Optimization studies of the CRYSTALS-KYBER post-quantum cryptographic algorithm Luiz F. C. Ferro, Felipe J. A. Rampazzo, Marco A. A. Henriques School of Electrical and Computer Engineering State University of Campinas (Unicamp) – Campinas, SP lfcerro01@gmail.com, f233261@dac.unicamp.br, maah@unicamp.br Abstract. The development of quantum computers is getting closer to reality, and as a result the public key cryptographic algorithms used in industry are threatened. In recent years, the National Institute of Standards and Technology (NIST) has been carrying out a research on promising quantum-safe cryptographic schemes. All of them demand high computational capability and large key sizes. This paper describes a study about possible optimizations on NIST third round candidate CRYSTALS-KYBER in order to reduce memory consumption and processing time in Intel i5 and ARM Cortex-M0+ platforms. 1. Introduction The public-key encryption schemes used in industry today are considered secure, as t
