Kerberos is an authentication scheme that can be used to implement:
A.
Hash functions.
B.
Single Sign-On (SSO).
C.
Public key cryptography.
D.
Digital signatures.
Explanation:
The correct answer is “Single Sign-On (SSO).”. Kerberos is a third-party authentication protocol that
can be used to implement SSO. Answer “Public key cryptography” is incorrect because public key
cryptography is not used in the basic Kerberos protocol. Answer “Digital signatures” is a public keybased capability, and answer “Hash functions” is a one-way transformation used to disguise
passwords or to implement digital signatures.
