Kvanttisuojatut

Kvanttisuojatut, also known as quantum-protected or quantum-safe, refers to systems, algorithms, and technologies designed to withstand attacks from quantum computers. Traditional encryption methods, such as RSA and ECC, rely on mathematical problems that are computationally infeasible for current classical computers to solve. However, a sufficiently powerful quantum computer, utilizing algorithms like Shor's algorithm, could efficiently break these widely used cryptographic schemes.

The field of quantum-protected cryptography aims to develop new cryptographic primitives that are resistant to quantum algorithms. This involves exploring different mathematical foundations, such as lattice-based cryptography, code-based cryptography, multivariate polynomial cryptography, and hash-based cryptography. These approaches are believed to be computationally hard even for quantum computers.

The development and standardization of quantum-protected algorithms are ongoing. Organizations like the National Institute of Standards and Technology (NIST) are actively involved in evaluating and selecting post-quantum cryptography (PQC) candidates. The transition to quantum-protected cryptography is a significant undertaking, requiring updates to software, hardware, and protocols across various industries. This transition is crucial to ensure the long-term security of sensitive data and communications in the emerging quantum era. The goal is to achieve "quantum readiness" before large-scale quantum computers become a reality.
