94. Post-Quantum Cryptography

According to the essay, why are current cryptographic methods like RSA considered strong?
1. They are based on new mathematical approaches.
2. They would take normal computers thousands of years to break.
3. They are already resistant to quantum computer attacks.
4. They are being standardized by organizations like NIST.
The primary goal of post-quantum cryptography is to create methods that are
1. faster and more efficient than RSA and ECC.
2. safe for use against attacks from powerful quantum computers.
3. based on the same mathematics as current systems.
4. only for use by governments and banks.
How do the mathematical approaches of post-quantum cryptography differ from current systems?
1. They use the same mathematics but with longer codes.
2. They are based on entirely different approaches, such as lattice-based or code-based cryptography.
3. They are a simpler version of Elliptic Curve Cryptography.
4. They combine RSA and ECC into a single, stronger method.
The essay suggests we need to adopt post-quantum cryptography now, even though practical quantum computers don't exist yet, because
1. current computers are already breaking our codes.
2. data stolen today could be decrypted by quantum computers in the future.
3. the new algorithms are cheaper to implement.
4. it will make the internet faster.
What role does the National Institute of Standards and Technology (NIST) play, as described in the essay?
1. It is building the first practical quantum computer.
2. It is working to choose and standardize post-quantum algorithms for worldwide use.
3. It is responsible for breaking old cryptographic codes.
4. It develops the lattice-based and code-based mathematical theories.
