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. This is done by 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 applying PQC algorithms in the IoT space is not limited to considering space and time requirements. Key and ciphertext sizes must be kept within limits to effectively transport them via low bandwidth communication protocols like LoRaWAN, BLE, and NB-IoT.

The objective 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.
