How is math used in cryptography?

Math is fundamental in cryptography, providing the algorithms and protocols that secure data. For example, prime numbers are used in RSA encryption.

Can you explain RSA encryption?

Sure! RSA encryption uses two keys: a public key for encryption and a private key for decryption. It relies on the difficulty of factoring large prime numbers.

What are some other mathematical concepts used in cryptography?

Other concepts include modular arithmetic, elliptic curves, and hash functions, all of which enhance security and efficiency.

How does modular arithmetic work in this context?

Modular arithmetic involves calculations where numbers wrap around after reaching a certain value, which is crucial for creating secure keys.

Are there any real-world applications of these concepts?

Yes, these mathematical principles are used in securing online transactions, messaging apps, and even blockchain technology.
