Mary's private key

Above all else, what must be protected to maintain the security and benefit of an asymmetric cryptographic solution, especially if it is widely used for digital certificates?

Private keys

Which of the following is used in conjunction with a local security authority to generate the private and public key pair used in asymmetric cryptography?

CSP

Implements the Diffie-Hellman key exchange protocol using elliptic curve cryptography

ECDH

Diffie-Hellman

Which of the following algorithms are used in asymmetric encryption? (2)

Diffie-Hellman/ RSA

Which form of asymmetric cryptography is based up Diffie-Hellman?

El Gamal

Exist only for the lifetime of a specific communication session

Ephemeral keys

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. Which of the following must the receiver use to access the hashing value and verify the integrity of the transmission

Sender's public key

Digital signatures are created using

the sender's private key.

Uses no deterministic algorithm when generating public keys
