What is post-quantum cryptography?

What is post-quantum cryptography?

Post-quantum cryptography refers to cryptographic algorithms that are secure against the potential threats posed by quantum computers.

Why do we need post-quantum cryptography?

We need it to protect sensitive data from being decrypted by quantum computers, which could break traditional encryption methods.

How does it differ from classical cryptography?

It differs in that post-quantum cryptography is designed to be secure even when quantum algorithms, like Shor's algorithm, are applied.

What are some examples of post-quantum algorithms?

Examples include lattice-based cryptography, hash-based signatures, and multivariate polynomial cryptography.

When will post-quantum cryptography be widely adopted?

While some standards are being developed, widespread adoption may take several years as systems transition to new algorithms.
