Question

Computation of the discrete logarithm is the basis of the cryptographic system:

• A. Symmetric key cryptography
• B. Asymmetric cryptography
• C. Diffie-Hellman key exchange
• D. Secret key cryptography

Hint:

Discrete logarithms are central to Diffie-Hellman and ElGamal cryptographic systems.

Answer 1

The Correct Option is C

Diffie-Hellman key exchange utilizes the computational difficulty of discrete logarithms in a finite field. This mathematical foundation enables the secure generation of a shared secret over an insecure channel.
