How many keys are used with asymmetric or public key cryptography?
Two
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. What must the receiver use to access the hashing value to verify the integrity of the transmission?
Sender’s public key
Which of the follow are characteristics of ECC? (Select two.)
Uses a finite set of values within an algebraic field
Asymmetric encryption
Which of the following algorithms are used in asymmetric encryption? (Select two.)
RSA
Diffie-Hellman
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 generates the key pair used in asymmetric cryptography?
CSP
Mary wants to send a message to Sam so that only Sam can read it. Which key would be used to encrypt the message?
Sam’s public key
Mary wants to send a message to Sam. She wants to digitally sign the message to prove that she sent it. Which key would Mary use to create the digital signature?
Mary’s private key
The strength of a cryptosystem is dependent upon which of the following?
Secrecy of the key
Which form of asymmetric cryptography is based upon Diffie-Hellman?
El Gamal
Which cryptography system generates encryption keys that could be used with DES, AES, IDEA, RC5 or any other symmetric cryptography solution?
Diffie-Hellman
Match each public-key cryptography key management mechanism on the left with the corresponding description on the right. Each mechanism may be used once, more than once, or not at all.
Implements the Diffie-Hellman key exchange protocol using elliptic curve cryptography
ECDH
Match each public-key cryptography key management mechanism on the left with the corresponding description on the right. Each mechanism may be used once, more than once, or not at all.
Exist only for the lifetime of a specific communication session
Ephemeral keys
Match each public-key cryptography key management mechanism on the left with the corresponding description on the right. Each mechanism may be used once, more than once, or not at all.
Uses no deterministic algorithm when generating public keys
Perfect forward secrecy
Match each public-key cryptography key management mechanism on the left with the corresponding description on the right. Each mechanism may be used once, more than once, or not at all.
Can be reused by multiple communication sessions
