How does randomness impact security in cryptography?

Randomness is crucial in cryptography as it ensures that keys and other cryptographic elements are unpredictable.

Can you explain why predictable keys are a security risk?

Predictable keys can be easily guessed or brute-forced by attackers, compromising the entire security system.

What methods are used to generate randomness in cryptographic systems?

Common methods include hardware random number generators, software algorithms, and environmental noise.

How do you ensure the randomness is truly random?

Testing methods like entropy estimation and randomness tests help verify the quality of generated random numbers.
