Recent progresses in research and development of quantum computers may pose a threat to modern cryptography. When powerful enough quantum computers will be available, quantum algorithms will be able to easily break public-key cryptosystems that are used today in many different applications, like secure browsing. Fortunately, using some particular algebraic structures like lattices it is possible to build cryptosystems that are supposed to be quantum-resistant. In the last few decades several proposals of post-quantum key exchange protocols have appeared in literature, still they need some improvements in speed and data transfer for practical applications. Some of the performance bottlenecks of pure software implementations could be mitigated if custom hardware blocks are designed to accelerate part of the algorithms.
