PQCympäristö

PQCympäristö is a term used in Finnish to describe a post-quantum cryptography environment. This refers to a computational and security landscape that is resilient to attacks from future quantum computers. Quantum computers, when fully developed, will be capable of breaking many of the public-key cryptosystems currently used to secure digital communications, such as RSA and Elliptic Curve Cryptography.

The development of a PQCympäristö involves several key areas. Firstly, it requires the research, standardization, and deployment of new cryptographic algorithms that are believed to be secure against both classical and quantum computers. These are known as post-quantum cryptography (PQC) algorithms. Prominent candidates include lattice-based, code-based, hash-based, and multivariate polynomial cryptography.

Secondly, building a PQCympäristö necessitates the transition of existing systems and infrastructure to use these new PQC algorithms. This is a complex and lengthy process that involves updating hardware, software, protocols, and security policies across various sectors, including government, finance, and telecommunications. The goal is to ensure that sensitive data and communications remain secure in the quantum era.

Thirdly, understanding and managing the risks associated with the transition is crucial. This includes considering the performance implications of new algorithms, the potential for implementation vulnerabilities, and the long-term security guarantees. The creation of a PQCympäristö is an ongoing effort that requires collaboration between cryptographers, computer scientists, policymakers, and industry stakeholders worldwide.
