Quantropi
A firm whose QiSpace platform bundles a post-quantum public-key scheme, symmetric encryption and entropy delivery.
Why this is listed
The QiSpace platform is the whole catalogue and each of its three components is a quantum-secure product, which qualifies the firm whatever algorithm MASQ turns out to rest on.
- Scheme of its own
- The offering includes a cryptographic scheme the firm developed itself rather than one published as a standard. This is a statement about what is being sold, not about whether it works.
- Algorithm not named
- The site makes a post-quantum claim without naming the algorithm or family behind it, so a reader cannot tell from the site which cryptography they would be running.
Recorded from this subject’s own site, listed under Sources below.
Quantropi describes QiSpace as a platform of quantum-secure products for data, connected devices and communications. It names three components: MASQ, which it describes as post-quantum public-key cryptography; QEEP, which it describes as quantum-secure symmetric encryption; and SEQUR, which it describes as quantum entropy services including synchronised key distribution.
The site describes MASQ as novel post-quantum cryptography. Which algorithm or family that refers to is not stated on the page, so this entry does not say. The site also carries performance and timeline claims, which this entry does not carry, because what a directory can record is what a subject offers rather than how well it says the thing performs.
