Advances in the realization of quantum computers are a real threat to our security and privacy. There is ongoing research on making our computers and connected devices secure against quantum computers called post-quantum cryptography.
In this talk, we will explain available solutions and present our research findings on the highly-optimized software libraries for post-quantum cryptography, based on Supersingular Isogeny Key Encapsulation (SIKE) protocol on Armv8 processors. SIKE is one of the candidates submitted for standardization and, due to its smallest key requirements, is more suitable for embedded devices. We demonstrate the performance results in an Arm-based smartphone.
