Post-quantum cryptography (PQC)

What is Post-quantum cryptography (PQC)?

Post-quantum cryptography (PQC) refers to cryptographic algorithms designed to be secure against the potential threats posed by quantum computers. Unlike classical cryptographic methods, which could be easily broken by quantum algorithms like Shor's algorithm, PQC aims to develop new algorithms that can withstand quantum attacks. These algorithms are essential for ensuring the long-term security of data, as quantum computers become more advanced and capable of breaking traditional encryption methods. PQC focuses on creating robust encryption techniques that can protect sensitive information in a future where quantum computing is prevalent.
