    The rapidly increasing field of lattice-based cryptography is one of the effective tools in quantum computing meant to replace the existing public-key systems. The mechanism FrodoKEM has been customized as an alternative encapsulation mechanism recently, which in fact is submitted to the post-quantum NIST process for standardization. In this setting, security is conditional on utilizing standard lattices and learning through tracing-correcting errors. In any case, the excessive number of parameters makes it difficult for the embedded systems to function properly. This approach based on the FrodoKEM scheme entails parameters allowing for its integration into smaller-sized devices through the means of basic lattice-based cryptography. This thesis proposes harnessing two low-cost microcontrollers, namely STM32L552 and STM32WL55JC1, fostering better performance for post-quantum cryptography on smaller-sized devices. For the needs of the implementation of the scheme, STM32L552 required two different implementations, one involving usage of 1-way cache and the other the usage of 2-way cache; as for STM32WL55JC1, due to the small storage capacity of the RAM, Flash was used to reduce RAM space. Thanks to the versatility of WLSSJC1 showcasing connectability to a LoRa Network, which is based on wireless technology, the findings of this process can prove valuable for an IoT system.
