Which
of the following is the process of finding weaknesses in cryptographic algorithms and obtaining the
plaintext or key from the ciphertext?

A.
Kerberos

B.
Cryptography

C.
Cryptographer

D.
Cryptanalysis

Explanation:
Cryptanalysis is the process of analyzing cipher text and finding weaknesses in
cryptographic algorithms. These weaknesses can be used to
decipher the cipher text without knowing the secret key.
Answer option A is incorrect. Kerberos is an industry standard authentication protocol used to verify
user or host identity. Kerberos v5
authentication protocol is the default authentication service for Windows 2000. It is integrated into
the administrative and security model, and
provides secure communication between Windows 2000 Server domains and clients.
Answer option C is incorrect. A cryptographer is a person who is involved in cryptography.
Answer option B is incorrect. Cryptography is a branch of computer science and mathematics. It is
used for protecting information by encoding
it into an unreadable format known as cipher text.
