Which Of The Following Algorithms Are Used In Asymmetric Encryption

Question: Asymmetric encryption

Answer: An encryption method that uses two mathematically related keys called a key pair.

Question: Diffie-Hellman key exchange

Answer: The first asymmetric algorithm developed by Whitfield Diffie and Martin Hellman in 1976 that generates symmetric keys simultaneously at sender and recipient sites over non-secure channels.

Question: ElGamel

Answer: An asymmetric encryption system based on a discrete logarithm problem.

Question: Elliptic Curve Cryptography (ECC)

Answer: An asymmetric encryption system based on groups of numbers in an elliptical curve.

Question: Merkle-Hellman Knapsack

Answer: An asymmetric encryption system based on the subset sum problem (given a list of numbers and a sum, determine the subset used to create the sum).

Question: Rivest Shamir Adleman (RSA)

Answer: An asymmetric encryption system based on factoring large numbers into their prime values.

Question: How many keys are used with asymmetric (public key) cryptography?

Answer: Two

Question: A receiver wants to verify the integrity of a message received from a sender. A hashing value is contained within the digital signature of the sender.
