Kerberos depends upon what encryption method?
A.
Public Key cryptography.
B.
Secret Key cryptography.
C.
El Gamal cryptography.
D.
Blowfish cryptography.
Explanation:
During the Kerberos Authentication Process, the user and the KDC share a secret key, while the service and
the KDC share a different secret key. Kerberos is, therefore, dependent on Secret Key cryptography.
Incorrect Answers:
A: Kerberos is dependent on Secret Key cryptography, not Public Key cryptography.
C: El Gamal is a public key algorithm that can be used for digital signatures, encryption, and key exchange.
Kerberos is not, however, dependent on it.
D: Blowfish is a block cipher that works on 64-bit blocks of data. Kerberos is not, however, dependent on it.Harris, Shon, All In One CISSP Exam Guide, 6th Edition, McGraw-Hill, 2013, pp. 209-213, 810, 818
