Cryptography

Which of the following asymmetric encryption algorithms is founded on the difficulty of factoring large numbers?

  • A El Gamal
  • B Elliptic Curve Cryptosystems (ECCs)
  • C RSA
  • D International Data Encryption Algorithm (IDEA)
Explanation

RSA uses a public modulus that is the product of large prime numbers; deriving the private key from that modulus is tied to the difficulty of factoring the large composite number.
