Crypto Software for Microcontrollers
Our mission is to provide size- and speed-optimized crypto software for IoT applications with large numbers of devices based on low-cost, resource-constrained microcontrollers. Typical examples are smart home devices such as thermostats and high-volume industrial sensors.

Our crypto software is designed to be tiny – and to take maximum advantage of Arm Cortex-M and RISC-V 32-bit hardware. |

It covers classic cryptography as well as all quantum-resistant algorithms admissible for CNSA 2.0 compliance. |

Writing correct cryptographic software is hard. Cryptographic software for deeply embedded systems, such as Internet of Things devices based on large numbers of inexpensive microcontrollers, is even harder – due to constrained memory sizes and processor speeds. Customers have found that our software has met this challenge, for example:
- "For our bootloader, there were hard limits regarding the memory consumption of crypto code. The ocrypto library of Oberon microsystems did simply fit. ... I can recommend Oberon's ocrypto library without any reservation."
- "Oberon microsystems understands embedded and we are proud to integrate their high-quality solutions in our devices."
