Question

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

(a) Symmetric cryptography

(b) Asymmetric cryptography

(c) Diffie-Hellman key exchange

(d) Secret key cryptography

I had been asked this question by my college director while I was bunking the class.

The query is from Discrete Probability in division Discrete Probability of Discrete Mathematics

Answer 1

The correct option is (c) Diffie-Hellman key exchange

Explanation: A discrete logarithm modulo of an integer to the base is an integer such that a^x ≡ b (mod g). The problem of computing the discrete logarithm is a well-known challenge in the field of cryptography and is the basis of the cryptographic system i.e., the Diffie-Hellman key exchange.
