Multiple choice

In the field of computer security, what mathematical model is used to assess the security of cryptographic algorithms?

  1. Shannon's entropy

  2. Diffie-Hellman key exchange

  3. RSA encryption

  4. Elliptic curve cryptography
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Shannon's entropy is a mathematical model used to assess the security of cryptographic algorithms by measuring the uncertainty or randomness of a message. A higher entropy indicates a more secure algorithm, as it is more difficult for an attacker to predict the plaintext from the ciphertext.

Multiple choice
