MicroSec empowers organisations to take control over their environment through our unique approach of Security by Design at the Edge for IoT, IIoT and OT devices and networks, from proactively preventing attacks from the inside-out, stopping zero-day attacks on devices, preventing device and network intrusions, creating chains of trust between devices, and reducing your operational risks and costs starting from the device to the cloud.

MicroSec provides enterprise-grade PKI (Public Key Infrastructure) solutions to IoT devices. We also use our patented microcerts instead of traditional X509 certificates which are more amenable to being transported over low bandwidth protocols like BLE, NB-IoT etc.

However, some users may not be satisfied with this level of security with concerns about the power of quantum computing algorithms. In this case, one would need to rely on PQC (post-quantum cryptography) based techniques for key establishment and QKD (quantum key distribution) based techniques for key distribution.

The challenge in the application of PQC algorithms in the IoT space is not only the consideration of space and time requirements but also ensuring that the key and ciphertext sizes are kept within limits such that they can be effectively transported via low bandwidth communication protocols like LoRaWAN, BLE, and NB-IoT.

The objective then is to arrive at and implement a cryptographic scheme that has a reduction to a known NP-hard mathematical problem that is not solvable in polynomial time using any known quantum algorithms which are comparable to current ECC implementations on 32-bit ARM processors in terms of speed, memory requirements and code size with keys and ciphertext which can be effectively transported over low bandwidth protocols like LoRaWAN, Bluetooth, and NB-IoT.
