Which of the following are potential attacks on cryptography? (Select 3)

A.
One-Time-Pad Attack

B.
Chosen-Ciphertext Attack

C.
Man-in-the-Middle Attack

D.
Known-Ciphertext Attack

E.
Replay Attack

Explanation:
A chosen-ciphertext attack (CCA) is an attack model for cryptanalysis in which the
cryptanalyst chooses a ciphertext and causes it to be decrypted with an unknown key. Specific
forms of this attack are sometimes termed “lunchtime” or “midnight” attacks,referring to a scenario
in which an attacker gains access to an unattended decryption machine. In cryptography,a man-inthe-middle attack (MITM) is an attack in which an attacker is able to read,insert and modify at
will,messages between two parties without either party knowing that the link between them has
been compromised. The attacker must be able to observe and intercept messages going between
the two victims. A replay attack is a form of network attack in which a valid data transmission is
maliciously or fraudulently repeated or delayed. This is carried out either by the originator or by an
adversary who intercepts the data and retransmits it,possibly as part of a masquerade attack by IP
packet substitution (such as stream cipher attack).
