Post-quantum cryptography refers to cryptographic algorithms designed to be secure against attacks by future quantum computers. As quantum computers advance, they pose a threat to current widely used cryptographic methods, such as RSA and ECC. Developing and deploying these new algorithms is crucial for safeguarding sensitive data in the long term.
