Quantum computers are envisioned to be able to solve mathematical problems which are currently unsolvable for conventional computers, because of their exceptional computational power from quantum mechanics. Therefore, if quantum computers are ever built in large scale, they will certainly be able to solve many hard problems, including the problems which the current public key cryptography is constructed upon. To counteract this problem, post-quantum cryptography protocols are required to preserve the security in the presence of quantum adversaries. Regardless of whether we can estimate the exact time for the advent of the quantum computing era, security protocols are required to be resistant against potentially-malicious power of quantum computing.

In this thesis, the main focus is devoted on the performance improvement of one of the potential PQC candidates, isogeny-based cryptography. Several optimized implementation of cryptography applications based on this primitive on different platforms are presented. From a general viewpoint, the proposed methods, implementation techniques and libraries have a practical impact in the performance evaluation of post-quantum cryptography schemes in a wide range of applications. In particular, the provided benchmarks and optimizations on ARM-powered processors provide a reference for comparison and evaluation of isogeny-based cryptography with other post-quantum candidates during the first round of NIST's PQC standardization process.
