kvanttiturvallisten

Kvanttiturvallisten refers to the concept of quantum-resistant cryptography. This area of study focuses on developing cryptographic algorithms that can withstand attacks from future quantum computers. Classical computers use bits that are either 0 or 1, while quantum computers utilize qubits that can represent 0, 1, or a superposition of both. This property, along with quantum phenomena like entanglement, allows quantum computers to perform certain computations, such as factoring large numbers, exponentially faster than classical computers.

Many of the cryptographic systems currently used for secure communication, such as RSA and ECC, rely on the computational difficulty of these factoring problems. A sufficiently powerful quantum computer could break these algorithms, compromising the security of sensitive data and communications. Kvanttiturvallisten algorithms aim to solve this problem by employing mathematical problems that are believed to be hard for both classical and quantum computers to solve. These include lattice-based cryptography, code-based cryptography, multivariate polynomial cryptography, and hash-based cryptography.

The transition to kvanttiturvallisten cryptography is a significant undertaking, requiring research, standardization, and widespread implementation across various technologies and systems. Organizations and governments worldwide are actively involved in developing and evaluating these new cryptographic standards to ensure long-term digital security in the post-quantum era. The goal is to have quantum-resistant solutions in place before large-scale quantum computers become a reality.
