th at 2:20 PM EST.

Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) are the two main alternatives to Quantropi’s “TrUE” quantum security solution, where TrUE refers to the company’s QiSpace™ platform’s unique capability to provide complete cryptographic integrity in terms of Trust, Uncertainty, and Entropy.
QKD and PQC differ in their technical implementation and ideal use cases. Each approach has its own set of limitations.
QKD is a method of secure transmission of cryptographic keys that uses quantum mechanics to allow communicating parties to securely exchange cryptographic keys. QKD’s limited operating range in standard optical fiber (commonly used in classical computer networks) means that it requires special-purpose hardware, which makes it enormously expensive and difficult to implement. More specifically, QKD is susceptible to denial-of-service attacks, and cannot authenticate the source of a transmission, making it vulnerable to so-called “man-in-the-middle attacks.
PQC refers to cryptographic algorithms containing math puzzles too complex for quantum computers to crack. Because PQC algorithms typically rely on keys much larger than those used in classical algorithms, more storage space is consumed and the time required to encrypt, decrypt, and verify messages is increased, which reduces performance and may prevent operation on resource-constrained cell phones or IoT devices. Furthermore, PQC algorithms cannot scale infinitely while maintaining their capacity to resist attacks. Most important, current PQC is limited to asymmetric encryption algorithms — i.e., the “Tr” element of “TrUE”.
“At this point, we see QKD as still something of a science experiment, albeit a promising one in the longer term; we believe the solution is our SEQUR™ SynQK product, which uses quantum gates to offer quantum-secure DIGITAL distribution of Quantum Keys over the existing Internet, even wireless networks, and which uniquely works in both today’s classical and tomorrow’s quantum systems,” said Michael Redding, Quantropi’s CTO. “As far as PQC, Quantropi’s MASQ™ product has exceptionally small key sizes; where you need to generate and authenticate a large number of digital signatures, such as in blockchains, MASQ™ will deliver quantum security, together with performance on par with or better than legacy cryptographic approaches,” added Redding.
“Every organization must take steps to protect against the immediate threat of Steal Now Crack Later, while starting the transition today to permanent post-quantum security; only our ‘TrUE’ QiSpace™ platform can provide a readily deployable, scalable, end-to-end solution,” said James Nguyen, CEO of Quantropi. “We believe TrUE will prove to be the DVD in this burgeoning new market.”
